Product Overview
Key Features
The key features of the storage systems are:
·
·
·
·
·
Dual wide SCSI bus, either single-ended or fast/wide differential
Two redundant fan modules (shipped standard)
Two redundant power modules (one shipped, one optional)
Up to eight 1-inch-high, or four 1.6-inch-high slots
Optimized for high availability
High Availability
The storage systems are optimized for high availability with the following features:
·
·
·
·
·
Dual SCSI bus
Hot pluggable, front-accessible modules
Redundant fan and power modules
Can mirror disks in the same storage system
Can be integrated with mirrored disks in an HP-UX environment with MC/LockManager and
ServiceGuard
·
Can be integrated with diagnostic tools to allow remote monitoring and troubleshooting.
SCSI Buses
The storage system contains two separate wide SCSI buses. One bus is connected to the slots in bay A and
the other bus is connected to the slots in bay B. Each bus can be used independently, or can be connected
together via an external SCSI cable to form one common bus. In a common bus configuration, four 1-inch
disk modules can be installed in each bay for a maximum of eight devices per bus, or two 1.6-inch disk
modules or DDS tape modules can be installed in each bay for a maximum of four devices per bus.
Modular Design
Each storage system contains the following modular components: fans, power supplies, disk drives, and
DDS tape drives. Each component is housed in a plastic module. Each storage system contains two slots
for fan modules, two slots for power modules, and eight 1-inch-high slots for disk modules or DDS tape
modules. Each module is easily removed by pulling out a locking lever, is installed or removed from the
front of the storage system, and can be used in any of the three storage system enclosures.
Fibre Channel (FC) SCSI Multiplexer (MUX) Connection
Fibre channel host connection is available through a Fibre Channel (FC) SCSI Multiplexer (MUX).
Configurations of the FC are detailed in the HP 9000 Enterprise Servers Configuration Guide. For

Product Information
Product Overview
information regarding the Fibre Channel technology, refer to the Fibre Channel SCSI Multiplexer Service
and User Manual, part number A3308-90005.
NOTE! The term hot pluggable refers to modules that can be replaced while the host and
storage system are operating, without disrupting their operation. Not all modules are hot
pluggable, and some modules require the use of command line utilities before the module is
removed, and after the module is replaced. The storage systems do not support installation of
additional disk modules or DDS tape modules while the host and storage system are operating.
Fan Modules
The storage system is shipped with two fan modules, which provide redundant cooling. If one fan fails,
the remaining fan will provide enough cooling capacity for the storage system. Fan modules are hot
pluggable. Failed fan modules should be replaced as soon as possible.
Power Modules
The storage system is shipped with one power module. Two power modules provide redundant power for
the storage system. If one power module fails, the storage system continues operating on one power
module. If two power modules are used, both share the load. Power modules are hot pluggable.
Disk Modules
The storage system can contain any combination of 1-inch-high and 1.6-inch-high disk modules. A 1-inch
disk module occupies one slot in the storage system, and a 1.6-inch disk module occupies two slots. The
disk modules are available with either a single-ended (SE) or fast/wide differential (DF) SCSI interface.
The disk module is enclosed in a plastic module, so SCSI address (ID) jumpers are not accessible. SCSI
ID switches on the rear of the storage system are used to set the disk module SCSI ID.
DDS Tape Module
A 1.6-inch-high, single-ended DDS tape module can also be installed into the storage system. The DDS
tape module occupies two slots. The DDS tape module is enclosed in a plastic module, so tape module
jumpers and SCSI address (ID) jumpers are not accessible. SCSI ID switches on the rear of the storage
system are used to set the DDS tape module SCSI ID.

