Setting Up Your iSCSI Storage Array
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.
1 From MD Storage Manager, click on the iSCSI tab, then select Enter Mutual Authentication
Permissions.
2 Select an initiator on the host server and click the CHAP Secret.
3 Enter the Initiator CHAP secret, confirm it in Confirm initiator CHAP secret, and click OK.
NOTE:
In some cases, an initiator CHAP secret may already be defined in your configuration. If so, use it
here.
4 Click Close.
NOTE:
To remove a CHAP secret, you must delete the host initiator and re-add it.
