The user name the initiator uses to authenticate the storage system. This value is optional for CHAP authentication.
Providing an outbound user name and password enables birdirectional authentication between the initiator and the filer.
Note: The outbound user name and password you specify for this storage must match the inbound user name and password in the initiator's CHAP configuration. You cannot use the same user name and password for inbound and outbound settings on the storage system.
