On the storage system, use LUN Manager to specify whether to authenticate hosts on each host group.

On a host group that performs authentication, register user information (group name, user name, and secret) of the hosts that are allowed to connect to the host group. A secret is a password used in CHAP authentication. When registering user information, you can also specify whether to enable or disable authentication on a host basis.

On hosts, configure the operating system and Fibre Channel host bus adapter driver for authentication by host groups with CHAP. You need to specify the user name and secret of the host used for CHAP. For details, see the documentation of the operating system and Fibre Channel host bus adapter driver in your environment.