Installation & Configuration
Setting SCSI ID Switches
Setting SCSI ID Switches
CAUTION! Do not set SCSI ID switches A3, A4, B3, or B4 to ID 0. If their IDs are set to 0,
an over-current condition will occur during the power-on sequence and the power
module will shut down.
CAUTION! All storage modules and host bus adapters (HBAs) must have unique SCSI
IDs. If two or more devices have the same SCSI ID on the SCSI bus, the host will not
recognize those devices.
NOTE! SCSI ID 7 is normally reserved for the host bus adapter (HBA). SCSI IDs 8 through 15
are used only by fast/wide differential (DF) modules.
To set SCSI ID switches for the disk and tape modules:
1. Perform an ioscan(HP-UX) or sysgen(MPE-iX) to determine which SCSI IDs are already in use.
2. Locate the SCSI ID switch for the device (see Figure 10, items 3 through 6 and 9 through 12).
3. Set the SCSI ID switch to an ID number not in use by another device (see Figure 11 and Figure 12):
·
When setting SCSI IDs for 1-inch modules, use the SCSI ID switch that corresponds to the slot
number occupied by the module. For example, if a disk module occupies slot A4, use SCSI ID
switch A4.
·
When setting SCSI IDs for 1.6-inch modules, use the SCSI ID switch that corresponds to the
lowest slot occupied by the module. For example, if a DDS tape module occupies slots A1 and
A2, use SCSI ID switch A1.

Connecting SCSI Cables and Terminators
Connecting SCSI Cables and Terminators
CAUTION! Before connecting SCSI cabling, shut down the host, power-off the host, then
power-off the storage system.
CAUTION! If your host has an HP 28696A adapter, you must have current firmware, or
the differential (DF) disk modules will not be hot pluggable. Contact your HP service
representative to get the current version.
NOTE!
To optimize SCSI bus performance:
·
·
The cable between bus A and bus B must be 0.9 meters in length minimum.
The cable between two A33xxAx storage systems must be 2.5 meters in length minimum.
The storage system contains two separate internal SCSI buses: bus A and bus B (see Figure 10). These
buses are isolated, so two different SCSI interfaces can be supported in the same storage system. Bus A
supports four devices in bay A (slots A1 through A4). Bus B supports four devices in bay B (slots B1
through B4). When a single bus is required, a 0.9-meter SCSI cable can be used to connect bus A and
bus B, forming one bus that supports eight devices.
A SCSI bus consists of the following components. All of these components must be of the same type,
single-ended (SE) or fast/wide differential (DF):
·
·
·
·
a host bus adapter (HBA) card
devices on the bus
SCSI cabling
a SCSI terminator (SF or DF)
Table 2 shows the SCSI bus requirements for the storage system.

Notes:
1. SE = single-ended narrow; DF = fast/wide differential.
2. The total length of SCSI cabling is equal to the equivalent internal cable length (0.9 meter per
internal bus, or 1.0 meter per storage system) plus the external cable length. To connect internal
buses A and B, a bus interconnect cable is required.
3. Depending on the type of interface used, you may not be able to fully load the storage system with 1-
inch storage modules. For example, on a single-ended bus, you must leave one slot empty, since only
seven devices are supported in addition to the HBA. If two storage systems are connected on a
differential bus, eight slots can be filled in the first storage system and seven more slots can be filled
in the second storage system.
4. Each end of the SCSI bus must be terminated. The HBA card is one end of the bus. It includes its own
termination and also provides termination power. The other end of the bus is one of the SCSI
connectors on the rear panel of the storage system. Depending on the configuration, a 68-pin high
density SCSI terminator must be connected to one or both of these connectors. Refer to your host
system documentation for exact terminator specifications.
Connect SCSI cables (see Figure 13 through Figure 15) and SCSI terminators (see Figure 16) to the
storage system in one of the following configurations:
·
Single Bus: Bus B is connected to one host bus adapter (HBA), bus B and bus A are interconnected,
and bus A is terminated with a SCSI terminator (see Figure 13). Two storage systems can be
connected together on a common SCSI bus (see Figure 14).
·
Split Bus: Bus A and bus B are connected to two separate HBAs, each terminated with a SCSI
terminator (see Figure 15). Both buses can have the same SCSI interface or can have different SCSI
interfaces.

