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
