Overview
1-
Active Upgrade™ technology allows you to upgrade system and application software
on an Express5800/320Fc system with minimal downtime.
Instead of taking your system offline to run upgrade procedures, you can use Active
Upgrade technology to split the system into two independently running systems, one
side of which you upgrade while the other side continues to run your applications
without interruption.
To learn more about Active Upgrade technology, see the following topics:
• “Features”
• “Overview of the Active Upgrade Process” on page 1-2
• “Active Upgrade State Model” on page 1-9

Features
Active Upgrade technology allows you to do the following:
• Install software updates with minimal disruption to your critical applications.
Your business-critical applications continue to run on one side of the system while
you install software on, and even restart, the other side. There is only a brief
disruption when you are finished installing updates, as your critical applications are
restarted on the upgraded software.
Overview 1-1

Overview of the Active Upgrade Process
• Test the latest software updates in your environment before making the updates
permanent.
After your critical applications are restarted on the upgraded software, you can
verify the success of your software updates in a production environment, with real
users and system load. If you want to keep the changes, there is no additional
downtime. Otherwise, as quickly as your system can restart, you can abort the
upgrade to go back to the original version of your software.
• Abort the upgrade process at any point, until you commit the changes.
If, for any reason, you are not satisfied with an upgrade, you can abort the upgrade
session to return the system to its original state. Nothing is permanent until you
choose to commit the changes. (Also, if you abort the upgrade early enough in the
process, before testing the software in your production environment, your critical
applications are not disrupted.)

Overview of the Active Upgrade Process
The Active Upgrade process involves the following basic steps:
1. You prepare your system to ensure it meets the prerequisites of the upgrade
process.
2. You use the Active Upgrade console to select the disks that are affected by the
software upgrade and to provide information about any applications or services
that require special handling during the upgrade process.
3. You run a readiness check in the Active Upgrade console to confirm that your
system meets the prerequisites for the upgrade process.
4. You start the upgrade process by initiating split mode, which divides the
fault-tolerant, duplexed system (Figure 1-1) into two independent, simplexed
systems (Figure 1-2) — a Production Side, which continues to run your
applications, and an Upgrade Side, on which you can run software installation
packages.

Overview of the Active Upgrade Process
As shown in Figure 1-2, when you split the system, the Active Upgrade console
disables any Rapid Disk Resync (RDR) mirroring between the internal disks in
each CPU-I⁄ O enclosure and isolates the Upgrade Side from system resources
such as the network, any user-specified application data disks, and any external
PCI resources. It also disables user-specified applications and services on the
Upgrade Side so they cannot restart if you restart the Upgrade Side.
Meanwhile, the Production Side retains access to system resources and continues
to run your applications uninterrupted.
5. After the system successfully enters split mode, you establish a remote connection
to the Upgrade Side of the system through the private network that exists between
the VTM adapters in each CPU-I⁄ O enclosure. Using this remote connection, you
can perform any of the following upgrade tasks on the Upgrade Side:
• Run software installation programs (see “Software Upgrade Support” on
page 2-1 for restrictions).
• Restart the operating system, if necessary.
• Perform limited testing of the installed updates. (The Upgrade Side has no
access to the network or application data disks during this stage.)
You can also completely abort the upgrade from the Active Upgrade console, if
necessary.
6. When you are finished installing software on the Upgrade Side, you disconnect the
remote connection to the Upgrade Side and initiate the merge process.
When you merge the system, the Active Upgrade console stops your applications
on the Production Side and unmounts any application data disks to ensure that
pending disk updates are flushed to disk. It then merges system resources so that
the network and application data disks become available to the whole system
again. With the exception of the internal disks, all critical system resources return
to duplex mode (Figure 1-3).

duet003
Finally, the system restarts your applications, including the Active Upgrade
console, from the Upgrade Side system disk. Depending on the complexity of your
applications and the upgrade you performed, your applications may be back up and
running in under a minute.
7. After the system is successfully merged, you can test your applications and verify
the success of your upgrades with full access to the system’s resources. If you
discover a problem, you can still abort the upgrade process and restore the system
to its previous state, because the original copy of your system disk (on the
Production Side) has not been overwritten yet.
8. When you are certain that the upgrades were successful, you can commit the
changes to make them permanent.
When you commit the changes, the Active Upgrade console resynchronizes the
RDR disks in your system by overwriting the original Production Side system disk
and stale Upgrade Side data disks with their partner disks, which are up-to-date
(Figure 1-4).
N O T E
Because the original version of your system disk is erased
during the commit process, you cannot abort an upgrade
session after initiating the commit process.

When the RDR disk resychronization is finished, all critical system resources are
running in duplex mode, and the Active Upgrade process is complete. You do not
need to restart the system, and, because your application is already running on the
upgraded software, there is no additional downtime.

Aborting the Active Upgrade Process
Aborting the Active Upgrade process stops the current upgrade session and returns
your system to its original state. If necessary, you can abort an upgrade session at any
point up until you commit the upgrade.
If you abort the upgrade session while the system is in split mode, no downtime is
incurred. Your applications continue to run on the Production Side while the Active
Upgrade console restores the system to duplex mode.

Download from Www.Somanuals.com. All Manuals Search And Download.
Overview of the Active Upgrade Process
If you abort the upgrade session while the system is in merge mode, a short period of
downtime is incurred while the Active Upgrade console initiates a system restart. The
Active Upgrade console shuts down the Upgrade Side and restarts the system from the
Production Side, which automatically restarts your applications from the Production
Side. The period of downtime is only as long as it takes your system and applications
to restart.
In either case, the abort process uses RDR resynchronization to restore the internal
disks to their original state by overwriting the unwanted Upgrade Side system disk and
stale Upgrade Side data disks with their original partner disks (Figure 1-4).

The state model helps to demonstrate the sequence of events in the Active Upgrade
process, as follows:
1. All upgrade sessions start in the Idle state, where you can run the readiness check
as many times as necessary to verify that your system meets the prerequisites of
the upgrade process. The system continues to run normally, and both sides of the
system continue to be synchronized.
2. When you start an upgrade session, the Active Upgrade console switches to the
PrepareSplit state, during which it runs a final readiness check and additional
background tasks. If the system is ready, the console immediately switches to the
Split state and proceeds to divide the system into two independently running
systems.

Overview of the Active Upgrade Process
N O T E
After the upgrade session leaves the Idle state, you must
complete the full upgrade process in sequence or abort
the process altogether. You cannot go back to a previous
state or skip states, and you cannot proceed to the next
state if the upgrade is in a Broken or Busy operational
state.
3. When you are done installing software on the Upgrade Side and you start the
merge process, the Active Upgrade console switches to the PrepareMerge state,
during which it runs additional readiness tests and background tasks. If the system
is ready, the console immediately switches to the Merge state and restarts your
applications on the Upgrade Side.
4. When you are satisfied that everything is working correctly and you start the
commit process, the Active Upgrade console switches to the Commit state, during
which it starts the resynchronization of your RDR disks. You can subsequently start
the finish process, during which the Active Upgrade console switches to the Finish
state, cleans up system resources, and then returns the system to the Idle state.
The upgrade session is complete.
If necessary, you can abort the upgrade process from the PrepareSplit, Split,
PrepareMerge, and Merge states. When you abort an upgrade session, the Active
Upgrade console switches to the Abort state, during which it restores your system to
its original configuration and starts the resynchronization of your RDR disks. You can
subsequently initiate the finish process, as you would after committing an upgrade.
Alternatively, you can retry any of the Active Upgrade states to recover the system from
a transient failure and move on to the next states without aborting the entire upgrade
session.
All of these Active Upgrade states are reported in the activity log and status bar of the
Active Upgrade console during the upgrade process. See “Understanding the Active
Upgrade Console Interface” on page 2-20 for more information.

