HP XP P9500 Storage - Manual (Page 151)

In the example, host group 1 performs authentication of hosts, and host group 2 does not.
The user information of host A is registered on the host group 1, and the authentication setting is
enabled. Therefore, if the 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
.
The user information of host B is also registered on the host group 1, but the authentication setting
is disabled. Therefore, host B can connect to the storage system without authentication.
The user information of host C is not registered on the host group 1. Therefore, when host C tries
to connect to the storage system, the authentication fails and the connection request is denied
regardless of the setting on host C.
Host D is attached to the host group 2 that does not perform authentication of hosts. Therefore,
host D can connect to the storage system without authentication.
During authentication of hosts, the connection result is determined depending on the combination
of the following host group settings:
•
Setting of the host group in the Port tree: enable ( ) or disable ( )
•
Whether the user information of the host that attempts to connect is registered on the host
group
