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.
Figure 9 Authentication of hosts (Fibre Channel environments)
Case A to Case D in Figure 9 is explained as follows:
• Case A through Case D: 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