Connecting Power Cords
WARNING! The storage system power cords are used as main disconnect devices. To
ensure that the power cords can be disconnected quickly, locate the storage system near
an easily accessible power outlet.
WARNING! To avoid a fire hazard, the ac branch service must be properly current-
protected by either a fuse or a circuit breaker. Use only UL/CSA approved power cord,
SVT type, rated for suitable voltage and current. These power cords have two conductors
and a ground. Failure to use the proper power cord may result in a shock or fire hazard.
NOTE! A fully loaded storage system can run on one power module. If the storage system has
two power modules for redundancy, we recommend that you plug the power cord for each power
module into a separate uninterruptable power supply (UPS). This will allow the storage system to
continue operating if one of the ac power sources fails.
To connect power cords:
Connect power cords to the P1 and P2 ac power connectors on the rear of the storage system (see Figure
10). In a redundant power module configuration, if one power module fails, the other power module will
provide power for the entire storage system.

Clean Light
The DDS tape module monitors the number of errors occurring during read and write operations. If the
number of errors exceeds the error limit, the clean light flashes amber. This condition can be caused by a
hard read or write error, dirty tape heads, or the tape nearing the end of its useful life.
If the clean light flashes amber:
1. Clean the tape heads.
2. Repeat the last operation and see if the clean light flashes again.
3. If the clean light flashes again, copy the data from the old tape onto a new tape then discard the old
tape. The clean light is cleared after you load a cleaning cartridge, or when the DDS tape module is
power cycled.
4. If the clean light flashes after cleaning the tape heads, you should service the DDS tape module.

Loading a DDS Tape Cartridge
Loading a DDS Tape Cartridge
CAUTION! Only cartridges labeled "DDS" should be used in the DDS tape module. Do
not use cartridges labeled "DAT". They will jam in the tape mechanism and damage to the
mechanism will not be covered by the warranty. Also, only apply one label to a DDS tape
cartridge to avoid jamming the tape mechanism.
NOTE! Do not try to force the DDS tape cartridge into the cartridge slot. If it does not load
properly, the cartridge will be ejected after 10 seconds. You can then load the DDS tape
cartridge again.
To load a DDS tape cartridge (see Figure 19):
1. Insert the DDS tape cartridge squarely into the cartridge slot in the direction of the embossed arrow
on top of the cartridge.
2. Gently push the DDS tape cartridge into the cartridge slot until the autoloading mechanism takes the
cartridge. The load sequence takes about 20 seconds. During the load sequence, the tape light flashes
green. When the load sequence has completed, the tape light will turn steady green.

Unloading a DDS Tape Cartridge
Unloading a DDS Tape Cartridge
To unload a DDS tape cartridge:
Press the cartridge unload button. This starts the unload sequence which winds the tape to the beginning,
unthreads the tape, and ejects the cartridge. The unload sequence takes about 25 seconds for a write-
enabled DDS tape cartridge and 10 seconds for a write-protected DDS tape cartridge. During the unload
sequence, the tape light flashes green.
Forcing DDS Tape Cartridge Ejection
CAUTION! You may lose data if you force the ejection of a DDS tape cartridge. Also, the
tape may not be formatted during a forced ejection because the end-of-data (EOD) area
may not have been written on the tape.
If you press the cartridge unload button when the DDS tape module is busy, it may take some time to
respond because it will finish the operation it is performing first. This ensures that the operation is
terminated in a controlled manner and no data is lost. However, you may need to unload a DDS tape
cartridge immediately, even if you risk losing data.
To force DDS tape cartridge ejection, perform one of the following:
·
·
Press the cartridge unload button three times within a five-minute period.
Hold the cartridge unload button down for at least five seconds.
Following either of these actions, a 35-second delay occurs, starting from the first time the cartridge
unload button is pressed. Then, the tape is unthreaded, the cartridge is ejected, and the DDS tape module
is reset as though the power had been cycled.

