Chapter 1 Introduction  
How the TC2201 Works  
• Power and Fault (Pwr)—This bi-color LED is green to show that power  
is currently active and is continuously amber-colored to show that  
the TC2201 detects a fault condition in the TC2201.  
• iSCSI (Link/Act)—When lit green, the right indicator signifies a good  
iSCSI link on the port. When lit green, the left indicator signifies iSCSI  
port activity.  
• SCSI Bus (0, 1)—When lit, these green indicators signify SCSI activity  
on the bus corresponding to the number of the indicator.  
• Ethernet (Link/Act)—When lit green, the right indicator signifies a  
good Ethernet link on this management port. When lit green, the left  
indicator signifies Ethernet port activity on this management port.  
How the TC2201 Works  
1
The TC2201 is a router that translates the iSCSI protocol to and from the  
SCSI Protocol—transparently transferring commands, data, and status  
information—so that devices and hosts can communicate with each other.  
Interconnection is provided between two SCSI buses and one or two  
iSCSI networks, also making use of iSCSI’s ability to encapsulate SCSI  
protocol packets.  
Processing SCSI Information  
1
The following section describes how the TC2201 processes SCSI  
information when attached to iSCSI hosts. Figure 3 illustrates steps 1  
through 5 of the process.  
1 An iSCSI host issues a command. The iSCSI host encapsulates the  
command in the iSCSI protocol and sends the packet to the TC2201.  
2 The iSCSI controller in the TC2201 receives the packet, interprets the  
iSCSI information, and places the packet in buffer memory.  
3 The TC2201’s processor interprets the information and programs a  
SCSI controller to process the transaction.

Chapter 1 Introduction  
Processing SCSI Information  
4 The SCSI controller sends the command to the SCSI device (target).  
5 The SCSI target interprets the command and executes it.

buffers (see figure 4).  
7 Response information flows from the SCSI target back to the iSCSI  
host (see figure 4).

Chapter 1 Introduction  
TC2201 Benefits  
TC2201 Benefits  
1
The Quantum TC2201 is designed to connect SCSI devices into an iSCSI  
network. The Quantum TC2201 is neatly packaged in a 1U form factor  
with two 1 Gb/s iSCSI ports and two LVD/SE SCSI buses. SCSI buses  
automatically negotiate for Fast, Narrow, Wide, and up to Ultra160 SCSI.  
External throughput is up to 200 MB/s  
bi-directional per iSCSI port (or 100 MB/s one way per iSCSI port), or up  
to a total of 400 MB/s bi-directional for both ports.  
Enterprise Class  
Performance  
The TC2201 offers enterprise class performance with memory buffer  
1 bandwidth exceeding 1 Gb/s and delivering end-to-end throughput of  
up to 400 MB/s bi-directional for both ports (or 200 MB/s each way for  
both ports together). The TC2201 performs fast tape reads and writes,  
which enables it to handle larger data sets while completing backup and  
restore tasks within a smaller time frame.  
SAN Management  
Reduction  
The Quantum TC2201 is significantly easier to install than other routers  
1 due to the “store-and-forward” configuration feature and the Visual  
Manager (VM) software. “Store-and-forward” allows configuration files  
and TC2201 operational settings to be saved and copied to other like  
routers, reducing redundant setup tasks. Using VM, service professionals  
and end users can configure a TC2201 with simple “point and click”  
choices on a graphical representation of the TC2201.  
Add Intelligence to SCSI  
Storage  
The TC2201 has many features that provide intelligence to SCSI devices  
1 and help manage SAN configurations, performance and reliability. A  
short list includes Visual Manager, dynamic storage allocation (i.e. map  
activation without reboot), SCSI target reset, custom mapping, and access  
controls (LUN masking and management). These features of the TC2201  
provide customers with a high level of storage functionality for high  
performance backup and recovery, reliability, security and manageability  
in their nearline storage solutions.

