HP XP P9500 Storage - Manual (Page 153)

If the fibre channel switch of the port is not configured for authentication with CHAP, the
authentication fails and the fibre channel switch cannot connect to the storage system.
•
If the user information of the fibre channel switch is registered on the port, but authentication
of the fibre channel switch is disabled (Case B)
Each port does not perform authentication of the fibre channel switch. The fibre channel switch
connects to the storage system without authentication regardless of whether the fibre channel
switch is configured for authentication with CHAP.
•
If the user information of the fibre channel switch is not registered on the port (Case C)
Regardless of the setting on the fibre channel switch, the port performs authentication of the
fibre channel switch, but results in failure. The fibre channel switch cannot connect to the
storage system.
Not authenticating fibre channel switches by ports (Case D)
The fibre channel switch connects to the storage system without authentication of the host regardless
of whether the fibre channel switch is configured for authentication with CHAP. In this case, though
you need not register the user information of the fibre channel switch on the port, you can register
it.
During authentication of hosts, the connection result is determined depending on the combination
of the following port settings:
•
Setting of the port in the Port tree: enable ( ) or disable ( )
•
Whether the user information of the fibre channel switch that attempts to connect is registered
on the port
Fibre channel switch settings and connection results
The following table shows the relationship between the combinations of port settings and the
connection results in authentication of fibre channel switches. Unless otherwise noted, connection
results are as described regardless of whether the host is configured for authentication by fibre
channel switches with CHAP.

If a fibre channel switch is configured for
authentication by ports with CHAP, authentication
of the host will fail. To allow such a fibre channel
switch to connect to the port without authentication,
do not configure it for authentication by ports with
CHAP.