Controlling Data Compression
Controlling Data Compression
The DDS tape module is shipped with the following default data compression parameters:
·
·
Data compression is enabled at power-on.
Host control of data compression is enabled after power-on.
After the DDS tape module is powered-on, the host can control data compression via device files on HP-
UX and MPE operating systems.
Care of DDS Tape Cartridges
Handling DDS Tape Cartridges
The following precautions will ensure the data integrity and long life of DDS tape cartridges:
·
·
Always store the cartridge in its protective case. Do not drop it or handle it roughly.
Always keep the cartridge in a clean environment. Do not expose it to dirt, moisture, or high
humidity.
·
·
·
Operate the cartridge at temperatures between +5° and +45° C (4l° to -104° F). After moving it from
one temperature extreme to another, allow it to stabilize for at least two hours before using.
Do not place the cartridge in direct sunlight or in places where magnetic fields are present (under
telephones or near transformers).
Do not place a label outside the recessed area on the cartridge. Doing so may cause interference with
the tape loading mechanism. Write on the label before adhering the label to the cartridge. Always
remove the old labels before adhering new ones.
·
·
·
·
Do not touch the tape, or attempt to clean the tape path or tape guides inside the cartridge.
Rewind the tape fully before removing the cartridge for storage.
Do not use excessive force when inserting or removing the cartridge from the module.
Use only data grade DDS tape cartridges, marked DDS-3, DDS-2, or DDS-1. Always label the
cartridge and record the number of uses. Discard the cartridge after 100 uses.
·
Do not use a cartridge beyond its useful life.

Backup Routines
Storing DDS Tape Cartridges
DDS tape cartridges can be stored for a period of 10 years without loss of data. You should give each DDS
tape cartridge in storage a full pass in the tape module at least once a year to prevent the tape media from
sticking to itself. Store cartridges in a cool, dry environment.
Backup Routines
Your backup routine depends on how frequently the data changes, how extensive the changes are, and
how valuable the data is. It is essential that you follow a routine, so data backup is regular and trouble-
free. The following three models present routines which are commonly used. In each model, a "set" of
DDS tape cartridges is the smallest number of cartridges that will hold a full or partial backup. Keep a
record of the number of times each set is used, so a set can be replaced when its recommended write life
(100 insertions) is reached. The replaced set can still be kept for read-only use, but should not be used for
writing.
Model 1: Daily Backup
Number of cartridges needed: 1 set for full backup
This is the simplest backup model. All of your data is backed up onto a single set of cartridges at the end
of each work day. If data is lost, it is simply restored from the previous day's backup. It is the least secure
backup model because if the cartridge is lost, destroyed, or damaged, the data is lost forever.
Model 2: Weekly Rotation with Daily Backup
Number of cartridges needed: 2 sets for full backup
4 sets for partial backup
In this model, you perform a full backup every Friday, and a partial backup on Monday, Tuesday,
Wednesday, and Thursday. Partial backups are made only on those files that have changed since the
previous backup.
Two sets of cartridges, A and B, are used in rotation for the weekly full backups. On the first Friday, you
make a full image copy of your disks on set A. On the second Friday, use set B for a full backup. On the
third Friday, use set A again. This way, there are always two generations of full backup in existence. Store
the sets off-site, preferably in a fire-proof safe.
Four sets of cartridges are used for the daily backups, one set for each day. Because only changed files are
saved, these backups are very quick.

DDS Tape Module
Backup Routines
Model 3: Monthly and Weekly Rotation with Daily Backup
Number of cartridges needed: 6 sets for full backup
4 sets for partial backup
The backup model which offers optimum data protection uses six full backup sets (three monthly and
three weekly), and four sets for daily partial backups. This model is recommended if you compile large
quantities of data where loss would be disastrous. It also provides the best method of securing data from
software viruses.
The four sets of cartridges for daily partial backup are labeled Monday, Tuesday, Wednesday, and
Thursday, as in model 2.
Three sets of cartridges are used in rotation for a weekly full backup on Fridays. Two of these sets are
stored off-site. After a full backup is made on Friday, the set of cartridges is taken off-site and exchanged
for the oldest backup set in storage. Next Friday, the backup is made using this oldest set of cartridges. In
this way, at any moment, three generations of a full weekly backup exist; the two most recent are off-site,
and the oldest is on-site ready for the next backup.
The final three sets of cartridges are used for a full backup on the first working day of each month, again
in rotation. This is in addition to the usual backup that would be made that day, so the normal routine is
maintained. As with the weekly cartridges, the monthly sets should be stored off-site.

