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
Port settings and connection results
The following table shows the relationships between host group settings and the connection results
in authentication of hosts. Unless otherwise noted, connection results are as described regardless
of whether the host is configured for authentication by ports with CHAP.

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.

fabric switch authentication
When a host attempts to connect to the storage system, the connection results of the authentication
of the fabric switch differs depending on the fabric switch setting related to each port.
The following figure illustrates the flow of authentication between fabric switch settings and the
connection results. The setting of fabric switch authentication is independent from the setting of
host authentication. The connection use cases are detailed below the diagram.
