Operation Indicators
The air intake vents shown in figure 1 provide cooling for the unit during
operation and should always remain unobstructed. The exhaust vent for
air is located on the back panel.

Besides the air-exhaust vents, SCSI and iSCSI interfaces are found on the
back panel. Also on the back panel, Ethernet and Serial ports provide
connections for configuration and management of the unit. The LEDs
(operation indicators) provide basic status information. In addition, a
power connector and power switch are located on the back panel along
with a Reset Button that is used to manually force a reboot of the
TC2201E. For proper operation of the TC2201E, cable connections on the
back panel should remain securely in place.

The TC2201E is equipped with rear panel LED indicators for monitoring
overall unit status (see figure 3).

The LED functionality of the TC2201E is detailed below:
•
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 TC2201E detects a fault condition in the TC2201E.
•
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 TC2201E Works
1
The TC2201E 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
Figure 4 shows a host accessing SCSI tape drives and libraries via the
TC2201E.

Processing SCSI Information
1
The following section describes how the TC2201E processes SCSI
information when attached to iSCSI hosts. Figure 5 illustrates steps 1
through 5 of the process.
1 A iSCSI host issues a command. The iSCSI host encapsulates the
command in the iSCSI protocol and sends the packet to the TC2201E.
2 The iSCSI controller in the TC2201E receives the packet, interprets the
iSCSI information, and places the packet in buffer memory.
3 The TC2201E’s processor interprets the information and programs a
SCSI controller to process the transaction.
4 The SCSI controller sends the command to the SCSI device (target).
5 The SCSI target interprets the command and executes it.

up to 400 MB/s bi-directional for both ports (or 200 MB/s each way for
both ports together). The TC2201E performs fast tape reads and writes,
which enables it to handle larger data sets while completing backup and
restore tasks within a smaller timeframe.
Ease of Use to Reduce
SAN Management
The Quantum TC2201E is significantly easier to install than other routers
Costs and
due to the “store-and-forward” configuration feature and the Visual
Complexity
1Manager (VM) software. “Store-and-forward” allows configuration files
and TC2201E 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 TC2201E with simple “point and click”
choices on a graphical representation of the TC2201E.
Add Intelligence to
SCSI Storage

The TC2201E has many features that provide intelligence to SCSI devices
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 TC2201E
provide customers with a high level of storage functionality for high
performance backup and recovery, reliability, security and manageability
in their nearline storage solutions.

Before connecting the TC2201E to other iSCSI devices, it is important to
understand the configuration requirements of the environment to which
it will be connected. Failure to correctly configure an iSCSI device may
impair the operation of the network to which it is attached.
The iSCSI RJ-45 connectors on the unit can be directly connected to a
standard 10/100/1000BaseT Ethernet network.
Typical installations will have the TC2201E connected to an Ethernet
switch.
Ethernet switches may allow for individual ports to be configured for
different media types. The TC2201E must be connected to the switch port
with the appropriate Ethernet cabling for both the TC2201E and the

10/100BaseT Ethernet connectivity provides enhanced management and
configuration capabilities. The RJ-45 connector on the unit can be directly
connected to a standard 10/100BaseT Ethernet network.
If your network does not have a DHCP server, you will need to manually
configure an IP address via the serial port using the Command Line
Interface (see appendix C, Using the Command Line Interface).
For more information about the IP network address and the visual
management system, refer to the chapter 3, Quantum Visual Manager.
Note:
For manual configuration of the IP address, the TC2201E’s
default IP address is 1.1.1.1 but this is technically not a valid IP
address. It is recommended that you change the setting to a
valid address, as described in appendix C.