Cleaning Tape Heads
CAUTION! Only use the HP 92283K Cleaning Cartridge to clean the tape heads. Do not
use cotton swabs or other tools to clean the heads.
Table 4 shows the proper intervals for cleaning the tape heads in the DDS tape module. You should also
clean the tape heads if the clean light flashes. Once your backup routine has been established, you should
know how many DDS tape cartridges are used each day. Using Table 4, you can estimate how often the
heads will need cleaning and build the cleaning operation into the backup routine.

1. Slide the cleaning cartridge into the cartridge slot. The cartridge is automatically loaded and the
heads are cleaned. At the end of the cleaning cycle, the cleaning cartridge is automatically ejected.
Note the date on the cartridge label so you know how many times it has been used.
2. After the cleaning cartridge is ejected, write the date on the cartridge label This record tells you how
many times the cleaning cartridge has been used. Discard the cleaning cartridge after it has been used

Troubleshooting Procedures
This section contains troubleshooting procedures for the storage systems.
SCSI Bus Troubleshooting Procedure
If the host cannot access any of the devices connected to the SCSI bus, check the following:
1. Check SCSI cables for loose connections and bent pins.
2. Check SCSI terminator connections. A differential terminator on a single-ended bus or a single-ended
terminator on a differential bus will cause the bus to hang. If a terminator is missing, storage system
modules may not pass power-on self-test.
3. Check the SCSI ID switches for conflicting SCSI ID numbers.
4. Check the host bus adapter to see if it includes on-board termination and termination power, or if they
must be supplied externally.
5. Reseat all storage modules.
If there is a SCSI bus problem with a disk module, see Table 10.

Troubleshooting & Diagnostics
Troubleshooting Procedures
Fan Module Troubleshooting Procedure
CAUTION! To maintain proper cooling within the storage system, a failed fan module
must remain in the fan slot until a replacement fan module is installed. A missing fan
module will cause the storage system to overheat and power off.
NOTE! The storage system is designed to operate with two fan modules, regardless of the
number of storage modules installed.
If a fan module fails (see Table 6), check the following:
1. An amber status light indicates the fan speed is too slow, or the fan has stopped blowing air.
2. If both fan modules fail, the power modules will automatically power off in 3 to 7 seconds to avoid
overheating. A SCSI bus reset will occur at this time.
Power Module Troubleshooting Procedures
CAUTION! The following conditions will cause a power module to power off in 3 to 7
seconds: (1) two failed fan modules, (2) a power supply internal fan failure or other
internal component failure, or (3) an over-current condition caused by a faulty storage
system module, a device in one of the four upper slots set to SCSI ID 0, or using an
unsupported device with a high current rating.
Each power module contains a power supply with an internal fan for cooling. Two power modules
(redundant configuration) use active current sharing to share the power load equally. If one power module
fails or is removed, or if one of the ac power cords is accidentally removed, the other power module takes
over the entire power load without interruption.

NOTE! Power cycle the storage system after performing each step in this procedure.
If the storage system contains one power module and a power supply fault occurs when installing
storage modules, perform the following steps:
1. If any storage module in the four upper slots is set to the same SCSI ID number as a storage module
in the four lower slots, change the SCSI ID to a unique number.
2. Remove all storage modules.
3. Install the storage modules one at a time until a power supply fault occurs.
4. Remove all storage modules except the last one installed.
5. If a power supply fault occurs again, replace the storage module.
6. If a power supply fault occurs after replacing the storage module, replace the power module.

CAUTION! There should be no bus activity when these steps are performed. The storage
system should be offline.
If the storage system contains two power modules and two fan modules and two power supply faults
occur, follow these steps:
1. Cycle storage system power.
2. After power-on, the power module status lights will be amber.
·
·
If both fan module status lights do not turn green before they turn off, replace both fan modules.
If at least one fan status light turns green after power-on, either a power module has failed or an
over-current condition exists. Follow the steps under "One Power Module/One Fault”.
DDS Tape Module Troubleshooting Procedure
If a DDS tape module failure occurs, see Table 9.
Disk Module Troubleshooting Procedure
If a disk module failure occurs, check the following:
1. A solid green status light at any time other than during a self-test indicates a drive fault. A flashing or
pulsing green status light indicates read/write activity.
2. Termination problems can prevent successful completion of a drive module self-test. Verify there are
no termination problems on the SCSI bus (see "SCSI Bus Troubleshooting Procedure").
3. Solve the problem using the appropriate procedure. If the disk module needs to be replaced, see
Figure 29. DF Disk Module Replacement Decision Flowchart”.