Preparing for the Active Upgrade
Process
2-
Preparing for the Active Upgrade process involves the following tasks:
• Learning about the types of upgrades that the Active Upgrade process supports.
• Learning about the prerequisites and recommendations for your
Express5800/320Fc system.
• Learning how the Active Upgrade console can control your critical applications.
• Performing pre-upgrade tasks on your system, such as:
• Installing the Active Upgrade console.
• Configuring Windows Firewall for the Active Upgrade process.
• Configuring a UPS-protected system for the Active Upgrade process.
• Gathering information about your system.
• Copying any software installation packages to the system before the upgrade
starts.
• Configuring Microsoft Windows Automatic Updates.
• Starting the Active Upgrade console.
• Understanding the Active Upgrade console.
Software Upgrade Support
Active Upgrade technology currently supports the installation of high-priority updates
(also known as hotfixes) for the Microsoft Windows Server 2003 operating system. It
also supports the installation or upgrade of application software that meets the
following criteria:
• The application’s executable files, configuration files, and temporary files (for
example, cache files) reside on internal system disks that are mirrored with RDR.
• The application’s persistent data files reside on separate data disks, either internal
or external. (Data volumes that reside on the same physical disk as a system
volume are not supported.)
Preparing for the Active Upgrade Process 2-1
Download from Www.Somanuals.com. All Manuals Search And Download.
System Prerequisites
• The application’s installation or upgrade utility does not involve changes to files or
databases on the data disks while the system is in split mode. (For example, the
utility cannot create new databases or convert existing data records to be
compatible with the new version of the application). The Upgrade Side has no
access to the data disks while the system is split.
Active Upgrade technology does not support the following types of upgrades:
• Any upgrade that requires network connectivity during the upgrade process.
For example, you cannot use an installation program that downloads its installation
files from the Internet as the upgrade progresses. If possible, you must download
the complete installation package to the system prior to initiating split mode.
• BIOS, BMC, or VTM firmware updates, which you can already perform while the
system is duplexed and online. See the Express5800/320Fc: User Guide
for more information.

System Prerequisites
Active Upgrade technology is supported only on Express5800/320Fc
systems that:
• Are running in duplex mode prior to starting the upgrade process.
The CPU-I⁄ O enclosures must be duplexed, and all critical resources in the
enclosures must be duplexed.
A critical resource is a device (such as a CPU, hard disk, or host bus adapter) that
is necessary to maintain fault tolerance. Non-fault-tolerant resources (such as tape
drives) connected to the system do not affect the Active Upgrade process.
• Contain teamed embedded Ethernet PCI adapters.
All embedded Ethernet PCI adapters must be teamed with the Intel PROSet utility,
and each Ethernet team must contain at least one Ethernet PCI adapter from each
CPU-I⁄ O enclosure. Furthermore, at least one team of embedded Ethernet PCI
adapters must have an active network link in each CPU-I⁄ O enclosure.
2-2 Express5800/320Fc: Active Upgrade™ User’s Guide
Download from Www.Somanuals.com. All Manuals Search And Download.
System Prerequisites
All ports on any dual-port adapter must be either teamed or not teamed. You cannot
have only one port on an adapter teamed.
You do not need to team non-embedded Ethernet PCI adapters for the Active
Upgrade process, but it is best to do so to ensure that the network connectivity
provided by these adapters continues to be available throughout the upgrade
process. The readiness check in Active Upgrade console displays a warning for
each unteamed Ethernet PCI adapter, but the warnings do not prevent you from
proceeding with the upgrade process.
N O T E
If you modify the configuration of your Ethernet PCI
adapters and Ethernet teams to meet these prerequisites,
it could impact network connectivity for the system. You
should schedule this work to minimize impact to your
critical applications.
See the Express5800/320Fc: User Guide for more information about
configuring Ethernet PCI adapters and Ethernet teams.
• Contain Virtual Technician Modules (VTMs).
The VTMs provide the connection between the Production Side and Upgrade Side
during the Active Upgrade process. Both VTMs must be configured properly and
connected to the same subnetwork, preferably on a dedicated maintenance
network.
• Can tolerate running in simplex mode for a brief period during the upgrade.
Because each side of the system runs in simplex mode during the upgrade, an
interruption on the side that is actively running your critical applications can result
in downtime.
C A U T I O N
!
You cannot restart the operating system on the Production
Side during an upgrade (though you can restart the
Upgrade Side as many times as necessary.) Also, it is
unsafe to pull an enclosure from a split-mode, simplexed
system because doing so terminates all processes
running on that enclosure.
Preparing for the Active Upgrade Process 2-3
Download from Www.Somanuals.com. All Manuals Search And Download.
System Prerequisites
• Can tolerate a potential decrease in performance during the upgrade.
For example, if your system contains teamed network adapters that are configured
for load balancing or link aggregation, there might be a decrease in network
performance when the system is split because the network adapters on the
Upgrade Side lose access to the network.
• Are running Express5800/320Fc System Software Release 5.0 or higher.
• Have been updated with the latest firmware to support Active Upgrade technology,
including required BMC and VTM updates.
Furthermore, the Active Upgrade process has the following storage requirements:
• All internal hard disks must be configured with RDR and must be duplexed
(synchronized) before the upgrade process starts.
• The operating system boot volume and all active Windows operating system
components must be located on internal RDR disks. This includes any volumes
that contain paging (virtual memory) files for the operating system.
• Any disk that contains software you want to upgrade cannot contain persistent
data files for your business-critical applications (those applications that continue to
run during the upgrade process). You must store your data files on separate data
disks, either internal or external. (Data volumes that reside on the same physical
disk as a system or paging volume are also not supported.)
• External storage devices are always considered data disks. You cannot upgrade
software on external storage devices, as these devices not available to the
Upgrade Side of the system while the system is in split mode.

Recommendations
Recommendations
When preparing your system for the Active Upgrade process, also consider the
following recommendations:
• If possible, assign static IP addresses for embedded Ethernet teams and VTM
adapters.
• If your system is protected by Windows Firewall, enable the exceptions for Active
Upgrade console and Remote Desktop as shown in “Configuring Windows Firewall
for the Active Upgrade Process” on page 2-10.
If Windows Firewall is running, and these exceptions are not enabled,
communication between the Production Side and Upgrade Side might fail during
the upgrade process.
• If your system is protected by an uninterruptible power supply (UPS), ensure that
the CPU-I⁄ O enclosure with A-side power (CPU enclosure 0, I/O enclosure 10) is
marked as the Primary enclosure in ESMPro before starting the upgrade process.
This configuration provides better protection for your system should power fail
during an upgrade. See “Configuring a UPS-Protected System for the Active
Upgrade Process” on page 2-11 for more information.
• Use caution when applying hotfixes from any source. Applying updates
indiscriminately may introduce serious problems to your system.
• You should install all Microsoft Security hotfixes (identified by the prefix MS).
• Do not install other types of hotfixes, such as Microsoft patches that fix a
particular problem, before obtaining validation from NEC Corporation of
America.
Please refer to NEC Corporation of America's support website for infromation
pertaining to the application of Microsoft Windows patches, hotfixes, and
service packs. http://support.necam.com/servers/ft

Managing Critical Applications During the Upgrade Process
The Active Upgrade console allows you to specify how business-critical applications
are started and stopped during the Active Upgrade process.
If your system runs business-critical applications, such as Microsoft Exchange Server
or SQL Server, these applications can run on only one side of the system—the
Production Side—when you split the system. They must be stopped on the other side—
the Upgrade Side—to prevent resource conflicts and to allow you to proceed with
upgrade tasks. Furthermore, when you merge the system, the same applications must
be stopped on the Production Side and restarted on the Upgrade Side, so you can test
the applications with the newly-upgraded system disk, and possibly commit the
upgrade.
Typically, critical applications are started and stopped automatically by the operating
system. For example, your application might be configured to start as a service in the
Services Control Manager, or as a startup item in the system registry. But these
resources control your applications only when the operating system itself is started or
stopped. In most cases, to minimize downtime, the Active Upgrade console executes
upgrade operations, like split and merge, without restarting the operating system.
Therefore, if you want your applications to start and stop at the appropriate times during
the upgrade process, you must configure the Active Upgrade console itself to control
the applications
Active Upgrade console provides two methods for controlling your critical applications
during the upgrade process. The method you use for each application depends on the
type of application you want to control:
• Application services
2-6 Express5800/320Fc: Active Upgrade™ User’s Guide
Download from Www.Somanuals.com. All Manuals Search And Download.
Pre-Upgrade Tasks
If your application runs as a standard service that already accounts for
interdependencies (with other services) and requires no special handling, you can
specify it on the Application Services page of the Active Upgrade console during
the configuration process. On the Application Services page, you can select each
service you want to manage from the list of services on your system, and, when
you start the upgrade process, the Active Upgrade console automatically starts and
stops these services at the appropriate times. See “Selecting Application Services
to Control” on page 3-9 for more information.
• Custom actions
If you have a custom application or integrated applications from several different
software vendors, and you have special executable files that start and stop these
applications, you can specify the executable files on the Custom Actions page of
the Active Upgrade console during the configuration process. Using the controls on
the Custom Actions page, you can specify when your executable files will run
during the upgrade process, and, if you have several files, you can specify the order
in which they will run. See “Configuring Custom Actions” on page 3-12 for more
information.

