Host D is attached to host group 2, which does not perform authentication of hosts. Therefore, Host D can
connect to the array without authentication.
Authentication of Fibre Channel switches
When a host attempts to connect to the array, the connection results of the authentication of the Fibre
Channel switch differs depending on the Fibre Channel switch setting related to each port. Figure 11
illustrates the relationship between Fibre Channel switch settings and the connection results. The Fibre
Channel switch authentication setting is independent from the host authentication setting.
Figure 11 Authentication of Fibre Channel switches
Case A to Case D in Figure 11 are explained as follows:
• Case A through Case C: When performing authentication of Fibre Channel switches by ports
• Case A: If the Fibre Channel switch’s user information is registered on the port, and authentication
of the Fibre Channel switch is enabled
Each port authenticates the Fibre Channel switch. If the authentication of the Fibre Channel switch
succeeds, either of the following actions occur:
• When the Fibre Channel switch is configured for mutual authentication, processing goes to
authentication of the port.
• When the Fibre Channel switch is not configured for mutual authentication, the Fibre Channel
switch connects to the array.
If the port’s Fibre Channel switch is not configured for authentication with CHAP, the authentication
fails and the Fibre Channel switch cannot connect to the array.
• Case B: If the Fibre Channel switch’s user information is registered on the port, but authentication
of the Fibre Channel switch is disabled