Module Replacement Procedures
The following procedures describe how to replace the storage system modules.
NOTE! The term hot pluggable, refers to modules that can be replaced while the host and
storage system are operating. Not all modules are hot pluggable, and some modules require the
use of command line utilities before removal and after replacement. See Table 1 in Chapter 2 for
HP system support of hot pluggable modules.
Fan Module Replacement Procedure
WARNING! You can only replace one fan module at a time. Do not remove a failed fan
module from the storage system until the replacement fan module is ready to be installed.
Both fan modules must be installed for proper air flow and cooling.
NOTE! You can replace a fan module while the host and the storage system are operating.
To replace a fan module:
1. Remove the fan module from the storage system (see Figure 24).
2. Install a new fan module into the storage system (see Figure 25).

Power Module Replacement Procedure
CAUTION! The power module is hot pluggable only if a second power module is present
and operating. If you remove the only power module in the storage system, the storage
system and all modules will lose power.
NOTE! If there are two power modules in the storage system, each will share the power load. If
one power module fails or is removed, or if one of the ac power cords is removed, the other
power module will take over the entire power load without interruption.
NOTE! You can replace a power module while the host and the storage system are operating.
To replace a power module:
1. Remove the power module from the storage system (see Figure 26).
2. Install the new power module into the storage system (see Figure 6 in Chapter 2).

DF Disk Module Replacement Requirements
To replace a disk module while the host is operating, all of the following conditions must be met:
·
·
All patches must be loaded by an HP service representative or customer engineer (CE).
All of the extents of the replaced disk that are in use must belong to mirrored logical volumes that
were created with the strict (-s)option.
·
You must have a current volume group configuration backup file. In version 10.x, the backup is
created by default each time an LVM command changes the LVM configuration. The default backup
file path name is: /etc/lvmconf/base_vg_name.conf. In version 9.x, the backup is a manual
process.
·
The replacement disk module must be of the same or greater capacity as the module being replaced.
NOTE! HP uses different manufacturers for disk modules having the same product number.
The manual hot plug procedure will not update the disk module internal information to that of the
replaced disk. A replacement disk module must have the same capacity and block size as the
defective disk module because it has the same product number. The only string that can be
different is the one specifying the vendor name. This will not affect the behavior of the LVM. If
you want to update the manufacturer's name, the disk's volume group must be deactivated and
reactivated.
If the conditions listed above cannot be met, contact your HP service representative for help.

Troubleshooting & Diagnostics
Module Replacement Procedures
If the conditions above are met, you can replace the DF disk module while the host is operating. To know
which replacement and recovery procedure to use, you must:
1. Determine if the volume group is active. See “DF Disk Module - Is the Volume Group or Physical
Volume Group Active? (HP 9000 Series 800 with Strict Mirroring)”.
·
If the volume group is active, determine if the physical volume is attached. See “DF Disk Module
- Is the Physical Volume Attached? (HP 9000 Series 800 with Strict Mirroring)”.
·
If the volume group is not active, follow the procedure under “DF Disk Module
Replacement/Recovery Procedure for Unattached Physical Volumes (HP 9000 Series 800 with
Strict Mirroring)”.
2. Determine if the physical volume (replaced disk module) is attached.
·
If the physical volume (replaced disk module) is attached, follow the procedure under “DF Disk
Module Replacement/Recovery Procedure for Attached Physical Volumes (HP 9000 Series 800
with Strict Mirroring)”.
·
If the physical volume is not attached, follow the procedure under “DF Disk Module
Replacement/Recovery Procedure for Unattached Physical Volumes (HP 9000 Series 800 with
Strict Mirroring)”.
Example of a Disk Module Failure
Use the example in Table 12 of a disk module failure to see the types of messages the host may display
while using LVM utility commands. The DF replacement/recovery procedures base their example
messages on the hardware addresses or device files shown below.