the system.
To install and run the Active Upgrade console, your user account must be in the
Administrators group. Furthermore, because the Upgrade Side of the system has
no access to the network while the system is in split mode, your administrator
account must be a local system account, not a domain account.
7. Install Java Runtime Environment as described in “Installing Java Runtime
Environment” on page 2. -13
8. Install the Active Upgrade console as described in “Installing the Active Upgrade
Software” on page 2-9.
9. If necessary, enable access for Remote Desktop connections from the Production
Side to the Upgrade Side of the system while the system is in split mode, as follows:
a. Open the System control panel.
b. Click the Remote tab to display remote settings.
c. Under Remote Desktop, click the check box next to Allow users to remotely
connect to this computer to activate it.
d. Click OK or Apply to save the setting.
(You need to use either Remote Desktop or Remote KVM to connect to the
Upgrade Side to perform upgrade tasks. For more information, see “Connecting to
the Desktop on the Upgrade Side” on page 4-6.)
10. If applicable, enable the exceptions for Active Upgrade console and Remote
Desktop in Windows Firewall properties, as shown in “Configuring Windows
Firewall for the Active Upgrade Process” on page 2-10.
11. If applicable, ensure that the CPU-I⁄ O enclosure with A-side, UPS-protected
power (CPU enclosure 0, I/O enclosure 10) is the primary, active enclosure, as
shown in “Configuring a UPS-Protected System for the Active Upgrade Process”
on page 2-11.
12. Gather information about your system using the worksheet in “Gathering
Information” on page 2-15.
13. If necessary, copy any required software installation packages to the system, as
described in “Copying Software Installation Packages to the System” on page 2-18.

Configuring Windows Firewall for the Active Upgrade Process
The Active Upgrade console requires network access to:
• Communicate with system components and underlying services in the ftServer
System Software.
• Allow communication between the Production Side and the Upgrade Side while the
system is split, so you can perform upgrade tasks.
If you have enabled Windows Firewall to protect your system, it might prevent you from
using some of the features of Active Upgrade console; therefore, you should enable the
exception for the Active Upgrade console in your Windows Firewall settings.
N O T E S
1. Install the Active Upgrade software before modifying
your Windows Firewall settings. If Windows Firewall is
enabled on your system, the installation process adds
an entry for the Active Upgrade console to the list of
Windows Firewall exceptions. This entry is disabled
by default.
2. If you enable Windows Firewall after installing the
Active Upgrade software, you can reinstall the Active
Upgrade software to add the exception to Windows
Firewall.
To configure Windows Firewall
1. Open the Windows Firewall control panel.
2. Click the Exceptions tab to display the list of exceptions (Figure 2-1).
3. Click the check box next to Active Upgrade Software to activate it.
4. Click the check box next to Remote Desktop to activate it. (This allows you to
connect to the Upgrade Side with Remote Desktop while the system is in split

Configuring a UPS-Protected System for the Active Upgrade Process
If your system is protected by a UPS, and you have configured the UPS power
connections as specified in the Express5800/320Fc: Site Planning Guide, it is best to
ensure that the CPU-I⁄ O enclosure with A-side, UPS-protected power (CPU
enclosure 0, I/O enclosure 10) are Primary before starting the Active Upgrade
process.
When you initiate the upgrade process and split the system, the primary (active)
CPU-I⁄ O enclosure becomes the Production Side of the system. Because the
Production Side controls the upgrade session for most of the Active Upgrade process,
and also contains the most current version of your data disks during the upgrade
process, allowing the Production Side to run on UPS power provides better protection
for your system should power fail during an upgrade.

Pre-Upgrade Tasks
Gathering Information
Before you start configuring the Active Upgrade process on your system, considering
the following questions:
❏ After you complete this upgrade, will you ever want to run the same type of upgrade
again? If so, plan to create a configuration file with the details of your upgrade, so
you can use it again at a later date.
❏ Did your support provider give you a configuration file that you could use as a
template for your specific system and the type of upgrade you are performing? Or,
do you have settings from other existing configuration files that you want to
incorporate into your current configuration? (If applicable, you might be able to use
more than one configuration file at a time by nesting them).
❏ Which disks in your system contain the software you want to upgrade? Which disks
cannot or should not be upgraded given the prerequisites of the Active Upgrade
process? You need to select these disks before splitting the system.
❏ Which software installation utilities are you going to run during the Active Upgrade
process? (If you are copying these to the system from a network resource, you
need to do so before initiating split mode.) Do any of these installation programs
require access to the network or data disks during the upgrade? (If so, you cannot
use them with Active Upgrade technology.)
❏ How do you start and stop critical applications on the system you want to upgrade?
Are the applications configured as services in the Services snap-in to Microsoft
Management Console? Or do you need to run custom actions (executable files
such as .bat, .vbs, .exe) to start your applications, possibly in a particular order?
You need to identify these services and custom actions during configuration to
allow the Active Upgrade console to start and stop your applications at the
appropriate times during the upgrade process. See “Managing Critical Applications
During the Upgrade Process” on page 2-6 for more information.
❏ Do you want to preserve Event Viewer log entries that are generated on the
Production Side while the system is running in split mode? These log entries are
typically lost during the commit process, when the system resynchronizes your
RDR disks. If you want to save the files, you can configure the Active Upgrade
console to copy them to a backup directory before it commits the upgrade. You can
save the standard log files as well as any custom log files you have opened in the
Event Viewer.
When you finish answering these questions, you can use the worksheet in Table 2-1 to
record your configuration information.

Copying Software Installation Packages to the System
When the system runs in split mode, the Upgrade Side has no access to the network,
or internal data disks; therefore, if you need to download or copy any High Priority
updates (hotfixes), installation packages, or disk images (for example, .msi files) to the
system, put them on one of the disks you want to upgrade before you split the system.
You might want to do so even before you run the Active Upgrade console.
Make note of the location of the installation packages so you can find them later.
N O T E
If your installation packages are on CD-ROM, no action is
necessary. You can access the CD/DVD drive on the
Upgrade Side while the system is in split mode.
For more information about downloading updates with the Microsoft Windows
Automatic Updates utility, see “Configuring Windows Automatic Updates”.

Configuring Windows Automatic Updates
When the system runs in split mode, the Upgrade Side has no access to the network.
Windows Automatic Updates requires network access to download software updates;
therefore, if you manage High-Priority updates (hotfixes) with Automatic Updates, you
must use it to download all of the updates you need to the system before you split the
system.
You can optionally configure Automatic Updates to automatically download the
software updates for you; however, you must be able to install the updates on your own
schedule, while the system is split.
To configure Automatic Updates
1. Open the Automatic Updates control panel (Figure 2-2).
2. Select Download updates for me, but let me choose when to install them.
3. Click OK to save the configuration.

