Thehostwillconnect to thestorage system withoutauthenticationofthe host, regardlessof

whetherornot thehostisconﬁgured for authentication by host groups with CHAP.

In this case, you need not register the user information for the host on the host group, but you

can register it.

Notes:

You should register user information for all hosts to be connected to a host group that performs

authentication of hosts. To allow a speciﬁc host to connect to such a host group without authentication,

conﬁgure the host group and the host as follows:

On the host group: Register the user information for the host you want to allow to connect without

authentication, and then, disable the authentication setting of the host.

Figure 24 on page 46 shows an example of authentication of hosts. In this ﬁgure, WWNs of host bus

adapters (HBAs) are abbreviated as a, b,and so on.

Figure 24 Example of Authentication of Hosts

In Figure 24 on page 46, host group 1 performs authentication of hosts, but host group 2 does not.

The user information for Host A is registered on host group 1, and the authentication setting is enabled.

Therefore, if authentication of the host is successful, Host A can connect to the storage system (or,

the processing goes on to the authentication of the host group). As a precondition of successful

authentication, Host A should be conﬁgured for authentication by host groups with CHAP.
