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.
Connection results Host settings Port settings
User information
of host Authentication at host
group
Connected if the authentication of the host
succeeded Registered Registered Enabled
Failed to be authenticated and cannot be
connected Not registered Registered Enabled
Failed to be authenticated and cannot be
connected Registered Not registered Enabled
Connected without authentication of the host --- --- Disabled
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.
---: This item does not affect the connection results, or cannot be specified.
Fibre channel switch authentication
When a host attempts to connect to the storage system, the connection results of the authentication
of the fibre channel switch differs depending on the fibre channel switch setting related to each
port.
The following figure illustrates the flow of authentication between fibre channel switch settings and
the connection results. The setting of fibre channel switch authentication is independent from the
setting of host authentication. The connection use cases are detailed below the diagram.
Each case in the flow is explained below.
Authenticating fibre channel switches by ports (Cases A, B, and C)
•
If the user information of the fibre channel switch is registered on the port, and authentication
of the fibre channel switch is enabled (Case A)
Each port authenticates the fibre channel switch. If the authentication of the fibre channel
switch ends successfully, either of the following actions occurs:
◦ When the fibre channel switch is configured for mutual authentication, processing continues
to authentication of the port.
◦ When the fibre channel switch is not configured for mutual authentication, the fibre channel
switch connects to the storage system.