If your company pushes software updates from an enterprise-wide service, like
Windows Server Update Services (WSUS), you might need to override the default
Automatic Update policies for your system.
Typically, WSUS clients are set to install all critical updates at a time specified by the
WSUS administrator. The Automatic Update control panel on the client system can be
locked to enforce this policy. If the control panel on your system is locked, you must
ask the WSUS administrator for permission to modify your update policies.
After you configure Automatic Updates, the utility starts downloading updates in the

Understanding the Active Upgrade Console Interface
You can click Active Upgrade to perform a readiness check, and, if you are still
modifying a configuration file, you can click any page in the Configuration section to
go back and make additional changes.
After you initiate an upgrade session (by clicking Split on the Active Upgrade page),
the navigation bar reverts to a static mode, in which it only indicates where you are in
the upgrade process and does not allow you to skip between pages. At that point, you
use the controls in the main window to complete the upgrade process.
The pages in the Active Upgrade section of the navigation bar have the following
purposes:
Active Upgrade — Allows you to perform a readiness test, and if applicable, to
split the system for an upgrade.
• Split System — Indicates that the system is entering split mode, and allows
you to merge system resources (or abort the upgrade) after you finish running
installation packages.
• Merge System — Indicates that the system is entering merge mode, and
allows you to commit (or abort) the upgrade after you have tested your
changes.
• Commit Upgrade — Indicates that the system is committing the upgrade, and
allows you to finish the process by cleaning up system resources.
• Abort Upgrade — Indicates that the upgrade process has been aborted, and
allows you to finish the process by cleaning up system resources. (You can
abort the upgrade process at any point prior to committing the upgrade.)
• Finish — Indicates that the upgrade process is complete and allows you to
save a copy of the activity log to a file, start another upgrade, or exit the Active
Upgrade console.
The navigation bar also contains the Links shown in Figure 2-7, which are active only
while the system is running in split mode.

Configuring the Active Upgrade
Process
3-
Configuring the Active Upgrade process involves the following tasks:
• Creating and managing configuration files
• Selecting disks to upgrade
• Selecting other configuration files to include
• Selecting application services to control
• Selecting event log files to back up
• Configuring custom actions
• Providing a description for a configuration file
• Displaying the upgrade summary
Creating and Managing Configuration Files
Configuration files allow you to save upgrade configurations that you can use
immediately or in the future.
If you frequently perform upgrades to your system, you can create a configuration file
to preserve your settings so you can perform similar upgrades as often as necessary.
If applicable, you can create multiple configuration files, each with different system
settings, to prepare the system for a particular type of system or application software
upgrade.
In addition, you can call one or more existing configuration files from the configuration
file you are currently editing, so that the settings from the called files will also apply to
the file you are editing. This is called nesting.
The default location for Active Upgrade configuration files is
\Program Files\ftsys\ActiveUpgrade\User Configurations, but you can save a
configuration file in any directory. If you specify a different directory when saving or
opening files, the Active Upgrade console uses the same user-specified directory (on
a per-user basis) the next time you open the file browser.

Creating and Managing Configuration Files
N O T E
You can save a configuration file to any disk — system or
data, internal or external. The Active Upgrade console
automatically copies configuration files to a staging area
before beginning the upgrade to ensure that they are
available throughout the upgrade process.

Creating a Configuration File
Creating a configuration file allows you to generate a configuration file that you can
save and use immediately or at a later time.
To create a configuration file
1. On the Configuration page, click Create Configuration File.
2. In the Create Configuration File dialog box, specify a file name for the new file.
(When you save the file, a .Config extension is automatically appended to the file
name.)
3. Next to Save in, select the directory in which to save the configuration file.
You can specify any directory on the system. The default location is
\Program Files\ftsys\ActiveUpgrade\User Configurations; however, if you
choose a new configuration directory, the Active Upgrade console uses the new
directory the next time you create or open a file.
4. Click Save to start editing the configuration.
After you create a configuration file, the configuration process opens on the Disk
Selection page.

Performing an Upgrade with No Configuration File
If the upgrade you want to perform does not require any special settings, you can
proceed without a configuration file.
For example, if you have only one system disk, and you just want to split the system
briefly to test how a hotfix would affect the operating system without committing the
changes, you might not need a configuration file.
To proceed without a configuration file, click No Configuration File on the
Configuration page. The Active Upgrade console immediately displays the Active
Upgrade page and runs a readiness check. If your system meets the prerequisites for
the Active Upgrade process, you can split the system at this time.

Selecting Disks to Upgrade
Use the Disk Selection page to select the disks that contain the software you want to
upgrade with the Active Upgrade process. By marking these disks in your upgrade
configuration, you ensure that they will be available to the Upgrade Side of the system
when the system is in split mode.
When you open the Disk Selection page, the Active Upgrade console scans for and
displays the disks in your system. Only internal disks mirrored with RDR are
displayed, because these are the only disks that can be configured.
Configuring the Active Upgrade Process 3-5
Download from Www.Somanuals.com. All Manuals Search And Download.
Selecting Disks to Upgrade
You can mark each disk as a system disk or a data disk:
• System disk
A disk that contains the system or application software you want to upgrade. Only
disks marked as System are available to the Upgrade Side while the system is
split.
The Active Upgrade console automatically marks some disks as system disks.
These mandatory system disks contain either boot files or paging files (virtual
memory files) that are currently in use by the running operating system. (For more
details, see the mandatory system disk glossary entry.) You cannot change a
mandatory system disk to a data disk.
C A U T I O N
!
You cannot use a system disk for storing persistent data
(for example, database files) related to your critical
applications. Any new data written to the original system
disk by the Production Side while the system is in split
mode is overwritten when you commit the upgrade. (See
the Overview for information about the steps of the Active
Upgrade process.)
• Data disk
A disk that contains persistent data for your critical applications. Any disk marked
as Data is available only to the Production Side while the system is split. You
cannot upgrade software on a data disk.
(See the prerequisites for the Active Upgrade process for additional restrictions.)
Volumes on the Disk Selection page are color-coded as described in Table 3-1.

Selecting Other Configurations to Include
For more information about any volume, move your cursor over the volume to display
ToolTip help.
To select system and data disks
• For any disk you want to mark as a system disk, click System. (This automatically
marks any volume that the disk contains as a System volume.)
• For any disk you want to mark as a data disk, click Data.
N O T E
Volumes can span multiple physical disks, and physical
disks can contain multiple volumes. If a volume spans two
or more disks, and you mark one of the disks that contains
that volume as a system disk, any disk that contains a part
of that volume automatically becomes a system disk.
When you are finished selecting disks, you can click Next to proceed with the next
configuration step.

• “System Prerequisites” on page 2-2
• “Displaying the Upgrade Summary” on page 3-19
Selecting Other Configurations to Include
Use the Other Configurations page to optionally call one or more existing
configuration files into the configuration file you are currently editing, so that the
settings from the called files will also apply to the file you are editing. This is known as
nesting files, or creating nested files.
The configuration files that you call into the current configuration file are child
configurations, and the file from which you call the child configurations is the parent
configuration.
Configuring the Active Upgrade Process 3-7
Download from Www.Somanuals.com. All Manuals Search And Download.
Selecting Other Configurations to Include
Potential uses for nested files include:
• Your support provider creates a configuration file that you can call into an existing
configuration file for your system.
• You create separate configuration files, each for upgrading a different application,
which you can enable or disable at will in your parent configuration.
• You create a configuration file for an application that runs on several of your
systems and call that file into a parent configuration file that is specific to each
system.
The following restrictions apply to nested files:
• Child configuration files must be located in the same directory as the files in which
they are called. When you select configuration files in the Active Upgrade console,
only files in the present working directory are displayed.
• If you call a configuration file, and that file itself has one or more child configuration
files, those child configuration files also become part of your configuration.
• If a setting in a child configuration conflicts with a setting in the parent configuration,
the Active Upgrade console uses the setting in the parent configuration. Also, the
parent configuration always ignores disk selections from child configurations.
• If you call a configuration that you created on a different system, configuration
items (for example, application services and custom actions) must be present and
applicable on the current system, otherwise the parent configuration fails the
readiness check.
To call a child configuration file into the current file
1. On the Other Configurations page, select the check box next to the configuration
files you want to call into the current file.
2. In the file window, verify that you have selected the correct configuration files. Also,
if any of the files contain additional child configurations, ensure that you are
including only the configurations that apply to the current parent file.
3. When you are finished editing the current configuration, save the configuration file.
To remove a child configuration file from the current configuration, clear the check box
next to that configuration file. (If you need to remove a child configuration from another
configuration file, you must edit that configuration file separately.)
When you have finished specifying child configuration files, you can click Next to
proceed with the next configuration step.