• DNS Domain is the domain name used by the DNS server. For  
example, a domain name could appear similar to  
“server.company.com”.  
• DHCP enables/disables support for Dynamic Host Configuration  
Protocol (DHCP). When enabled, the TC2201 will retrieve a dynamic  
IP address from a DHCP server located on the Ethernet network that  
the TC2201 is connected to. The default setting is Enabled. If DHCP is  
changed from Disabled to Enabled, it is necessary to reboot the  
TC2201 before an IP address will be requested from the DHCP server.  
After the TC2201 finishes rebooting, the QVM session will have to be  
restarted. The TC2201's IP address will be different than the former  
non-DHCP IP address.  
Note: To use the DHCP feature, a DHCP server must be operational  
on the Ethernet network connected to the TC2201. If the DHCP  
feature is used when there is no DHCP server, the standard for  
DHCP requires that the TC2201 wait three minutes for a  
response from a DHCP server before timing out. During this  
period, the TC2201 menus and functions will not be accessible.  
A DHCP server may allow the setup of a lease reservation for an IP  
address if provided with the MAC address of the TC2201. This forces  
the DHCP server to always provide the same IP address to the  
TC2201. This setup is useful for remote management of the TC2201  
via Telnet or Visual Manager. Because the method of setting up a  
lease reservation varies depending on the DHCP server, it is  
recommended to contact your Network Administrator for assistance.  
• Override Settings are provided to enhance inter operability with some  
devices that require special consideration during setup of the TC2201.  
Access to the Overrides Settings is reserved for authorized Quantum  
technicians. Selecting the Go button opens a login prompt for which  
an authorized technician will have the appropriate user name and  
password.

• Current MAC address is the current Media Access Control (MAC)  
address configured for the TC2201. The MAC address is a hardware  
address that uniquely identifies each physical node on an Ethernet  
network. While the MAC address can be changed, it is highly  
recommended not to change this address.  
• Original Factory MAC address is the MAC address assigned by the  
hardware manufacturer to the Ethernet adapter in the hardware. The  
TC2201 comes initialized with this assigned MAC address.  
• Ethernet MTU Size is the Maximum Transmission Unit (MTU) for  
Ethernet. This setting can be configured for 1500 or 9000 byte frames.  
The Ethernet Management port is permanently set to 1500 and cannot  
be changed. The default setting for the iSCSI ports is also 1500 but a  
value of 9000 can be configured for jumbo frame support for iSCSI  
frames.

• Discovery enables/disables device discovery on this SCSI bus. The  
default setting is Enabled.  
• Discovery Delay is the time in seconds that the TC2201 waits after a  
power-up or reboot process (which typically takes approximately 2  
minutes) before starting to discover SCSI devices. Quantum  
recommends you set the value to at least 2 seconds to ensure all SCSI  
devices complete their individual power-ups. However, the user  
should be aware this delay is added to the time it takes for the  
TC2201 to reboot and for QVM to be active again. The default setting  
is 2 seconds.  
• Bus Reset on Boot enables/disables automatic discovery of SCSI  
devices after an initial power up or reboot of the TC2201. The default

compatibility issues in mixed vendor environments, where, for  
example, there may be a device that cannot handle automatic  
negotiation of the bus speed, or possibly where there is a device that  
does negotiate to use Ultra SCSI-3 but somehow cannot actually

Buffered Tape Writes can be enabled or disabled. The default setting is  
enabled. Buffered Tape Writes is an option designed to enhance system  
performance. By returning status on consecutive write commands prior  
to the tape device receiving data, Buffered Tape Writes remove the  
latency of waiting for responses from the tape device. In the event that  
data does not transfer correctly for any reason, the router will return a  
check condition on a subsequent command.Commands other than  
Write(6) are not issued until status is received for any pending write.  
Also, status is not returned until the device completes the command. For  
instance, when a synchronizing command is sent to a drive, such as  
sending a Write File mark, a good status means all prior commands have  
been successfully completed and data has been successfully written to the  
medium. This is appropriate for such tasks as file backup/restore.  
Note: If an application requires confirmation of individual blocks  
being written to the medium, such as audit trail tapes or log  
tapes, this option should be disabled.

Caution: Before activating any port mapping changes, it is strongly  
recommended that the user verify there are not any  
command or data operations occurring in conjunction  
with devices affected by the mapping changes. For  
example, deleting a LUN or device from a map may  
disrupt I/O transfers with that device. It is the user’s

3Troubleshooting  
Various problems can arise when configuring and using the  
TC2201. This section is provided to help guide the user through  
some of the basic methods of identifying faults in the setup and  
configuration of the unit.  
Most problems are found in the initial installation. In general, it is  
wise to check all connections and review the configuration before  
proceeding with further trouble analysis. Simplify the  
installation if possible, reducing it to the most basic configuration  
then adding elements one at a time and verifying the operation at  
each step.  
Indicators

The TC2201 is equipped with rear panel LED indicators for  
monitoring overall unit status (see figure 44).

