Changing the iSCSI Name
To edit the iSCSI initiator name:
1. On the iBFT Configuration screen, highlight iSCSI Name and press <Enter>.
This is a global setting. The iSCSI initiator name configured on one adapter is
reflected on all adapters in the system.
Note: HP systems are an exception to the previous statement. Each port on an HP
system can be configured with a unique initiator name.
Selecting Multipath I/O
MPIO support allows the initiator to log in dual sessions to the same target. In this way
I/O can be sent over either TCP/IP connection to the target. If one session fails another
session can continue processing I/O without interruption to the application. In iSCSI
target configuration, you have the option of setting dual network paths to a single boot
LUN.
Note: Although MPIO boot support allows the initiator to log into multiple sessions,
the iSCSI BIOS currently limits the number of sessions to two iSCSI sessions for
a single boot LUN.
You must follow these steps in this order to configure MPIO boot support for each
operating system.
1. Use the Emulex iSCSI configuration utility to configure the first path to a boot
target.
2. Complete normal operating system installation.
3. Install third-party MPIO software for your operating system.
4. Configure the second path to a single boot LUN through the Emulex iSCSI
configuration utility.
To select Multipath I/O:
1. On the iBFT Configuration screen, select Multipath IO and press <Enter>.
2. From the Multipath IO pop-up menu, select Enable or Disable and press <Enter>.
Configuring CHAP Authentication Mode
Emulex 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. Emulex supports both one-way and mutual authentication.
To configure the CHAP authentication method:
1. On the iBFT Configuration screen, select CHAP Authentication Mode and press
<Enter>.