Selecting Application Services to Control
Related Topics
• “Creating and Managing Configuration Files” on page 3-1
• “Saving a Configuration File” on page 3-5
• “Displaying the Upgrade Summary” on page 3-19
Selecting Application Services to Control
Use the Application Services page to select the critical application services you want
the Active Upgrade console to automatically stop and restart during the upgrade
process.
If you select a service on the Application Services page, the Active Upgrade console
controls the service as follows:
• When the system is split, the console saves the current Startup Type for the
service, changes the Startup Type to Disabled on the Upgrade Side, and then
stops the service on the Upgrade Side.
• When the system is merged, the console stops the service on the Production Side,
restores the previous Startup Type for the service on the Upgrade Side, and starts
the service on the Upgrade Side. This ensures continuous availability of the
service, allows for comprehensive testing on the Upgrade Side, and prevents any
conflicts associated with two instances of a service running at the same time.
• When an upgrade is aborted, if the system is in merge mode, the console shuts
down the Upgrade Side (which automatically stops the service) and restarts the
Production Side (which automatically starts the service based on its default
Startup Type). This returns the system to its previous, fault-tolerant state.
N O T E S
1. Standard operating system services do not require
control during the Active Upgrade process. Select
only services that pertain to your critical applications
(for example, Exchange, SQL, and IIS).
2. The Active Upgrade console never changes the
default Startup Type for a service on the Production
Side. Maintaining the default Startup Type on the
Production Side ensures that a service is always able
to restart on the Production Side if the upgrade
process is aborted or fails.

Download from Www.Somanuals.com. All Manuals Search And Download.
Selecting Event Log Files to Back Up
When you commit an upgrade, the system reestablishes the RDR mirrors of any
system disks by overwriting the Production Side disks (which contain the old version of
your software) with the newer Upgrade Side disks (which contain your newly-upgraded
software). Because the event log files on the Production Side are lost during this
process, you might want to preserve them for future reference. These log files contain
the only record of log messages your live applications generated while the system was
split.
The Log File Backup page allows you to select from all event logs available in the
Windows Event Viewer, including user-created logs.
N O T E S
1. For information about creating a Custom Action that
preserves other files from the Production Side system
disk, see “Configuring Custom Actions” on page 3-12.
2. You must save the log files to an internal data disk or
an external disk. Do not save the files to a system
disk or network share.
3. There is no default directory. You must specify a
directory, otherwise, the Active Upgrade console
displays a warning message.
To preserve event log files
1. Specify a directory in which to save the files by doing one of the following:
• In the Staging Directory dialog box, type the full path name of the directory.
• Click Browse to locate a folder using the Browse for Folder dialog box. Click
a folder and click OK to select it.
2. For each log you want to save, click the log name to highlight it, then click the check
box to the left of the log name to preserve the file.
When you have finished selecting event log files to preserve, you can click Next to
proceed with the next configuration step.

Configuring Custom Actions
Configuring Custom Actions
Use the Custom Actions page to customize the way that the Active Upgrade process
runs in your environment. You can create custom actions to perform the following types
of tasks:
• Specify how a critical application is stopped and started during the upgrade
process.
For example, if you use special executable files to start and stop your applications,
you can use the controls on the Custom Actions page to specify when these
executable files will run during the upgrade process, and, if you have several files,
you can specify the order in which they will run.
• Check if a certain condition exists before starting the upgrade process.
For example, you can write a program to verify that a critical backup has completed,
if the load on the system is acceptable, or if it is a certain time of day before starting
the upgrade process.
• Back up files during the upgrade process.
Any files that are modified on the Production Side system disks while the system
is in split mode are lost during the commit process, when the RDR mirrors are
resynchronized. If applicable, you can write a program to save copies of important
files before you commit an upgrade. For example, you can save a copy of an
application-specific log file that does not appear in the system Event Viewer. (For
information about saving Event Viewer logs, see “Selecting Event Log Files to Back
Up” on page 3-10.)
By default, the Custom Actions page supports executable files that are batch files
(.bat), application files (.exe), or Visual Basic scripts (.vbs). For other types of
executable files, see “Executing Visual Basic Scripts and Other Types of Executable
Files” on page 3-18.
N O T E S
1. Custom actions run consecutively when called. If one
action fails to terminate, it might prevent the next
action from executing, and, ultimately, prevent the
upgrade process from continuing. When you specify
an executable file for a custom action, verify that it
runs successfully outside of the Active Upgrade
process, and ensure that it completes in a timely
manner.
3-12 Express5800/320Fc: Active Upgrade™ User’s Guide
Download from Www.Somanuals.com. All Manuals Search And Download.
Configuring Custom Actions
2. Executable files for custom actions must be located
on a system disk. If a executable file is located on an
external or network disk, the Upgrade Side loses
access to the file while the system is in split mode.
3. For information about writing your own programs for
custom actions, see “Programming Notes for Custom
Actions” on page 3-15.
To configure a custom action
1. On the Custom Actions page, do one of the following:
• Next to File, type the full path name and file name of the executable file you
want to run. (The file must already exist on the system.) For example:
C:\bin\mybatchfile.bat
• Click Browse to locate the executable file using a file browser. Click the file
name in the file browser, then click Open to select the file.
2. Next to Arguments, type any arguments that you need to run with your executable
file.
No arguments are required; however, see “Programming Notes for Custom
Actions” on page 3-15 for information about optionally passing Active Upgrade
environment variables to your executable file.
3. In the drop-down list for Control type, select the option that best describes when
the Active Upgrade console should execute your custom action, as described in
Table 3-3.
Table 3-3. Control Types for Custom Actions
Control Type
Purpose
Start Application
Executes the custom action whenever the Active Upgrade console
needs to start applications. For example, the console needs to restart
applications on the Upgrade Side when you merge the system.
Stop Application
Readiness Check
Executes the custom action whenever the Active Upgrade console
needs to stop applications. For example, the console needs to stop
applications on the Upgrade Side when you split the system. It also
stops applications on the Production Side when you merge the
system.
Executes the custom action once during the readiness check, before
you initiate the Active Upgrade process. This control type allows you
to build your own verifications into the readiness check.

Configuring Custom Actions
Table 3-3. Control Types for Custom Actions (Continued)
Control Type
Purpose
Advanced
Executes the custom action during every step of the Active Upgrade
process, including interim steps such as PrepareSplit and
PrepareMerge, which occur prior to the Split and Merge operations.
This control type allows you to have more precise control over a
custom action. Your executable file runs each time the upgrade
process switches states, but you can write a program with conditional
statements based on Active Upgrade environment variables to specify
exactly when and where particular tasks should be executed. For
example, you can write a conditional statement that triggers only on
the Upgrade Side if the system is in merge mode. See “Using Active
Upgrade Environment Variables” on page 3-16 for more information.
If you have more than one custom action, the Advanced control type
also allows you to control the order in which the custom actions are
executed (step 4).
Backup
Executes the custom action when the system is merged, allowing you
to back up files that were modified on the Production Side system disk
while the system was in split mode (before these files are lost during
the commit process).
4. If you selected the Advanced control type, optionally select an item from the
Timing drop-down list which best describes the order in which you want this
custom action to run with your other custom actions. Table 3-4 describes the timing
options. If the timing does not matter, keep the Default setting.
N O T E
Timing does not affect the order in which custom actions
run with other Active Upgrade tasks. Use this option only
if you want to ensure that one custom action runs before
or after another custom action.
Table 3-4. Timing for the Advanced Control Type
Timing
Default
Early
Purpose
Executes the custom action in the default, consecutive order.
Executes the custom action early in the list of custom actions, before
items marked as Default or Late.
Late
Executes the custom action late in the list of custom actions, after
items marked as Early or Default.