Power/fault  
iSCSI Activity  
SCSI Activity for Bus 0 SCSI Activity for Bus 1  
The LED functionality of the TC2201 is detailed below:  
• Power and Fault (Pwr)—This indicator is a bi-color LED. When green,  
this indicator shows that power is currently active. Lack of power  
indication suggests that the unit is turned off, a problem with the  
power supplied to the unit, or an internal problem with the unit.  
When this indicator is amber, this indicator shows that the TC2201  
detects a fault condition. Faults can occur as a result of Power On Self  
Test (POST) failure or operational failures. It is normal for this  
indicator to flash on when the unit is powered up or reset. If the fault  
indicator stays lit, contact your product support representative.  
• iSCSI (Lnk/Act)—When lit green, the upper indicator signifies a good  
iSCSI link on the port. When lit green, the lower indicator signifies  
iSCSI port activity. If the Link indicator fails to light at all, or if the  
Activity indicator stays continually lit without corresponding SCSI  
bus activity, there may be a problem with the iSCSI configuration.  
Verify the iSCSI configuration.  
• SCSI Bus (0, 1)—When lit, these green indicators signify SCSI activity  
on the bus corresponding to the number of the indicator. Activity  
should be indicated only occur briefly during power up or  
configuration, and relatively often when the unit is transferring data.  
If an Activity indicator stays continually lit without corresponding  
target device activity, there may be a problem with the SCSI bus  
configuration. Verify the SCSI bus configuration.  
• Ethernet (10/100)—When lit, these green indicators signify Ethernet  
link status and activity. If either of these indicators fail to flicker, or  
stay continuously lit, there may be a problem with the network  
connection or configuration. Verify the network connection and  
configuration. The port must be connected to a 10/100BaseT Ethernet  
network to function properly.

Serial Port Problems  
3 If you experience trouble communicating with the serial port, verify the  
configuration of the host terminal or terminal emulation program. The  
TC2201 requires the baud rate to be set correctly,  
8 data bits, 1 stop bit, and no parity. Flow control should be set to none or  
XON/XOFF, and may cause problems if set to ‘hardware’. Some terminal  
programs may not support baud rates higher than 19200, so a lower baud  
rate may be required. If problems persist, you may want to check the  
cabling or try a different host. Be sure the Scroll Lock key on the keyboard  
of the host computer is not enabled. If a valid Ethernet IP address is  
configured, serial configuration settings can also be set via telnet.  
Verify SCSI Bus  
Configuration  
Problems with SCSI bus configuration are common. Basic operation of a  
3 SCSI bus can be checked by using the configuration menu to view  
attached SCSI devices. Conditions to look for include:  
• Termination—Problems with termination can cause intermittent or  
hard failure. A SCSI bus must be terminated on both ends, and only  
both ends. Termination issues when both narrow and wide devices  
are on the same bus are common. Check to make sure that there are  
no loose terminators. All terminators should be firmly attached.  
• Bus Type—The SE and LVD devices can be connected to the same  
SCSI bus, however on power up, if at least one SE device is detected,  
the LVD devices must convert to SE mode, and SE mode will be used.  
Only the LVD interface is being specified for the Fast/40 and higher  
rates.  
• Device ID—Each device on a SCSI bus must have a unique ID. Also  
check the configured ID’s for the TC2201 to verify these are not in use  
by other devices on the same SCSI bus.  
• Cabling—Check SCSI cables to verify they are functional. SCSI rules  
for total length, distance between devices, and stub length must be  
adhered to. Connections should also be checked and reseated if  
necessary.  
Quantum TC2201 User’s Guide