DF Disk Module Replacement/Recovery Procedure for Attached Physical Volumes (HP
9000 Series 800 with Strict Mirroring)
Before you begin, review the requirements under “DF Disk Module Replacement Requirements” and
ensure they are met.
Use the following commands to reduce any logical volumes that have mirror copies on the faulty disk
module so they no longer mirror onto that disk module. If the host fails during a process, the recovery
process is listed at the end of each step.
NOTE! This procedure will use the lvreducecommand to remove mirrors whose extents are
on the defective disk. Once the disk has been replaced, use the lvextendcommand to re-
create the mirrors' extents on the new disk.
NOTE! Mirrors which span several disks may not have their extents placed on the disks as they
were before. For cases where the original mirror layout needs to be preserved, the operator
should consider deactivating the volume group with the vgchangecommand and following the
steps in "DF Disk Module Replacement/Recovery Procedure for Unattached Physical Volumes
(HP 9000 Series 800 with Strict Mirroring)".
Step 1
The -A noption is effective only in HP-UX release 10.01 and later and is not required for HP-UX release
9.04.
For one-way mirroring:
# lvreduce -m <one less than num_mirror> -A n <LV name> <physical volume path>
or, for two-way mirroring:
# lvreduce -m <one less than num_mirror> -A n <LV name> <physical volume path>
If you follow the example under “Example of a Disk Module Failure”, the host will display:
# lvreduce -m <one less than num_mirror> -A n /dev/vg00/lvol4 /dev/dsk/c2t4d0
# lvreduce -m <one less than num_mirror> -A n /dev/vg00/lvol5 /dev/dsk/c2t4d0

Troubleshooting & Diagnostics
Module Replacement Procedures
If the host fails during Step 1
If the host failed during an lvreducecommand, you should execute an lvdisplaycommand to
determine if the command succeeded. If the command did not succeed, the command should be executed
again.
You should perform any other lvreducecommands that had not been executed before the system failure,
then proceed.
NOTE! An important side effect of the lvreducecommands is that the LVM configuration
backup file used by the vgcfgrestorecommand in step 1 is updated. If this hot plug procedure
is being performed now on another host system and there was no need to execute any
lvreducecommands, then the configuration file has not been updated. However, the LVM
configuration is correct on the physical volumes, so the configuration file can be updated with the
vgcfbackupcommand.
Step 2
a. Replace the disk module if you have not done so already.
b. Perform an ioscanon the new disk module to ensure that it is accessible and also, as a double check,
that it is a proper replacement.
If you follow the example under “Example of a Disk Module Failure”, the host will display:
# ioscan /dev/dsk/c2t4d0
HP uses different manufacturers for disks having the same product number. The manual hot plug
procedure will not update the disk module’s internal information to that of the replaced disk.
Replacement disks must have the same capacity and block size as the defective disk because they have the
same product number. The only field that could be incorrect is the string specifying the vendor's name.
This will not affect the behavior of the LVM. If you want to update the manufacturer's name, the disk's
volume group must be deactivated and reactivated.
Step 3
Use the following commands to restore the LVM configuration/headers to the replaced disk modules from
your backup of the LVM configuration:
# vgcfgrestore -n <volume group name> <physical volume path>
For example, the host will display:
# vgcfgrestore -n /dev/vg00 /dev/rdsk/c2t4d0
If the host fails during Step 3
Repeat step 3 to ensure all the configuration data is written to the new disk.

