Setting Up CHAP
The next two steps in your iSCSI configuration, "Configuring CHAP
Authentication on the Storage Array (Optional)" on page 58 and
"Configuring CHAP Authentication on the Host Server (Optional)" on
page 59, offer step-by-step procedures for setting up CHAP on your storage
array and host server.
Configuring CHAP Authentication on the Storage Array (Optional)
If you are configuring target-only CHAP authentication, complete "Configuring
Target CHAP Authentication on the Storage Array" on page 58 and "Configuring
CHAP Authentication on the Host Server (Optional)" on page 59.
If you are configuring mutual CHAP authentication, complete "Configuring
Mutual CHAP Authentication on the Storage Array" on page 59 and
"Configuring CHAP Authentication on the Host Server (Optional)" on page 59.
If you are not configuring any type of CHAP, skip to "Connect to the Target
Storage Array From the Host Server" on page 61.
NOTE: If you choose to configure mutual CHAP authentication, you must first
configure target CHAP.
Remember, in terms of iSCSI configuration, the term target always refers to
the storage array.
Configuring Target CHAP Authentication on the Storage Array
1 From MD Storage Manager, click the iSCSI tab and then Change Target
Authentication
.
Make a selection based on the following:
Table 3-5. CHAP Settings
Selection Description
None This is the default selection. If None is the only selection, the
storage array will allow an iSCSI initiator to log on without
supplying any type of CHAP authentication.
None and CHAP The storage array will allow an iSCSI initiator to log on with or
without CHAP authentication.
CHAP If CHAP is selected and None is not selected, the storage array
will require CHAP authentication before allowing access.