Configuring Custom Actions
Custom actions run consecutively according to their timing options. Subsequent
custom actions do not start until the current custom action terminates.
5. Click Add to accept the custom action. (If the Add button is inactive, ensure that
you typed the File path name and file name correctly. The executable file must exist
to be added.)
You can view the custom actions you have created at the bottom of the Custom
Actions page. If you want to remove a custom action from the list, select it and click
Remove.
When you have finished specifying custom actions to run, or if you have no custom
actions to specify, you can click Next to proceed with the next configuration step.

If you write a program to control a critical application during the upgrade process,
ensure that your program not only stops and starts the application at the appropriate
times, but also disables and enables the default startup mechanism for the application
(for example, the default Startup Type setting in the Services Control Manager or a
startup item in the system registry). If you do not disable the default startup type for an
application, it might interfere with or override your custom action.

Using Active Upgrade Environment Variables
You can optionally use the environment variables specified in Table 3-5 in any program
that you write for a custom action. These environment variables are useful if you want
to write a conditional statement in your program that, for example, runs only on a
particular side of the system or only during a particular stage of the Active Upgrade
process.
Table 3-5. Environment Variables for Custom Actions
Environment Variable
Description
ACTIVE_UPGRADE_SIDE
Describes the side of the system on which the program
is running.
Values: Production, Upgrade
ACTIVE_UPGRADE_STATE
Describes the current upgrade state.
Values: Idle, PrepareSplit, Split, PrepareMerge, Merge,
Commit, Abort
ACTIVE_UPGRADE_REQUEST
Describes the current task that the Active Upgrade
console is executing.
Values: Idle, CheckReadiness, PrepareSplit,
ExecuteSplit, PrepareMerge, ExecuteMerge, Commit,
Abort, Start, Stop, Backup
ACTIVE_UPGRADE_HW_SPLIT Describes whether or not the system is running in split
mode.
Values: Yes, No
By default, these environment variables are available to any child process of the Active
Upgrade console, including executable files for custom actions. However, if necessary,
you can also pass the environment variables to your executable files as arguments.
For example, to pass only the ACTIVE_UPGRADE_SIDE variable to an executable
file, append the following string to the Arguments for the custom action on the Custom
Actions page:
%ACTIVE_UPGRADE_SIDE%

Configuring Custom Actions
To pass multiple variables, add a space between each variable, as follows:
%ACTIVE_UPGRADE_SIDE% %ACTIVE_UPGRADE_REQUEST%

Generating Exit Values
An exit value of 0 indicates that the executable file exited normally. Any other exit value
indicates that there was an error, which prevents the Active Upgrade process from
continuing with the current upgrade request. If this happens, you must correct the
problem and click Retry in the Active Upgrade console to retry the current upgrade
request (which also runs the custom action again). The Active Upgrade process does
not continue until the executable file for your custom action runs successfully.
Related Topics
• “Programming Notes for Custom Actions” on page 3-15
• “Configuring Custom Actions” on page 3-12
Viewing Standard Output and Error Stream
After your program executes, you can view standard output and error output from the
program in the Active Upgrade console, as follows:
1. In the activity log, expand an Execute custom actions node.
(There can be more than one Execute custom actions node, depending on the
types of custom actions you have created. Find the node for the upgrade stage in
which your custom action was set to run.)
2. Double-click a specific custom action to display more information about it.
3. In the detail window, view the output for your program under Status. If necessary,
scroll down in the Status box to see the full output. Or move your cursor over the
Status box to view the output as ToolTip help.
If you save the activity log to a file, you can also view the output in that file. See “Saving
the Activity Log to a File” on page 5-1 for more information.

Configuring Custom Actions
Executing Visual Basic Scripts and Other Types of Executable Files
By default, the File field on the Custom Actions page accepts only batch files (.bat),
application files (.exe), and Visual Basic scripts (.vbs). However, if necessary, you
might be able to run another type of executable file (such as a Perl script) by
implementing the command-line script host for the file.
You can also optionally run the command-line script host for Visual Basic scripts
(cscript.exe) if you need to enable options that are available only in that environment.
For example, to run your Visual Basic script in a command-line script host, do the
following when performing the procedure in “Configuring Custom Actions” on
page 3-12:
• Next to File, type the full path and file name of the command-line script host:
%SystemRoot%\system32\cscript.exe
(%SystemRoot% is an environment variable that automatically inserts your system
root directory, typically C:\WINNT.)
• Next to Arguments, type the full path name and file name of your executable file.
For example:
C:\bin\myvbscript.vbs
If applicable, you can type additional arguments that are specific to your script file or
options that are specific to the session. For example, for a cscript session, you might
want to specify the //T option to control the maximum amount of time your program is
allowed to run:
C:\bin\myvbscript.vbs //T:30
The preceding example would terminate the program and cscript session after 30
seconds. Setting this type of time limit is a useful way of ensuring that your executable
file cannot delay the upgrade process.
For more information about the cscript command, open a Command Prompt session
and enter cscript /?.

Performing the Active Upgrade process can involve the following tasks:
• Performing a readiness check
• Splitting the system
• Merging the System
• Committing the upgrade
• Aborting the upgrade (if necessary)
• Finishing the upgrade
• Viewing Active Upgrade process status
Performing a Readiness Check
Before you can initiate split mode on a system, the system must pass a readiness
check. The readiness check verifies that your system meets the prerequisites for the
Active Upgrade process. For example, the readiness check ensures that:
• The system is currently running in duplex mode.
• The disks you selected as system disks are present and are mirrored with RDR.
• The system contains two properly configured VTM adapters.
• The embedded Ethernet PCI adapters in your system are configured into Ethernet
teams, and each team contains at least one adapter from each physical enclosure.
• The application services you specified for control are currently running, and can be
stopped when necessary.
• The executable file for any custom action is present on the system and ready to run.
To perform a readiness test, do one of the following:
• Click Next on the Upgrade Summary page (if you are using a configuration file).
• Click Active Upgrade on the navigation bar (the readiness test starts automatically
if you have recently opened or changed your configuration).
• Click Retry on the Active Upgrade page.

Splitting the System
Splitting an Express5800/320Fc system divides it into two independently-functioning
systems: the Production Side, which continues to run your applications, and the
Upgrade Side, which you can safely upgrade.
Splitting the system:
• Disables RDR mirroring between the internal disks in each CPU-I⁄ O enclosure.
• Isolates the Upgrade Side from system resources such as the network, any
user-specified application data disks, and any external PCI resources.
• Disables any user-specified applications and services on the Upgrade Side so they
cannot restart if you restart the operating system on the Upgrade Side.
• Queues any ActiveService Network alerts generated on the Upgrade Side until the
system is merged.
You can split a system only if it meets the prerequisites for the Active Upgrade process
and has passed the readiness check.
N O T E S
1. When in split mode, the Upgrade Side has no access
to the network. If you need a network resource to
obtain any software installation packages you intend
to run, transfer the software to the system before you
initiate split mode. Furthermore, put the software on
one of the system disks, because these are the only
disks you can access on the Upgrade Side while the
system is in split mode.
Performing the Upgrade 4-3

Splitting the System
2. Split the system only when you are sitting at the console for your
Express5800/ft series system. The Active Upgrade console
is not supported over remote connections.
C A U T I O N
!
Do not perform any hardware maintenance, including the
removal of either CPU-I⁄ O enclosure, after you have
initiated the Active Upgrade process (by clicking Split).
To split the system
1. Ensure that you have addressed any critical errors or warnings that were indicated
by the readiness check.
2. Exit any non-essential applications.
3. Click Split on the Active Upgrade page.
When the system successfully enters split mode:
• The Active Upgrade console continues to run on the Production Side of the
system.
• The Active Upgrade console switches to the Split System page.
• The upgrade state, reported in the status bar, is Production Side | Split | Ready,
indicating that the system is currently split (and ready to be merged after your
software installation).
Splitting the system should take only a few minutes. The process will time out if it takes
longer than 5 minutes.
N O T E S
1. Throughout the upgrade process, icons appear and
disappear in the system tray as PCI devices, such as
Ethernet PCI adapters, are reconfigured or disabled
for the current upgrade operation. This is normal. Do
not attempt to enable or reconfigure any of these PCI
devices while the upgrade session is in progress.
®

2. If your system is running EMC PowerPath software
for an external storage system, you might experience
a brief delay (10-15 seconds) when the system splits,
as PowerPath reroutes storage operations through
the Production Side.