6 Proceed to the following instructions on connecting the power to the
TC2201E.
Connecting the
Power Cable
2
The power supply used with the TC2201E supports 100 - 240 VAC (Auto
Sensing), but the correct type of power cable needed for your installation
should still be verified. The power cable shipped with the TC2201E is a
120 VAC 3-conductor power cable for use in the United States and
Canada. This is the power cable that should be used with the TC2201E
unless your installation requires otherwise, in which case you should
obtain the appropriate power cable as needed.
To connect the power cable to the TC2201E:
1 Connect the female end of the power cable to the power connector on
the back panel of the TC2201E.
2 Plug the male end of the power cable into the power source.
3 Switch on power to the TC2201E using the Power Switch located on
the back panel of the TC2201E.
If accessing the serial port, once you set the baud rate in the terminal
emulator, wait until the TC2201E completes the Power-On Self Test
(POST) and then the Firmware Initialization process. This can take up
24
Quantum TC2201E User’s Guide
Chapter 2 Getting Started
Configuring the TC2201E
to 90 seconds, during which time the POST and initialization
information may or may not be visible on the terminal or terminal
emulator.
The baud rate used by the terminal or terminal emulator must be
9600, 19200, 38400, 57600, or 115200. The TC2201E will not function
properly at any other baud rate.
Once the POST and firmware initiation processes are complete, the

Chapter 2 Getting Started
Configuring the TC2201E
configured for network operation of the TC2201E. Depending on the
network environment, it may be possible to use the TC2201E’s
default IP address of 1.1.1.1 to configure the unit.
Note:
In the event that DHCP is not used, note that the
TC2201E’s default IP address of 1.1.1.1 is technically not a
valid IP address. It is recommended that you should
change the setting to an IP address that is a valid address
(via the serial port using the Command Line Interface).
Refer to Using the Command Line Interface on page 103
for information on configuring the IP address.
2 Verify that the Ethernet and iSCSI ports all have good network
connections. This can be accomplished by issuing a standard “ping”
command to the IP addresses for each port. In the event that a port
fails to respond, check all cable connections (use new cables where
necessary) and be sure there is a good link light showing on the
network switch for all connections to the TC2201E.
3 To begin configuration of the TC2201E, enter the IP address of the
Ethernet management port into the web browser address field and
press the Enter key. The home page of the TC2201E should appear. If
not, please verify the IP address or use the Command Line Interface
instructions in the next section.
4 In the Home page of the Visual Manager interface, select “Ethernet”
from the Main menu on the left.
5 When the security prompt appears, enter the appropriate user name
and password values and then select the Submit button. The default
user name is ‘root’ and the default password is ‘password’.
6 The Ethernet page will appear. Select each Ethernet port from the
menu on the left and verify that all Ethernet settings are correct for
the network environment that the TC2201E is connected to.
7 Select the Discovery page to verify that all target devices are visible as
expected and that the status for each device appears as expected (i.e.
in the “UP” state). If any device is shown in the “DOWN” state,
inspect that device. If a device fails to appear at all, make sure the
26

device is powered on and check cable connections. It may be
necessary to perform a manual discovery (select GO button) or to
reboot the TC2201E (menu selection on left).
Note:
During reboot, some older browsers will need to be
manually returned to the desired page after the reboot
page counter has completed counting down to "0".
8 Select the SCSI Bus page. SCSI ID 7 is the default SCSI Initiator ID for
each of the TC2201E’s SCSI buses. If any devices attached to a
TC2201E bus are using SCSI ID 7, then that bus's Initiator ID must be
changed. To change a bus's Initiator ID: Select the desired bus from
the TC2201E GUI or the SCSI Bus submenu. Then use the Initiator ID
field drop-down list to select an unused ID number. Click the Submit
button to record the change.
If the TC2201E does not see all of the devices expected, check that the
initiator ID(s) are set to a unique value for each bus attached to
devices. For any changes, submit those changes and reboot the
TC2201E.
You have now successfully configured the TC2201E. This procedure
may not apply to all situations but does address most key issues
required for initial setup.
Configuring the
TC2201D Using
the Command Line

