To enable CHAP authentication

1        Configure CHAP authentication on all iSCSI targets accessed by the Unitrends system.

2        In the Unitrends system, select Settings > Storage and Retention > iSCSI CHAP Credentials.

3        Enter credentials in the Username, Password, and Verify Password fields, then click Save CHAP credentials. One set of credentials is used to access all iSCSI targets.

     By default, Username contains the backup system’s iSCSI qualified name (IQN). It is required that the username and password on the initiator (backup system) match those defined on the targets. Modify the Username entry if necessary.

     The password must be 12-16 characters in length.