Chapter 3 Troubleshooting  
Basic Verification  
• SCSI Devices—Verify that the SCSI devices on a particular SCSI Bus  
can be seen in the by the TC2201. Check the Discovery page to verify  
visibility of devices. If the TC2201 can not see the devices, verify SCSI  
configuration, cabling, and termination.  
Even if the SCSI devices are displayed, they are not accessible unless the  
mapping mode is auto-assigned or another non-empty map is used.  
Verify iSCSI Connection  
3 If SCSI devices are recognized on the SCSI buses, but do not appear to the  
iSCSI host, it may be that the iSCSI link is not properly established. Most  
switches have link indicators, showing link status. When the TC2201 is  
connected and powered-on, this link  
indicator should show a good link. If it does not, check the cabling or  
connections. As a means of verifying link integrity when connected to a  
functional host, disconnecting then reconnecting the Ethernet cable  
should cause momentary activity of this indicator as the link itself re  
initializes. Also verify that the media type of the TC2201 and attached  
switch are of corresponding types.  
Verify SCSI Devices in  
Windows NT  
Open the NT Control Panel, select “SCSI Adapters,” and double click on  
3 the iSCSI HBA. The SCSI devices should be listed.  
If no devices are listed, verify the TC2201 configuration, iSCSI HBA  
configuration, and cabling.  
If devices are listed, verify iSCSI HBA mapping mode and device  
addresses on the TC2201.  
Verify Configuration  
3 A number of configuration changes may result in an invalid  
configuration. If you are in doubt about the configuration, restore the  
TC2201 to the factory default configuration and proceed to configure the  
unit a step at a time, verifying the functionality of the configuration as  
changes are made.  
Verify Mapping  
3 Verify that all desired devices have been discovered and mapped. If  
using Indexed mapping, try swapping to Auto-assigned to see if this  
solves the problem.

Verify Devices  
3 It may be useful to connect the SCSI target devices you are attempting to  
use to the native SCSI interface to verify that the devices are functional.  
SCSI target devices can be connected to a host SCSI bus to verify they are  
functional.  
Verify Host Configuration 3 In some cases, it may be that the iSCSI host bus adapter or host device  
driver may not be working properly. Check the configuration of these  
elements. It may be useful to check the release notes for the driver  
provided to see if there are any specific issues or required configuration.  
It may also be useful to ensure that you are using a current version of the  
host bus adapter driver.  
Verify HBA Device Driver  
Information  
Check the HBA device driver Readme.txt file for configuration specifics.

BInband SCSI-3  
Commands  
The TC2201 supports a set of SCSI-3 commands that can be  
received inband over iSCSI. When received by the TC2201, these  
commands are then executed by the TC2201 itself.  
When using SCSI-3 commands to access general management  
features, the commands can be sent to device LUNs that are  
mapped through the TC2201.  
The following is a list of the SCSI-3 commands that are supported  
by the TC2201. Complete definitions of SCSI-3 commands can be  
found in the SCSI-3 standard available from the American  
National Standards Institute (ANSI).

When you press the TC2201’s power switch to the ‘ON’ position (marked  
with a ‘I’ symbol), a series of messages similar to the following appear on  
the terminal or terminal emulation program for the serial port (See “Serial  
Port Settings on page 14), or the Telnet utility for Telnet sessions.  
A series of power-up self tests are performed while the TC2201 starts  
(which can take up to 2 minutes), and messages related to these tests will  
be visible from the serial port. If completed successfully, the main menu  
will appear, as shown in Figure 7-1.  
Note: The illustrations in this chapter use Xs to represent numeric  
values for certain data fields, such as the product release  
version and the revision of firmware.  
Note: For the serial port, if you do not see messages over the  
Command Line Interface, you may need to re-check your  
computer’s serial port settings.

support for Dynamic Configuration Protocol. When enabled, the  
TC2201 will retrieve a dynamic IP address from a DHCP server  
located on the Ethernet network that the TC2201 is connected to.  
Once DHCP is enabled, it is necessary to save the current  
configuration and reboot the TC2201 before an IP address will be  
requested from the DHCP server. Use the following four steps:

After the TC2201 finishes rebooting, the Main Menu will appear on the  
serial port but, for Telnet, a new session will need to be opened to  
continue configuring the TC2201. DHCP status can be verified from the  
Ethernet Configuration Menu where DHCP Configuration is indicated as  
“Enabled” if DHCP has been successfully activated. Note that the IP  
address may also appear different than the former non-DHCP IP address.  
Note: To use the DHCP feature, a DHCP server must be operational on the  
Ethernet network used by the TC2201. If the DHCP feature is used  
when there is no DHCP server, the standard for DHCP requires that  
the TC2201 wait three minutes for a response from a DHCP server  
before timing out.  
Your DHCP server may allow you to set up a lease reservation for an IP  
address by providing the server with the Ethernet MAC address of the  
TC2201. This sets the DHCP server to always provide the same IP address  
to the TC2201. This setup can be useful for remote management of the  
TC2201 via Telnet or Visual Manager. Because the method of setting up a  
lease reservation varies depending on the DHCP server being used, it is  
recommended you contact your Network Administrator for assistance.  
For more information about configuring DHCP, see Appendix D of this  
manual.