Splitting the System
If the split process fails the first time, you can click Retry to try again. If the problem
persists, you can click Abort to abort the upgrade process, or see Troubleshooting for
information about resolving the problem.
When the system is split, you can:
• Manage upgrade tasks on the Upgrade Side.
• Manage your applications on the Production Side.
• Verify the Upgrade Side before merging the system.
(To perform upgrade tasks, you must establish a remote connection to the Upgrade
Side, as explained in “Managing Upgrade Tasks on the Upgrade Side” on page 4-5.)
N O T E
After you establish a connection to the Upgrade Side, you
can optionally check the status of your application
services on the Upgrade Side, to verify that they have
been stopped by the Active Upgrade console. See
“Verifying the Status of Application Services” on page 5-2.

Managing Upgrade Tasks on the Upgrade Side
While the system is in split mode, you can perform any of the following upgrade tasks
on the Upgrade Side:
• Run software installation programs (see “Running Software Installation Programs”
on page 4-10, and “Software Upgrade Support” on page 2-1 for restrictions).
• Restart the operating system, if necessary (see “Restarting the Upgrade Side” on
page 4-12).

If necessary, you can also completely abort the upgrade process from the Active
Upgrade console on the Production Side.
Because the Active Upgrade console itself runs on the Production Side of the system,
you need to establish a remote connection to the desktop on the Upgrade Side before
you can complete any of these upgrade tasks, as explained in “Connecting to the
Desktop on the Upgrade Side” on page 4-6.

Connecting to the Desktop on the Upgrade Side
While the system is in split mode, the Active Upgrade console runs on the Production
Side of the system. To perform upgrade tasks, you must establish a remote connection
to the Upgrade Side.
You can access the Upgrade Side using one of two methods:
• Remote KVM
Allows you to control the keyboard, video, and mouse of the Upgrade Side using
the Advanced Video Redirection (AVR) feature of the VTM console. You might
prefer this option if you require access to the BIOS settings and troubleshooting
information that are available in the VTM console.
• Remote Desktop
Allows you to control the keyboard, video and mouse of the Upgrade Side through
the Windows Remote Desktop component. You might prefer this option if you are
more familiar with it, or if it runs faster in your environment.
To use either connection method, click the associated link (Figure 4-1) in the navigation
bar of the Active Upgrade console. For more information, see Related Topics.

Merging the System
Verifying the Upgrade Side Before Merging the System
After you have upgraded or installed software on the Upgrade Side, you can perform
limited testing on the Upgrade Side system disks, as long as your activities do not
require access to the following resources, which are currently unavailable:
• Network
• Internal data disks
• Application data disks
For example, you might want to perform the following tasks before you merge the
system:
• Verify the presence and version number of each software package (see “Verifying
the Status of Installed Software” on page 5-3).
• If possible, verify that you can start the applications you installed or upgraded.
• If possible, configure the settings for any applications you installed or upgraded.
If you are satisfied that everything is working correctly, you can merge the system to
stop your applications on the Production Side and restart them on the Upgrade Side for
final verification.
If there are any problems, you can abort the upgrade to return the system to its original
state. Aborting the upgrade while the system is in split mode does not incur downtime,
because your critical applications are still running on the Production Side.

Merging the System
After you are finished performing upgrade tasks on the Upgrade Side of the system,
you can merge the system to verify your changes before you permanently commit
them.

Merging the System
Merging the system:
• Stops your applications and services on the Production Side.
• Merges system resources so that the network and application data disks become
available to the Upgrade Side.
• Restarts your applications (including the Active Upgrade console) from the
Upgrade Side.
To merge the system
1. Verify that all installation processes are complete, and that you have exited any
installation programs.
2. Optionally, terminate any Remote KVM or Remote Desktop sessions.
N O T E
You can remain logged on to the Upgrade Side if you want
to maintain the current desktop session. After the merge,
you will be using the Upgrade Side desktop.
3. Verify that the upgrade state, as reported in the status bar, is
Production Side | Split | Ready.
If the status is Busy, you must wait for the current task to complete. If it is Broken,
you might need to abort the upgrade.
4. Click Merge.
N O T E
Your screen might flicker and you might briefly lose control
of your keyboard and mouse as the system is merged.
Depending on the complexity of your applications and the upgrade you performed, your
applications should be back up and running in under a minute.
After the merge process completes, the upgrade state is
Fault Tolerant | Merge | Ready, indicating that the system is currently merged and the
upgrade is ready to be committed. You can test your applications to verify that the
upgrade was successful.
If the merge process fails the first time, you can click Retry to try again. If the problem
persists, you can click Abort to abort the upgrade process, or see Troubleshooting for
information about resolving the problem.

Verifying the Upgrade Side Before Committing the Upgrade
After you have merged the system, your critical applications (including the Active
Upgrade console) are running from the software on the Upgrade Side system disks. At
this point, you can test the software you installed and verify the general health of the
system with full access to the system’s resources, including:
• Network resources
•
•
External storage
Application data disks
For example, you might want to perform the following tasks before you commit the
upgrade:
• Verify that all of your critical applications have restarted on the Upgrade Side (see
“Verifying the Status of Application Services” on page 5-2).
• Verify that you have access to your network and application data disks.
• Verify that client systems can reach all of the services that your system provides.
• Verify the presence and version number of each software package (see “Verifying
the Status of Installed Software” on page 5-3).
• Verify that you can start and run any applications that you have installed or
upgraded (if they are not already running).
• Check the configuration settings for your applications and the operating system,
which could have been altered by software installation.
If you are satisfied that everything is working correctly, you can commit the upgrade to
make the changes permanent.
If there are any problems, you can abort the upgrade to return the system to its original
state. However, aborting the upgrade while the system is in merge mode incurs
downtime, because the Active Upgrade console must stop your critical applications on
the Upgrade Side before it can restart them on the Production Side.

Committing the Upgrade
When you are finished testing your applications on the merged system, and you are
satisfied that everything is working correctly, you can commit the upgrade to make it
permanent.
Committing the upgrade:
• Reestablishes the mirror of any internal RDR system disk by overwriting the
original partner disk with its newer, upgraded partner disk.
• Reestablishes the mirror of any internal RDR data disk by overwriting the stale
partner disk with its newer, live partner disk (the disk to which your applications
have been writing data throughout the upgrade process).
• Does not restart your applications, as they are already running on the upgraded
system. There is no additional downtime.
C A U T I O N
!
You cannot abort the upgrade process after you
commit an upgrade because the original state of the
system is lost (overwritten) as a result of completing the
upgrade process. Ensure that your system is working as
expected before clicking Commit.
To commit the upgrade
1. Close all non-essential applications.
2. Verify that the upgrade state, as reported in the status bar, is
Fault Tolerant | Merge | Ready.
3. Click Commit.

You cannot abort the upgrade process after you commit
an upgrade because the original state of the system is lost
(overwritten) as a result of completing the upgrade
process.
When you abort an upgrade, the Active Upgrade console:
• Cancels the current Active Upgrade operation.
• If applicable (if your system is in the merge state), initiates a system restart. It shuts
down the Upgrade Side and restarts the system from the Production Side, which
automatically restarts your applications from your original Production Side system
disks.
• If applicable, reestablishes the mirror of any internal RDR system disk by
overwriting the upgraded partner disk with the original partner disk.
• If applicable, reestablishes the mirror of any internal RDR data disk by overwriting
the stale partner disk with its newer, live partner disk (the disk to which your
applications have been writing data throughout the upgrade process).
• If applicable, brings the Upgrade Side online to enable fault-tolerant, duplex mode.