Step 6
Use the lvextendcommand to transfer the mirrors back on to the replaced disk. This will take some
time because it copies all of the data from the original copy of the data to the mirrored extents. The logical
volumes are still accessible to users’ applications during this command for two-way mirroring:
# lvextend -m <one greater than num_mirror> <LV name> physical volume path
or for three-way mirroring:
# lvextend -m <one greater than num_mirrors> <LV name> physical volume path

specific data that further defines the nature of the CHECK CONDITION status.
The Sense Key Specific field is defined by this specification when the value of the SKSV bit is one. The definition of
this field is determined by the value of the Sense Key field. This field is reserved for sense keys not described in
. If the Sense Key field is set to ILLEGAL REQUEST (5h) and the SKSV bit is set to 1, the Sense Key

A command data C/D bit of one indicates that the illegal parameter is in the command descriptor block. A C/D bit of
zero indicates that the illegal parameter is in the data parameters sent by the initiator during the DATA OUT phase.
A BPV (Bit Pointer Valid) bit of zero indicates that the value in the bit pointer field is not valid. A BPV bit of one
indicates that the Bit Pointer field specifies the bit of the byte designated by the field pointer that is in error. When a
multiple-bit fields in error, the Bit Pointer field will point to the most significant bit of the field.
The Field Pointer field indicates the byte of the command descriptor block or of the parameter data that was in error.
Bytes are numbered starting from zero, as shown in the tables describing the commands and parameters. When a
multiple-byte field is in error, the pointer will point to the most significant byte of the field.
If a sense key is RECOVERED ERROR (1h), HARDWARE ERROR (4h), or MEDIUM ERROR (3h), and if the
SKSV bit is one, the Sense Key Specific field is defined as shown in Table 12. These fields identify the actual

Troubleshooting & Diagnostics
Diagnostic Information
SKSV: 0 indicates the Sense Key Specific Bytes (bytes 15 through 17) are invalid. The C/D, BPV, and Bit Pointer
fields will be zero. The top byte of the Field Pointer will be zero, and the bottom byte will contain a product-specific
error code.
1 indicates the Sense Key Specific Bytes are valid. This will only happen when the bytes assume the role of Field
Pointer Bytes as defined by ANSI. This occurs when an Illegal Field check detects an error in a command descriptor
block or a Parameter List check detects an error in a command parameter list.
C/D: Command Data is only valid if the SKSV flag is set. 0 indicates the Field Pointer information applies to the
parameter list for the command. 1 indicates the Field Pointer information applies to command descriptor block.
BPV: 0 indicates the Bit Pointer field is invalid. 1 indicates the Bit Pointer field is valid. If the SKSV bit is set then
the BPV bit must be set also.
Bit Pointer: Identifies the bit position of the field in error, whether it is a command descriptor or a command
parameter list field. Only valid when the SKSV flag is set.
Field Pointer/Drive Error Code: If SKSV is set, this field identifies in which byte of the command descriptor or
parameter list an error was detected. Note that the drive scans from byte 0 bit 7 of a command or parameter list
through to byte n bit 0. The field and bit pointers are set to point to the most significant bit of the field that is in error.
If SKSV is not set, the top byte of this field will be zero. The bottom byte contains the drive error code associated
with the failure of the previous command, or zero in the case of no failure and no appropriate error code.
CLN: 0 indicates the drive is OK. 1 indicates the drive requires cleaning.

SCSI Bus Reset Switch
CAUTION! Changing the default factory settings on the SCSI bus reset switch may cause
operating system conflicts for the host computer. The switch is covered with a label that
states “Factory Set Only”.
NOTE! A SCSI reset is a high priority interrupt. The SCSI bus reset option is used when the
host controller or software requires a SCSI reset to be sent as notification of device removal or
power shutdown.
The default setting for the SCSI bus reset switch is all switch segments enabled. The switch is enabled
when the host controller or software requires a SCSI reset to be sent as notification of disk removal or
power shutdown.
The SCSI bus reset switch is visible on the rackmount rear panel (see Figure 36, item 1). To locate the
switch on the deskside rear panel, remove the two T15 screws (see Figure 37, item 2), then remove the
rear panel (see Figure 37, item 3) to expose the switch (see Figure 37, item 1). Figure 38 shows the switch
segments on the SCSI bus reset switch and Table 23 shows the switch functions.
NOTE! Even when bus A and bus B are connected to form one bus, the SCSI bus reset
switches function independently.