discover SCSI devices. This value should be set to no less than 250ms,  
according to the SCSI standard for Reset-to-Selection Time. Quantum  
recommends you set the value to at least 2 seconds to ensure all SCSI  
devices complete their individual power-ups. With Discovery

Select 1 to toggle Buffered Tape Writes to enabled or disabled. The  
default setting is enabled. Buffered Tape Writes is an option designed  
to enhance system performance. By returning status on consecutive  
write commands prior to the tape device receiving data, Buffered  
Tape Writes remove the latency of waiting for responses from the  
tape device. In the event that data does not transfer correctly for any  
reason, the router will return a check condition on a subsequent  
command.  
Commands other than Write(6) are not issued until status is received  
for any pending write. Also, status is not returned until the device  
completes the command. For instance, when a synchronizing  
command is sent to a drive, such as sending a Write File mark, a good  
status means all prior commands have been successfully completed  
and data has been successfully written to the medium. This is  
appropriate for such tasks as file backup/restore.  
Note: If an application requires confirmation of individual blocks  
being written to the medium, such as audit trail tapes or log  
tapes, Buffered Tape Writes should be disabled.  
•
Select 2 to set Maximum Writes Outstanding. This setting determines  
the maximum number of writes that can be buffered. Any additional  
writes beyond the maximum level allowed will be sent to the storage  
device without using buffering, but these writes may also be  
subsequently buffered when completion notices for earlier writes are  
received.  
•
Select 3 to set Maximum Bytes Outstanding. This setting determines  
the maximum number of write bytes (shown in units of kilobytes)  
that can be buffered. Any additional writes beyond the maximum  
level allowed will be sent to the storage device without using  
buffering, but these writes may also be subsequently buffered when  
completion notices for earlier writes are received.

Device Mapping 3  
This option allows the user to manipulate maps and associate selected  
host with a particular map. Each physical port/bus on the system has at  
least an Indexed map and Auto Assigned map. Each map has a unique  
name and map ID. User may rename all maps, except for ‘Indexed’ and  
‘Auto Assigned’. The map that is set to be current must always contain  
valid information, since many of the operations on the map menu are

An IQN can be used by any organization that owns a domain name.  
According to IETF RFC 3720, an iSCSI qualified name string consists of:  
•
The string "iqn.", used to distinguish these names from "eui."  
formatted names.  
•
A date code, in yyyy-mm format. This date MUST be a date during  
which the naming authority owned the domain name used in this  
format, and SHOULD be the first month in which the domain name  
was owned by this naming authority at 00:01 GMT of the first day of  
the month. This date code uses the Gregorian calendar. All four digits  
in the year must be present. Both digits of the month must be present,  
with January == "01" and December == "12". The dash must be  
included.  
•
•
A dot "."  
The reversed domain name of the naming authority (person or  
organization) creating this iSCSI name. For example, if the domain  
name were “example.com”, then the reverse domain name would be  
“com.example”.

An optional, colon (:) prefixed, string within the character set and  
length boundaries that the owner of the domain name deems  
appropriate. This may contain product types, serial numbers, host  
identifiers, or software keys (e.g., it may include colons to separate  
organization boundaries). With the exception of the colon prefix, the  
owner of the domain name can assign everything after the reversed  
domain name as desired. It is the responsibility of the entity that is  
the naming authority to ensure that the iSCSI names it assigns are  
worldwide unique. For example, "Example Storage Arrays, Inc.",  
might own the domain name "example.com".

Select S from the Device Mapping menu to activate port mapping  
changes.  
Caution: Before activating any port mapping changes, it is strongly  
recommended that the user verify there are not any  
command or data operations occurring in conjunction  
with devices affected by the mapping changes. For  
example, deleting a LUN or device from a map may  
disrupt I/O transfers with that device. It is the user’s  
responsibility to ensure that no operations will be  
negatively impacted due to the activation of mapping  
changes.  
Note: All current Mapping Settings will take effect immediately! If  
another management interface has made unsaved mapping  
changes, those changes will be lost.  
Note: If the Activate Port Mapping Changes option is not selected,  
the mapping changes will not take effect unless the TC2201 is  
rebooted.  
Note: After the TC2201 reboots, the Configuration Menu will  
appear.

reboots the TC2201. Upon reboot, the TC2201 detects that there is a  
newly downloaded firmware image and copies that image to the boot  
sector of the FLASH and then boots with that image. At that point the  
TC2201 is using the new firmware.

