Creating CHAP secrets
When you set up an authentication method, you can choose to create a CHAP secret. The CHAP secret is a password that is recognized
by the initiator and the target. If you are using mutual authentication to configure the storage array, you must enter the same CHAP
secret that is defined in the host server iSCSI initiator, and you must define a CHAP secret on the target (the storage array) that must be
configured in every iSCSI initiator that connects to the target storage array. For more information about CHAP, see Understanding CHAP
Authentication in the storage array's Deployment Guide.
Initiator CHAP secret
The initiator CHAP secret is set on the host using the iSCSI initiator configuration program provided with the host operating system. If you
are using the mutual authentication method, you must define the initiator CHAP secret when you set up the host. This must be the same
CHAP secret that is defined for the target when defining mutual authentication settings.
Target CHAP secret
If you are using CHAP secrets, you must define the CHAP secret for the target.
Valid characters for CHAP secrets
The CHAP secret must be between 12 and 57 characters. The CHAP secret supports characters with ASCII values of 32-126 decimal. See
the following table for a list of valid ASCII characters.

Changing the iSCSI target identification
You cannot change the iSCSI target name, but you can associate an alias with the target for simpler identification. Aliases are useful
because the iSCSI target names are not intuitive. Provide an iSCSI target alias that is meaningful and easy to remember.
To change the iSCSI target identification:
1. In the AMW, select the Setup tab.
2. Select Manage iSCSI Settings.
The Manage iSCSI Settings window is displayed.
3. Select the Target Configuration tab.
4. Type the alias in iSCSI alias.
5. Click OK.