To configure the TC2201E from the command line interface:
1 Establish communications over the serial port and then bring up the
Command Line Interface (CLI).
2 In the main menu of the CLI, several menu options should be visible.
Select menu option 1, “Perform Configuration” and then menu
option 3, “Ethernet”.
3 To enable remote management capabilities, toggle DHCP to Enabled
or enter a valid IP address and IP gateway, so that the TC2201E is
configured properly for network operation. When Ethernet settings
are complete, select X to go back to the main configuration menu.
4 Select menu option 5 to access the SCSI Bus menu. SCSI ID 7 is the
default SCSI Initiator ID for each of the TC2201E’s SCSI buses. If any
devices attached to a TC2201E bus are using SCSI ID 7, then that bus's
Initiator ID must be changed. To change a bus's Initiator ID: Select

connections. It may be necessary to perform a manual discovery
(select menu option 1, 2, or 3) or to reboot the TC2201E (from main
menu). Select X four times to return to the Configuration menu.
11 Select menu option 4 to reboot the TC2201E. In about 2 minutes, the
TC2201E will once again display the main menu.
12 If the TC2201E does not see all of the devices expected, repeat step 3
above, and check that the initiator ID(s) are set to a unique value for
the selected bus. Again, you must save any changes and reboot the
TC2201E.
You have now successfully configured the TC2201E. This procedure
may not apply to all situations, but does address most key issues
required for initial setup.
Save Backup Version of Configuration
2
Once all desired configuration settings are in place, it is recommended to
save a backup version of the configuration settings. By doing so, this will
help ensure that in the event of a serious problem such as a forgotten user
name or password, it will be possible to restore all the settings. For more
information, see Using the FTP Interface on page 155.

configuration settings that can be used to enhance operation and security.
For more information about the settings described in this section, see
Chapters 6 and 7 of this manual.

Secure Connections
CHAP (Challenge-Handshake Authentication Protocol) provides a secure
procedure for connecting to systems, as follows:
1 After a link is made, the TC2201E sends a challenge message to the
connection requestor. The requestor responds with a value obtained
by using a one-way hash function.
2 The TC2201E checks the response by comparing it its own calculation
of the expected hash value.
3 If the values match, the authentication is acknowledged; otherwise
the connection is usually terminated.
At any time, the TC2201E can request the connected party to send a
new challenge message. CHAP identifiers are changed frequently
and authentication can be requested by the TC2201E at any time.
Port Failover
2
The iSCSI Portal Group Settings primarily serve to provide port failover
functionality for the TC2201E. By default, the TC2201E is set to use one
Portal Group for both ports, which effectively enables failover capability
between the two iSCSI ports.However, this option can be disabled so that
each port can be mapped separately.

Automated Device Discovery
2
iSNS servers maintain information about iSCSI clients and will respond
to iSNS protocol queries and requests, and initiate iSNS protocol State
Change Notifications. To use iSNS with the TC2201E, simply enable the
TC2201E as a client and then enter a DNS name or IP address for up to
three iSNS servers.
The default setting is Disabled. When enabled, the TC2201E will function
as an iSNS client and will initiate transactions with iSNS servers using the
iSNSP. The iSNS client is a process that is co-resident in the TC2201E, and
which can register device attribute information with the iSNS server. The
capability is used for automated device discovery.
SCSI
Configuration
2
For SCSI devices, the TC2201E provides a number of optional
configuration settings that can be used to enhance operation and security.
Buffered Tape Writes
2
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:
30
By default, the Buffered Tape Writes option is disabled. If the
application requires confirmation of individual blocks being
written to the medium, such as audit trail tapes or log tapes,
this option should be disabled.