Appendix D  
DUsing the FTP Interface  
This chapter describes specific management options available  
from the FTP interface.  
Backup/Restore Configuration Settings  
4
The TC2201 supports backup and restore of configuration  
settings over FTP. This allows users to maintain multiple setting  
configurations externally from the TC2201 and to be able to  
restore any of the configurations as needed. When backing up,  
configurations are saved from flash to a binary file.  
Configuration  
To backup the configuration file:  
Backup Procedure 4  
1 Connect the TC2201 to the ethernet network used by your  
computer.  
2 Start your FTP program using the TC2201’s IP address:  
ftp <IP address>  
Quantum TC2201 User’s Guide  
123  
Download from Www.Somanuals.com. All Manuals Search And Download.  
       
Backup/Restore Configuration Settings  
The default IP address is 1.1.1.1.  
Note: If the TC2201 is to use a static IP address, the default IP  
address 1.1.1.1 should be changed to an address that is  
appropriate for the IP network it will reside on. Note that the  
default IP address can be used in a direct connection between  
the TC2201 and the host computer via a crossover Ethernet  
cable.  
Note: You may also need to specify the directory location on your  
computer or network where your FTP program will store the  
backup file.  
3 Enter the user name and password. The default values for user name  
and password are root for the user name and password for the  
password.  
4 Specify binary mode:  
bin  
5 Specify the filename (.cfg file) with the get command:  
get filename.cfg  
(where “filename.cfg” can be any name for the configuration file.)  
The file will transfer to the current directory specified on your computer’s  
FTP utility. If running FTP from a DOS or Linux command line, the  
destination directory can be set using the lcd command (ex. lcd  
c:\myCfg).  
Note: World Wide Name (WWN) values and Ethernet physical  
address (MAC address) values will not be saved. Because user  
defined values for these settings are not retained in the  
configuration backup file, they must be re-entered after the  
configuration is restored. See the Configuration Restore  
Procedure later in this chapter for more information.  
Configuration Restore  
Procedure  
To restore a configuration file:  
4
1 Connect the TC2201 to the ethernet network used by your computer.  
2 Start your FTP program using the TC2201’s IP address:  
Quantum TC2201 User’s Guide  
124

Backup/Restore Configuration Settings  
ftp <IP address>  
The default IP address is 1.1.1.1.  
Note: If the TC2201 is to use a static IP address, the default IP  
address 1.1.1.1 should be changed to an address that is  
appropriate for the IP network it will reside on. Note that the  
default IP address can be used in a direct connection between  
the TC2201 and the host computer via a crossover Ethernet  
cable.  
3 Enter the user name and password. The default values for user name  
and password are root for the user name and password for the  
password.  
4 Specify binary mode:  
bin  
5 Specify the configuration’s path and filename (.cfg file) with the put  
command:  
put <path:filename.cfg>  
The file will transfer and the TC2201 will reboot. The TC2201 will then be  
using the configuration.  
Note: World Wide Name (WWN) values and Ethernet physical

The default IP address is 1.1.1.1.  
Note: You may also need to specify the directory location on your  
computer or network where your FTP program will store the  
trace file.  
Note: If the TC2201 is to use a static IP address, the default IP  
address 1.1.1.1 should be changed to an address that is  
appropriate for the IP network it will reside on. Note that the  
default IP address can be used in a direct connection between  
the TC2201 and the host computer via a crossover Ethernet  
cable.  
3 Enter the user name and password. The default values for user name  
and password are root for the user name and password for the  
password.

Procedure F: HP Data Protector  
1
In order to increase the maximum block size on a Windows Media Agent  
client, you must first modify its Registry. After modifying the Registry,  
restart the computer. Drivers read MaximumSGList at boot time. The  
actual formula that a Windows class driver uses to determine the  
maximum transfer size is:  
maximum size = ((number of supported scatter/gather elements - 1)*  
4096)  
For the typical aic78xx case, it renders the following:  
((17-1) * 4096) = 64k (which corresponds to 56k usable data for Data  
Protector)  
Windows provides a mechanism to support more scatter/gather  
elements via the Registry.  
6 Start the regedit32 and add a DWORD value in the following  
Registry key:  
\\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic  
es\aic78 xx\Parameters\Device0\MaximumSGList  
Quantum TC2201 User’s Guide  
133  
Download from Www.Somanuals.com. All Manuals Search And Download.  
   
