the iSCSI target. A secret is a password used in CHAP authentication. When registering user
information, you can also enable or disable authentication on a host basis. For more information
about the settings, see Enabling and disabling authentication of hosts on iSCSI targets and
Registering a host's user information on an iSCSI target.
• On hosts:
Configure the operating system and iSCSI driver for authentication by iSCSI targets with CHAP.
You must specify the host's user name and secret used for CHAP. For more information, see
the documentation for the operating system and iSCSI driver in your environment.
• Settings for authentication of ports (required if performing mutual authentication)
• On the array:
Use XP LUN Configuration and Security Manager Software to specify each iSCSI target's user
information (user name and secret). For more information about the settings, see Specifying
an iSCSI target's user information (when performing mutual authentication).
• On hosts:
Configure the operating system and iSCSI driver for authenticating iSCSI targets with CHAP.
You must specify the user name and secret of the iSCSI target that is the connection target. For
more information, see the documentation for the operating system and iSCSI driver in your
environment.
The next section explains authentication of hosts and iSCSI targets.
Authentication of hosts (iSCSI environments)
When a host attempts to connect to the array, the connection results of the authentication of the host
differ depending on the iSCSI target settings. Figure 12 illustrates the relationship between iSCSI
target settings and the connection results.