1 Connect a 10baseT or 100baseT Ethernet cable to the TC2201E.
2 Apply power to any connected SCSI or iSCSI devices.
3 After all attached devices have gone through their power up routines,
boot up the TC2201E.
4 Turn on the host computer.
5 If the IP address for the TC2201E is known, open the computer’s Web
browser and enter the IP address into the Address field. The factory
default of the TC2201E has DHCP enabled. To disable DHCP, refer to
appendix C, Using the Command Line Interface for information on
disabling the DHCP option.
Note:
For manual IP address configuration, the TC2201E has a
default fixed IP address of 1.1.1.1 but this is technically not a
valid IP address. For remote access from WAN or Internet
locations, the IP address must be changed to a valid IP
address. Valid IP addresses have the form x.x.x.x where each x
is an integer in the range of 0 to 255.
If you do not know the IP address of the TC2201E, then connect to the
TC2201E using the serial (RS-232) connection (a 3-pin serial cable is
included with the TC2201E). Current settings can be viewed and
changed from the Ethernet Configuration Menu of the serial
interface.
32
Note:
To access the QVM user interface, the TC2201E must be
assigned an IP address.
Note:
If the TC2201E 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 TC2201E and the host computer via a crossover Ethernet
cable.

6 Once the host computer's web browser can access the TC2201E,
Quantum Visual Manager (QVM) will display the TC2201E's "Home
page" in the browser window. This page provides a high-level
snapshot of the TC2201E's status, and is accessible to anyone who
knows (and can reach) the TC2201E's IP address. The Report Page is
also accessible without needing special access. However, additional
TC2201E information, and all TC2201E configuration settings, are
user- and password-protected. Selecting other options will cause a
login window to appear, where the user can enter a user name and
password. The TC2201E defaults are root for user name and password
for password. This information is required only once per session
(described below).
Note:
For the QVM interface’s dynamic display of the TC2201E
configuration to be presented properly, use version 6.2 or later
of Netscape’s browser on non-Solaris platforms, or Netscape
version 6.2.3 for Solaris platforms. If using Internet Explorer,
use revision 6.0 or later.
Note:
It is recommended to change the user name and password
from the defaults. For more information, see Main Menu >
System > User Settings.
7 Upon successful login, the user has initiated a "session", and has full
access to the TC2201E QVM for the duration of the session. A session
ends when the user exits all instances of the web browser. Log-in will
be required again, via the TC2201E's home page, to initiate a new
session.
Note:
To end the current session of Visual Manager, it is necessary to
close all instances of the browser window. Merely navigating
the browser to another URL is not sufficient to end the current
session.

Note:
It is recommended not to bookmark Visual Manager pages with a
Web browser. Because configuration information is transmitted via
URLs, the use of bookmarks could cause the TC2201E to be
configured with information present when the bookmark was
created. For similar reasons, it is also recommended not to use
navigation features of the Web browser (such as the Back or Refresh/
Reload buttons) to navigate Visual Manager.
It is recommended that you navigate only using the Web page links
contained in Visual Manager itself. Depending on the Web browser used,
these links will often appear as highlighted text. By clicking on these
links, Visual Manager can be safely navigated.

Protocol (DHCP). When enabled, the TC2201E will retrieve a
dynamic IP address from a DHCP server located on the Ethernet
network that the TC2201E is connected to. The default setting is
Enabled. If DHCP is changed from Disabled to Enabled, it is
necessary to reboot the TC2201E before an IP address will be
requested from the DHCP server. After the TC2201E finishes
rebooting, the QVM session will have to be restarted. The TC2201E'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 TC2201E. If the
DHCP feature is used when there is no DHCP server, the
standard for DHCP requires that the TC2201E wait three
minutes for a response from a DHCP server before timing out.
During this period, the TC2201E 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 TC2201E. This
forces the DHCP server to always provide the same IP address to the
TC2201E. This setup is useful for remote management of the TC2201E
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.

Troubleshooting

Various problems can arise when configuring and using the TC2201E.
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 TC2201E is equipped with rear panel LED indicators for monitoring
overall unit status.