Procedure F: HP Data Protector  
7 Use the following formula to calculate the value of the  
MaximumSGList:  
MaximumSGList = (BlockSize/4096)+1  
For example, the MaximumSGList value for a 256k block size is 65, as  
follows:  
MaximumSGList = (265k/4k) + 1 = 64 + 1 = 65  
If you have, for example, three aic78xx based SCSI channels on your  
system, change the appropriate ...\Device0, ...\Device1 or ...\Device2  
value. If you want to set all adapters at the same time, specify  
MaximumSGList for ...\Device\.... Omitting the numerical reference  
sets the value for all aic78xx adapters.  
The block size can also be changed using the Data Protector management  
interface.  
1 To do this, select the Devices & Media option from the drop down  
list.  
2 Right click on a discovered tape device and select Properties.  
3 Select the Settings tab and then click on the Advanced button.  
4 Select the Sizes tab and from here the block size can be modified as  
shown in figure 51 below.

Differential An electrical signal configuration using a pair of lines for  
data transfer. The advantage of differential compared to single-ended  
configuration is a relative high tolerance for common-mode noise and  
crosstalk when used with twisted pair cables. In layman’s terms, this  
means longer distance.  
E
Ethernet MTU Maximum Transmission Unit, the largest physical packet  
size, measured in bytes, that a network can transmit. Any messages larger  
than the MTU are divided into smaller packets before being sent.  
Exchange A iSCSI term for the basic mechanism used for managing an  
operation. An exchange identifies information transfers consisting of one  
or more related nonconcurrent sequences that may flow in the same or  
opposite directions, but always in half duplex mode. An exchange is  
identified by an OX_ID and an RX_ID.  
F
Fabric An iSCSI term that includes iSCSI Arbitrated Loop, Switched  
Fabric, and Point-to-Point.  
Fault LED During power up and self test, the TC2201 Fault LED comes  
on. After self test, if this LED remains on or comes on, the TC2201 has a  
problem with one of its components. During normal operation, this LED  
should be off.  
Fiber A fiber optic cable made from thin strands of glass through which  
data in the form of light pulses is transmitted (LASER, LED). It is often  
used for high-speed transmission over medium (200m) to long (10km)  
distances but it can be used for short distances (<200m).

performed by another device known as a target (usually a peripheral).  
Initiator Mode Configuration mode of the TC2201 in which a Fibre  
Channel initiator requests operations to be performed by a SCSI target  
device.  
IP Internet protocol  
iSCSI (Internet SCSI) iSCSI is Internet SCSI (Small Computer System  
Interface), an Internet Protocol (IP)-based storage networking standard  
for linking data storage resources, developed by the Internet Engineering  
Task Force (IETF). By carrying SCSI commands over IP networks, iSCSI is  
used to facilitate data transfers.  
iSCSI Portal Groups A Portal Group defines a set of Network Portals  
within an iSCSI Network Entity that collectively supports the capability  
of coordinating a session with connections spanning these portals. Not all  
Network Portals within a Portal Group need participate in every session  
connected through that Portal Group. One or more Portal Groups may  
provide access to an iSCSI Node. Each Network Portal, as utilized by a  
given iSCSI Node, belongs to exactly one portal group within that node.  
iSNS iSNS allows the administrator to go beyond a simple device-by-  
device management model, where each storage device is manually and  
individually configured with its own list of known initiators and targets.  
Using iSNS, each storage device subordinates its discovery and  
management responsibilities to the iSNS server. The iSNS server thereby  
serves as the consolidated configuration point through which  
management stations can configure and manage the entire storage  
network.

Target A device (usually a peripheral) that responds to an operation  
requested by an initiator (usually a host system). Peripherals are targets,  
but for some commands (for example, a SCSI COPY command), the  
peripheral may need to act temporarily as an initiator.  
Terminator Block/Termination An electrical connection at each end of the  
SCSI bus composed of a set of resistors (or possibly other components).  
Its function is to provide a pull-up for open collector drivers on the bus,  
and also impedance matching to prevent signal reflections at the ends of  
the cable.  
The SCSI bus requires termination at both ends of the bus. One end of the  
SCSI bus is terminated by the SCSI adapter’s internal termination. The  
other end should have a terminator placed on the SCSI connector on the  
last SCSI peripheral. If this device is not terminated, data errors may  
occur.
