13.3.2 Mutual Authentication

With Mutual Authentication, a CHAP secret is configured that a specific initiator must use it to
get access to the storage subsystem. That is also called initiator authentication or
bi-directional authentication. Each initiator can have its own CHAP secret.
Do the following steps:
1. In the Manage iSCSI Settings window (Figure 13-2 on page 321), select the Mutual
Authentication tab.
2. In the tab as in Figure 13-4 on page 323 select a host port that has already been defined,
as described in 13.7.2, "Defining new iSCSI host" on page 334. The host port is referred to
as Initiator Label. In this example there is no CHAP secret defined (No permissions
entered) for this initiator, as shown in the last column - "Permission Set?". Click CHAP
Secret.