The LED functionality of the TC2201E 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 TC2201E
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

Serial Port
Problems

Verify SCSI Bus
Configuration

4
If you experience trouble communicating with the serial port, verify the
configuration of the host terminal or terminal emulation program. The
TC2201E 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.
Problems with SCSI bus configuration are common. Basic operation of a
SCSI bus can be checked by using the configuration menu to view
attached SCSI devices. See “Chapter 7 for more
information. Other 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 TC2201E to verify these are not in
use by other devices on the same SCSI bus.
Quantum TC2201E User’s Guide
89
Chapter 4 Troubleshooting
Basic Verification
•
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.
•
SCSI Devices—Verify that the SCSI devices on a particular SCSI Bus
can be seen in the by the TC2201E. Check the Discovery page to
verify visibility of devices. If the TC2201E 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.
If SCSI devices are recognized on the SCSI buses, but do not appear to the
Verify iSCSI
Connection
4 iSCSI host, it may be that the iSCSI link is not properly established. Most
switches have link indicators, showing link status. When the TC2201E 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 TC2201E and attached
switch are of corresponding types.

Select 1 to toggle the DHCP setting. This setting enables/disables
support for Dynamic Configuration Protocol. When enabled, the
TC2201E will retrieve a dynamic IP address from a DHCP server
located on the Ethernet network that the TC2201E is connected to.
Once DHCP is enabled, it is necessary to save the current
configuration and reboot the TC2201E before an IP address will be
requested from the DHCP server. Use the following four steps:
Quantum TC2201E User’s Guide

Perform Configuration
1 Select X Return to previous menu
2 Select A Save Configuration
3 Select X Return to previous menu
4 Select 4 Reboot
After the TC2201E 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 TC2201E. 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 TC2201E. If the DHCP feature is used
when there is no DHCP server, the standard for DHCP requires that
the TC2201E 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
TC2201E. This sets the DHCP server to always provide the same IP
address to the TC2201E. This setup can be useful for remote management
of the TC2201E 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.

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.

For the iSCSI initiator name, use an iSCSI-Qualified Name (IQN) for the
host being added. This information is available from the iSCSI Initiator.
For additional details, see the user documentation included with the
iSCSI Initiator software.
Note:
The Quantum TC2201E does not include iSCSI Initiator
software. For additional details, contact the operating system
provider.
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".
An example of an iSCSI-qualified name string is as follows:

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 TC2201E is
rebooted.
Note:
After the TC2201E reboots, the Configuration Menu will
appear.
This option allows set up of trace and events settings.

Procedure F: HP Data Protector
5
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.
Quantum TC2201E User’s Guide
167
Procedure F: HP Data Protector
6 Start the regedit32 and add a DWORD value in the following
Registry key:
\\HKEY_LOCAL_
MACHINE\SYSTEM\CurrentControlSet\Services\aic78
xx\Parameters\Device0\MaximumSGList
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

13, 12, 11, 10, 9, 8, with “8” being the lowest priority address.
The narrow SCSI adapter is factory set to address 7. A narrow
SCSI adapter supports up to eight devices, including itself. SCSI
address “7” has the highest priority followed by 6, 5, 4, 3, 2, 1,
and 0.
SCSI bus
The means of transferring SCSI data between SCSI devices. It is
an 8-bit or 16-bit bus that supports up to eight or sixteen devices
(including itself), in any mix of initiators and targets, with the
limitation that at least one initiator and one target must be
present.
SCSI device
A single unit on the SCSI bus, identifiable by a unique SCSI
address. A SCSI device can act as an initiator or target. For
SCSI-3, each SCSI device supports up to sixteen LUNs.
SCSI port
An opening at the back of the TC2201E providing connection
between the SCSI adapter and the SCSI bus.
SCSI status
A menu name used to show the number of SCSI devices on the
bus.
synch and steering layer
A function of iSCSI Fixed Interval Markers (FIMs) used for
synchronization and steering of iSCSI Protocol Data Units
(PDUs) especially in regards to high-speed iSCSI
implementations.

Glossary
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.
topology
The physical or logical layout of nodes on a network. FC
topologies include Point-to-Point, FC-AL, and Fabric.
trap
In the context of SNMP, an unsolicited message sent by an agent
to a management station. The purpose is to notify the
management station of some unusual event.
V
view node name
A status type in the FC Status Menu showing the identification
of the node.
view port name
A status type in the FC Status Menu showing the identification
of the port.
