Port Settings And Connection Results; Fabric Switch Authentication - HP XP7 User Manual

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 (
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

of whether the host is configured for authentication by ports with CHAP.

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.

fail. To allow such a host to connect to the port
without authentication, do not configure it for
authentication by ports with CHAP.
