Appendix—Manual Configuration of iSCSI 65
Configuring Target CHAP Authentication on the Storage Array
1 From MDSM, click the iSCSI tab and then click Change Target
Authentication.
Select one of the CHAP settings described in Table A-4.
2 To configure a CHAP secret, select CHAP and select CHAP Secret.
3 Enter the Target CHAP Secret (or Generate Random Secret). Confirm it
in Confirm Target CHAP Secret and click OK.
Although the storage array allows sizes from 12 to 57 characters, many
initiators only support CHAP secret sizes up to 16 characters (128-bit).
NOTE: A CHAP secret is not retrievable after it is entered. Ensure that you
record the secret in an accessible place. If Generate Random Secret is used,
copy and paste the secret into a text file for future reference since the same
CHAP secret is used to authenticate any new host servers you may add to the
storage array. If you forget this CHAP secret, you must disconnect all existing
hosts attached to the storage array and repeat the steps in this chapter to
re-add them.
4 Click OK.
Table A-4. CHAP Setting

storage array allows an iSCSI initiator to log on without

None and CHAP The storage array allows an iSCSI initiator to log on with or
without CHAP authentication.
CHAP If CHAP is selected and None is deselected, the storage array
