Introduction 3
Introduction 0
The Quantum Scalar 50 automated tape libraries are controlled by a host
computer via a SCSI LVD bus using the SCSI-3 medium changer command
set.
The Quantum Scalar 50 allows for easy conversion from the SCSI host
interface to an iSCSI host interface. This document describes upgrading a
standard Scalar 50 library equipped with a SCSI host interface to an iSCSI
host interface using a TC2201 Upgrade kit.
TC2201 Bridge
Operation 0
Once a TC2201 bridge option is installed and tested, the library operates
exactly as a Scalar 50 with a SCSI host interface. Operation of the library via
the operator control panel (OCP) is unchanged.
Preparing for the TC2201 Installation 0
Before beginning the installation procedure, make sure that you have the
required upgrade kit and tools.
Required Upgrade Kits 0The TC2201 installation requires the following upgrade kit for every two tape
drives in a Scalar 50 library (see table 1):

Configuring the
TC2201 Bridge
Software 0
After the TC2201 is installed, you must configure the bridge and map the tape
drives and library robotics controller to the iSCSI port. Configuring the
TC2201 consists of the following steps:
•Accessing the TC2201 Bridge
•Discovering Attached Devices
•Configuring the iSCSI Ports
Accessing the TC2201 Bridge 0
To access the TC2201 bridge:
1Turn on the library power by pressing the power button located on the
front of the library (see figure 2).
2Open a web browser on a PC located on the same subnet as the library.
3In the Address field, type http://IPaddress/ where IP address is the IP
address for the Scalar 50 library (refer to the Quantum Scalar 50 User’s
Guide PN 81-81768 for information on the Scalar 50 remote management
web pages).
4Select the iSCSI Bridge tab from the Setup page on the Scalar 50 remote
management web pages.

SCSI ID 7 is the default SCSI Initiator ID for each of the TC2201’s SCSI
buses. If any devices attached to a TC2201 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 TC2201 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.

TC2201 Upgrade Procedure 15
If the TC2201 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 TC2201.
Configuring the iSCSI Ports 0
After you have discovered the attached devices, you must:
• Configure the iSCSI ports with an iSCSI host
and
• Map the tape drive and media changer to the iSCSI ports.
To configure the iSCSI ports:
1Click iSCSI Mapping from the Main menu.
The iSCSI Mapping screen displays (see figure 16).
Figure 16 iSCSI Mapping
Screen
2Select the iSCSI port to configure.
The current mapping information for that port is displayed including the
name of the port, the currently selected host and map.
3There are two ways to configure the iSCSI host:
aAdd a new host or map by clicking Add.
bSelect an existing host or map from the pull-down lists for Select Host
and Select Map.
If you are adding a new host or map and click Add, the iSCSI Host Add
screen displays (see figure 17).

After the iSCSI host information is configured, you must map the
attached devices to the appropriate iSCSI port.
7From the iSCSI Mapping screen, click Select Current Map Edit/View.
The Select Current Map Edit/View screen displays (see figure 18).
Note: Host settings are saved to memory when the Submit button is
selected but are not activated until either the Activate Mapping
Changes button is selected or the TC2201 is rebooted.

8To map the iSCSI ports:
aTo completely clear the current map of all entries, select the Clear Map
button.
bTo fill the map, select the fill option from the pull-down list and then
select the Fill Map button. When the map is filled, the menu shows the
current mappings.
cTo remove all gaps, or unfilled entries, from this map, select the
Remove Gaps button. When removing gaps from the table, this
option also renumbers all Indexes in sequential order starting with
Index 0.
dTo delete a specific map entry, select an Index from the pull-down list
under Delete Map Item. To delete multiple Indexes, also select the end
of the range from the optional pull-down list. Either way, select the
Delete Entry button to remove the item(s) from the map.
Note: The iqn name may be necessary for some customer iSCSI host
configurations.
Note: Some operating systems require gaps be removed in the
mapping table in order to detect all devices.

18 TC2201 Upgrade Procedure
eTo create a specific map item, the Index, Bus, and Device can be
selected from the pull-down lists for either Discovered Device Entry or
Manual Device Entry. Discovered Device Entry is limited to devices
already discovered. Manual Device Entry allows you to manually set
up a device type at a specific Device Target and Device LUN. To make
the changes permanent, select the Create Entry button.
9After the iSCSI ports are mapped, select the Activate Mapping Changes
button to dynamically update the current map without rebooting the
TC2201. These changes are made effective immediately after being
submitted.
10 After activating the mapping options for the Ethernet ports, click Reboot
from the Main menu.
The System Reboot screen displays (see figure 19).
Note: Maps named Auto Assigned may not be modified, cleared,
filled, or have entries removed.
Note: Map settings are saved to memory when any of the buttons
within the page are selected but are not activated until either
the Activate Mapping Changes button is selected or the TC2201
is rebooted.
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 Mapping Changes button is not selected, the
mapping changes will not take effect unless the TC2201 is
rebooted.
