The iSCSI Target Configuration appears with the revised information.
Setting an ISID Value
The ISID qualifier is a unique ISID value to specify if you are connecting dual sessions
to the same target portal group. This value ensures that you do not log into the same
session twice. A combination of the initiator name, ISID qualifier, target name, and
target portal group defines an iSCSI session. For the ISID qualifier, you can enter a
number up to 65535.
To set the ISID Qualifier:
1. Log into the iSCSISelect utility by pressing <Ctrl+S> when prompted.
2. Select Controller Configuration and press <Enter>. A list of controllers is
displayed.
3. Select a controller and press <Enter>. The Controller Configuration menu is
displayed.
4. From the Controller Configuration menu, select iSCSI Target Configuration and
press <Enter>.
5. Select Add New iSCSI Target and press <Enter>.
6. From the Add/Ping iSCSI Target dialog box, select ISID Qualifier and type in a
numeric value.
7. To save your changes, select Save/Login and press <Enter>.
The iSCSI Target Configuration appears with the revised information.
For more information on when an ISID value must be changed, see “Booting from SAN
for iSCSI MPIO” on page 1574.
Enabling CHAP Authentication
The iSCSISelect utility uses CHAP to authenticate initiators and targets for added
network security. By using a challenge/response security mechanism, CHAP
periodically verifies the initiator's identity. This authentication method depends on a
secret known only to the initiator and the target. Although the authentication can be
one-way, you can negotiate CHAP in both directions with the help of the same secret
set for mutual authentication. You must make sure however, that what you configure
on the target side, matches the initiator side. The iSCSISelect utility supports both
one-way and mutual authentication.
Authenticating One-Way CHAP
With one-way CHAP authentication, the target authenticates the initiator. Use one-way
CHAP authentication for a one-way challenge/response security method.
To enable one-way CHAP authentication:
1. Log into the iSCSISelect utility by pressing <Ctrl+S> when prompted.
2. Select Controller Configuration. A list of controllers is displayed.
3. Select a controller and press <Enter>. The Controller Configuration menu is
displayed.
