The authentication method you want to choose. Select from the following methods:
none傍here is no authentication for the initiator.
deny傍he initiator is denied access when it attempts to authenticate to the storage system.
CHAP傍he initiator logs in using a Challenge Handshake Authentication Protocol (CHAP) user name and password. You can specify a CHAP password or generate a random password. There are two types of CHAP user names and passwords:
Inbound傍he storage system authenticates the initiator. Inbound settings are required if you are using CHAP authentication.
Outbound傍his is an optional setting to enable the initiator to authenticate the storage system. You can use outbound settings only if you defined an inbound user name and password on the storage system.
In CHAP authentication, the storage system sends the initiator a challenge value. The initiator responds with a value calculated using a "one-way hash" function. The storage system then checks the response against its own version of the value calculated using the same one-way hash function. If the values match, the authentication is successful.