Verifying If RDR Disks Are Resynchronizing
Verifying If RDR Disks Are Resynchronizing
When you complete or abort the Active Upgrade process, the system reestablishes the
mirrors between the RDR partner disks in each CPU-I⁄ O enclosure. If you intend to
initiate another upgrade process, you must wait for the full resynchronization to
complete before you do so.
You can tell if a disk is resynchronizing by viewing the LEDs on the front panel of the
disk. For information about interpreting the LEDs, see the operation and maintenance
guide for your system.
You can also view the status of your disks using one of the following methods:
• Run a readiness check. On the Active Upgrade page, click Retry. If the disks are
still resynchronizing, the upgrade state is reported as
Fault Tolerant | Idle | Broken and the activity log displays errors indicating that
the disks are not ready.
• View the disks on the Disk Selection page. Any volume that is red is simplexed
(and, thus, probably still resynchronizing). When a disk volume is only green, it is
duplexed and you can start another upgrade. (See “Selecting Disks to Upgrade” on
page 3-5 for more information about disk states on the Disk Selection page.)
• View the disks in ftServer Management Console (ftSMC), using the following
procedure.
To view the status of an RDR virtual disk in ftSMC
1. Open the RDR Utility.
2. Click Logical Disk Information.
3. Click one of the RDR Virtual Disk nodes.
4. Check the value of the Status property, which displays Resync nn% (where nn is
the percentage completed) while the disk is resynchronizing. When the resync
process is finished, the value is None.
Ensure that the value of the Status property for all RDR Virtual Disks is None before
you retry the Active Upgrade process.

Glossary
Glossary-
Active Upgrade technology
A process that allows you to upgrade system software and applications on an
Express5800/320Fc system while its critical applications remain online and
accessible to users. For more information, see the Overview.
application service
A program that runs in the background and performs tasks related to other
programs on the local system or on remote systems. For example, a server may
run an Exchange service, which can process email for local and remote systems.
The Active Upgrade console allows you to specify services that are related to your
applications so that, when necessary, the applications and services may be started
or stopped simultaneously.
See also custom action.
advanced video redirection (AVR) session
See Remote KVM.
call
To declare a program, script, or file that will be referenced by the current file. See
also nesting (for configuration files).
child configuration
A configuration file that is called into a parent configuration file in a nested
configuration.
commit upgrade
The stage of the Active Upgrade process during which the system makes the
upgrade permanent by remirroring the upgraded system disk and the current data
disk with their older partner disks.
You cannot abort the Active Upgrade process after you commit the upgrade,
because the original version of your system is erased as a result of reestablishing
the RDR mirrors.
Glossary-1

Glossary
configuration file
A file that contains all of the settings pertaining to the Active Upgrade process for
your system. You can create multiple configuration files, each for a different type of
upgrade that you regularly perform on your system. You can also use nesting to
incorporate the settings of one configuration file into another configuration file.
critical system resource
A system component, such as a hard disk or network adapter, that is required to
run mission-critical applications.
custom action
A mechanism for controlling your critical applications during the Active Upgrade
process. By specifying executable files and certain parameters in the Active
Upgrade console, you can ensure that your applications are stopped or restarted
at the appropriate times when the system is split or merged.
data disk
An internal RDR disk that is resynchronized from the Production Side to the
Upgrade Side upon completion of the Active Upgrade process.
Data disks are available only on the Production Side while the system is running in
split mode. They typically contain live data (for example, database files and
transaction logs) required by your applications.
A disk that contains active Windows operating system components (boot partition,
paging file) cannot be a data disk (see system disk).
duplex mode (duplexed)
The state of an ftServer system when most or all of its individual components are
paired with redundant partner components that can keep the system operational if
a hardware failure occurs.
It is safe to initiate an Active Upgrade on a duplexed system because redundant
components continue to run your applications during the upgrade process.
element
Redundant segments of an ftServer system that contain components such as
processors, hard drives, PCI slots, and certain I/O ports.
Each system comes with a minimum of two CPU elements and two I/O elements,
usually distributed over two or more enclosures. The elements in an enclosure
operate with each other, or, if necessary, with elements in another enclosure, to
emulate a single logical system.
Glossary-2 Express5800/320Fc: Active Upgrade™ User’s Guide
Download from Www.Somanuals.com. All Manuals Search And Download.
Glossary
enclosure
A physical container that includes at least one CPU element and at least one I/O
element. In a system with more than one physical enclosure, you may be able to
remove or upgrade one enclosure while the other continues to run your
applications uninterrupted.
executable file
A program file, such as a .exe, .bat, or .vbs file, that you can assign to a custom
action.
fault-tolerant mode
Same as duplex mode.
high priority update (hotfix)
Critical update that should be installed as soon as it becomes available.
installation program
A program file that installs a software package.
mandatory system disk
A disk that is automatically marked as a system disk (on the Disk Selection page
of the Active Upgrade console) and cannot be changed to a data disk. A mandatory
system disk contains either boot files or paging files (virtual memory files) that are
currently in use by the running operating system.
In detail, a disk becomes a mandatory system disk if:
• It contains a volume or part of a volume that the operating system identifies as
a system volume.
• It contains a volume or part of a volume that contains an operating system
paging file.
• It contains a volume or a part of a volume that contains a mount point for a
volume that is either a system volume or contains a paging file.
Note that volumes can span multiple disks and that disks can contain multiple
volumes. The operating system defines as a system volume the volume that was
used to perform the initial low level boot of the system and the volume that contains
the Windows directory. These are typically the same volume but they need not be.

Glossary
merge system
The stage of the Active Upgrade process during which the system restarts your
applications on the Upgrade Side.
When the system is in a merged state, it has access to critical system resources,
which you can use to test your applications and verify if the upgrade was
successful.
nesting (nested configuration files)
A method of calling one or more existing configuration files from the configuration
file you are currently editing, so that the settings from the called files will also apply
to the file you are editing. See also child configuration and parent configuration.
parent configuration
A configuration file that calls child configuration files and incorporates their settings
in a nested configuration.
persistent data file
A file that stores permanent records for an application, such as a database file.
Production Side
The side of a split-mode system that continues to run your applications and serve
live users during the upgrade process. See also Upgrade Side.
Remote Desktop Connection
A Microsoft Windows component that allows you to control the keyboard, video and
mouse of a remote system from your local system as though you were sitting at that
system’s console.
You can click the Remote Desktop link in the Active Upgrade console to open a
Remote Desktop Connection to the Upgrade Side of a split system.
Remote KVM
A Web browser-based utility that allows you to control the keyboard, video, and
mouse of a remote system from your local desktop as though you were sitting at
that system’s console. (Remote KVM employs the Advanced Video Redirection
(AVR) feature of the VTM console.) Unlike Remote Desktop Connection, Remote
KVM can control the remote system even when the remote operating system is not
running.
You can click the Remote KVM link in the Active Upgrade console to open an AVR
session to the Upgrade Side of a split system.

service
See application service.
session
One complete Active Upgrade process, from split mode to finish. Or, a remote
connection to the upgrade side of the system, as in a Remote KVM (or AVR)
session.
simplex mode (simplexed)
The state of an ftServer system when one or more of its individual components is
operating without a redundant partner component. If a hardware failure occurs,
system operations may terminate.
You cannot initiate an Active Upgrade on a simplexed system because there are
insufficient system resources to keep the system operational during the upgrade
process.
split mode
The state of an ftServer system when its elements are split into two independent,
simplexed systems — a Production Side and an Upgrade Side.
split system
The stage of the Active Upgrade process during which the system enters split
mode.
Also, a system that is running in split mode.
system disk
An internal RDR disk that is resynchronized from the Upgrade Side to the
Production Side upon completion of the Active Upgrade process.
Only software located on system disks can be upgraded online. System disks are
available on both sides of the system when it is running in split mode. They typically
contain binary files (for example, operating system drivers and application
services) and configuration information (the Windows registry).
A disk that contains active Windows operating system components (boot partition,
paging files) is automatically marked as a mandatory system disk, and cannot be
changed to a data disk. Other disks default to data disks, but can be changed to
system disks per user configuration if they contain only application binaries and
configuration data.
temporary file
A file that stores data only for a short time, such as a cache file.

Glossary
Upgrade Side
The side of a split-mode system on which you can upgrade software. See also
Production Side.
volume
A fixed amount of storage on a hard disk (or spanning many hard disks) that is
defined and managed as a single device in the operating system.
