authentication, see Table B-3.
Step 5: Configure CHAP Authentication on the
Storage Array (Optional)
If you are configuring CHAP authentication of any kind (either target-only or
target and mutual), you must complete this step and "Step 5: Configure
CHAP Authentication on the Storage Array (Optional)" on page 63.
If you are not configuring any type of CHAP, skip these steps and go to "Step
7: Connect to the Target Storage Array From the Host Server" on page 69.
NOTE: If you choose to configure mutual CHAP authentication, configure target
CHAP first.
In terms of iSCSI configuration, the term target always refers to the storage array.

CHAP Type Description
Target CHAP Sets up accounts that iSCSI initiators use to connect to the
target storage array. The target storage array then authenticates
the iSCSI initiator.
Mutual CHAP Applied in addition to target CHAP, mutual CHAP sets up an
account that a target storage array uses to connect to an iSCSI
initiator. The iSCSI initiator then authenticates the target.
