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
The host connects to the array without authentication of the host regardless of whether or not the
host is configured for authentication by host groups with CHAP.
In this case, although you do not need to register the host's user information on the host group,
you can register the user information.
NOTE:
You should register the 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 host authentication setting.
Figure 10 shows an example of authentication of hosts. In this figure, WWNs of host bus adapters
(HBAs) are abbreviated as a, b, and so on.
