Enabling Single-Direction Chap During Discovery Session And Normal Session; Chap Single-Direction Settings - HP StorageWorks MPX200 User Manual

• Single-direction—The target authenticates the identity of the initiator with the user-provided CHAP
secret. To enable single-direction CHAP, you must enable CHAP for a specific initiator record on
the MPX200 and enter a corresponding CHAP secret from the iSCSI host.
• Bidirectional—The initiator and target authenticate each other's identity by using the user-provided
CHAP secrets. To enable bidirectional CHAP for a discovery session, you must provide a CHAP
secret for the initiator and for the iSCSI port for which you are performing discovery. To enable
bidirectional CHAP for a normal session, you must provide a CHAP secret for the initiator and for
the iSCSI-presented target that you want to log in to.
