Figure H-19: CHAP Authentication Screen
For sessions after CHAP setup, the CHAP Secret is used to authenticate
the Initiator. This has no effect on any session that has already been
established. When CHAP has been disabled, the current session
continues until a restart or a forced log-out of the disk array unit is
executed. After a restart or a forced log-out of the disk array unit, it is no
longer possible to connect to any disk array that requires CHAP
authentication.
The CHAP Secret that is set here is a password that a target uses to
authenticate the Initiator. This password is also required for settings on the
disk array side (see Section: 15.3.21 iSMcfg setldsetchap in the NEC
Storage Manager Command Reference), so be sure to write it down so it is
not forgotten.
