Dell MD3220, MD3200 Configure Chap Authentication on the Storage Array Optional, Chap Definitions

CHAP Definitions

To summarize the differences between target CHAP and mutual CHAP authentication, see Table B-3.

Table B-3. CHAP Types Defined

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.

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.

1From MDSM, click the iSCSI tab and then click Change Target Authentication.

Select one of the CHAP settings described in Table B-4.
