Switch authentication – HP XP Array Manager Software User Manual
Page 47
The user information for Host B is also registered on host group 1, but the authentication setting is
disabled. Therefore, Host B can connect to the storage system without authentication.
The user information for Host C is not registered on 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 host group 2, which 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 by the combination of the following
host group settings:
•
Setting of the host group in the Port tree: enable ( ) or disable ( )
•
Whether or not the user information for the host that attempts to connect is registered on the
host group
on page 47 shows the relationship between the combinations of host group settings and the
connection results in authentication of hosts. Regardless of whether or not the host is configured for
authentication by ports with CHAP, the connection results are as follows, unless otherwise noted.

* If a host is configured for authentication by ports with CHAP, authentication of the host will fail. To
allow such a host to connect to the port without authentication, do not configure it for authentication by
ports with CHAP.
Switch Authentication
When a host attempts to connect to the storage system, the connection results of the authentication
of the Fibre Channel switch differ depending on the Fibre Channel switch setting related to each
port.
on page 48 illustrates the relationship between Fibre Channel switch settings and the
connection results in a flow. The setting of Fibre Channel switch authentication is independent from the
setting of host authentication.
