Figure 23 Flow of Authentication of Hosts (In a Fibre Channel environment)

Each case in the ﬂow is explained as follows. Case A to Case D in Figure 23 on page 45 corresponds

that below.

• When performing authentication of host groups

• If the user information for the host is registered on the host group, and authentication of the

host is enabled (Case A):

The host group authenticates the user information sent from the host. If the authentication of

the host successes, either of the following actions occur:

• When the host is conﬁgured for mutual authentication, the processing will go on to

authentication of the host group.

• When the host is not conﬁgured for mutual authentication, the host will connect to the

storage system.

If the host is not conﬁgured for authentication by host groups with CHAP, the authentication

fails and the host cannot connect to the storage system.

• If the user information for the host is registered on the host group, but authentication of the

host is disabled (Case B):

The host group does not perform authentication of the host. The host will connect to the

storage system without authentication, regardless of whether or not the host is conﬁgured for

authentication by host groups with CHAP.

• If the user information for the host is not registered on the host group (Case C):

Irrespective of the setting on the host, the host group performs authentication of the host, but

results in failure. The host cannot connect to the storage system.

• When connecting via a host group that does not perform authentication of hosts (Case D):
