Figure 12 Authentication of hosts (iSCSI environments)

Case A to Case D in Figure 12 are explained as follows:

• Case A through Case C: When connecting via an iSCSI target that performs authentication of hosts

• Case A: If the host's user information is registered on the iSCSI target, and authentication of

the host is enabled

The iSCSI target 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 iSCSI target.

• When the host is not conﬁgured for mutual authentication, the host connects to the array.

Ifthehostisnotconﬁgured for authentication by iSCSI targets with CHAP, the authentication

failsandthehostcannotconnecttothearray.

• Case B: If the host's user information is registered on the iSCSI target, but authentication of

the host is disabled

The iSCSI target 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

iSCSI targets with CHAP.

CAUTION:

If a host uses Microsoft iSCSI Initiator and is conﬁgured for authentication by iSCSI targets with

CHAP, authentication of the host fails. To allow such a host to connect to the iSCSI target without

authentication, do not conﬁgure it for authentication by ports with CHAP.

• Case C: If the host's user information is not registered on the iSCSI target
