Configuring Mutual CHAP Authentication on the Storage Array
The initiator secret must be unique for each host server that connects to the
storage array and must not be the same as the target CHAP secret.
Change the initiator authentication settings in the Change Target
Authentication window. Use these options to change the settings:
• None—Select None if you permit no initiator authentication. If you select
None, any initiator can access this target. Use this option only if you do
not require secure data. However, you can select both
None and CHAP at
the same time.
•
CHAP—Select CHAP if you want to enable an initiator that tries to
access the target to authenticate using CHAP. Define the CHAP secret
only if you want to use mutual CHAP authentication. If you select
CHAP,
and if no CHAP target secret is defined, an error message is displayed.
Click
CHAP Secret to view the Enter CHAP Secret windows. Use this
window to define the CHAP secrets.
NOTE:
To remove a CHAP secret, you must delete the host initiator and re-add it.

Host Server (Optional)
