How the TC2201E Works1
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 Information1
The following section describes how the TC2201E processes SCSI
information when attached to iSCSI hosts.
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.

The TC2201E offers enterprise class performance with memory buffer
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 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.
The Quantum TC2201E is significantly easier to install than other routers
due to the “store-and-forward” configuration feature and the Visual
Manager (VM) software. “Store-and-forward” allows configuration files
1
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.
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.

6 Proceed to the following instructions on connecting the power to the
TC2201E.
The power supply used with the TC2201E supports 100 - 240 VAC (Auto
Sensing), but the correct type of power cable needed for your installation
2
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

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

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 Configuration2
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

Advanced Configuration Options
Advanced Configuration Options2
The following two sections provide some advanced configuration tips
that go beyond the quick setup procedures listed above.
iSCSI
Configuration
For iSCSI environments, the TC2201E provides a number of optional
configuration settings that can be used to enhance operation and security.
2
For more information about the settings described in this section, see
Chapters 6 and 7 of this manual.
Secure Connections 2
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 Failover2
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.
Quantum TC2201E User’s Guide29
Chapter 2 Getting Started
Advanced Configuration Options
Automated Device Discovery2
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
For SCSI devices, the TC2201E provides a number of optional
configuration settings that can be used to enhance operation and security.
2
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: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.

3Quantum Visual Manager
This chapter describes the Quantum Visual Manager (QVM). The current
configuration and operating status of the TC2201E can be accessed from
any standard Web browser, after the user logs in with the appropriate
username and password. Information is presented in HTML format in
accordance with the W3C specification for HTML 3.2. Current W3C
Recommendations and other technical documents can be found at
/www.w3.org/TR.
Visual Manager allows access to configuration settings such as:
•Baud rate of the serial port
•iSCSI settings
http:/
•Ethernet address
•Device maps and host associations
•Trace level and event log settings
Most settings may be changed and saved to the TC2201E.
Note:Unless otherwise indicated, configuration changes take effect
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.
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.

Note:For DHCP usage information, see the Network settings in this
chapter and in Appendix D.
Note:Unless otherwise indicated, configuration changes take effect
when the unit next powers on or reboots.
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.

Making Changes via Visual Manager3
To make changes to settings, use a standard keyboard and mouse to enter
new information. Select the Submit button to send changes from the Web
browser to the TC2201E. Other than dynamic mapping changes,
configuration changes will not take effect until the next time the TC2201E
reboots. The unit can be forced to reboot by selecting the Reboot option
from the Main Menu.
Detailed instructions about all settings are provided later in this chapter.
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.

•DNS Server IP Address is the IP address for the DNS server and
should be similar in form to XXX.XXX.XXX.XXX where each XXX
represents an integer in the range of 1 to 255.
•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 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.

•Current MAC address is the current Media Access Control (MAC)
address configured for the TC2201E. 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
TC2201E 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

does negotiate to use Ultra SCSI-3 but somehow cannot actually
handle the speed. The default setting is Enabled.

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

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
