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 for the Fibre Channel switch is registered on the port, but
authentication of the Fibre Channel switch is disabled (Case B):
The ports do not perform authentication of the Fibre Channel switch. The Fibre Channel
switch will connect to the storage system without authentication regardless of whether or
not the Fibre Channel switch is configured for authentication with CHAP.
◦ If the user information for 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.
•
When not performing authentication of Fibre Channel switches by ports (Case D):
The Fibre Channel switch will connect to the storage system without authentication of the host,
regardless of whether or not the Fibre Channel switch is configured for authentication with
CHAP.
In this case, you need not register the user information for the Fibre Channel switch on the
port, but 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 or not the user information for the Fibre Channel switch that attempts to connect is
registered on the port
“Combinations of Fibre Channel settings and connection results” (page 48) shows the relationship
between the combinations of port settings and the connection results in authentication of Fibre
Channel switches. Regardless of whether or not the host is configured for authentication by Fibre
Channel switches with CHAP, the connection results are as follows, unless otherwise noted.

2 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.
Authentication of Ports (Performing Mutual Authentication)
When authentication of a host succeeds, the host performs authentication of the port if required
by the host (mutual authentication). In authentication of ports, when the user information (user name
