Figure 9 Authentication of hosts (Fibre Channel environments)
Case A to Case D in Figure 9 is explained as follows:
• Case A through Case C: When performing authentication of host groups
• Case A: If the host's user information is registered on the host group, and authentication of
the host is enabled
The host group authenticates the user information sent from the host. If authentication of the host
succeeds, either of the following actions occur:
• When the host is configured for mutual authentication, processing goes to authentication
of the host group.
• When the host is not configured for mutual authentication, the host connects to the array.
If the host is not configured for authentication by host groups with CHAP, the authentication
fails and the host cannot connect to the array.
• Case B: If the host's user information is registered on the host group, but authentication of
the host is disabled
The host group does not perform authentication of the host. The host connects to the array
without authentication regardless of whether or not the host is configured for authentication by
host groups with CHAP.
• Case C: If the host's user information is not registered on the host group
Regardless of the setting on the host, the host group performs authentication of the host, but results
in failure. The host cannot connect to the array.
• Case D: When connecting via a host group that does not perform authentication of hosts
