CHAP involves configuring a secret that both your Hitachi Simple Modular
Storage 100 and the host server must know. You enable and configure CHAP
using Storage Navigator Modular 2. CHAP is not enabled by default, but it
is strongly recommended. The Storage Navigator Modular 2 online help
describes how to enable and configure CHAP.
The following sequence describes how CHAP works when it is configured and
enabled on your Hitachi Simple Modular Storage 100.
1. During negotiations between the iSCSI initiator and target, the initiator
sends a “challenge” message to the target.
2. The target responds with a calculated value.
3. The initiator compares the response against its own calculation of the
value. If the values match, the initiator acknowledges the
authentication; otherwise, it terminates the connection.
At random intervals, the initiator sends a new challenge to the target and
repeats steps 1 through 3 to ensure that it is communicating with the
appropriate peer.
