The next section explains authentication of hosts and host groups.
Authentication of hosts (Fibre Channel environments)
When a host attempts to connect to the array, the connection results of the authentication of the host
differs depending on the host group settings.
Figure 9 illustrates the relationship between host group
settings and the connection results.

.
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
