Registering user information for a host group (for mutual authentication)

You can perform mutual authentication by specifying user information for host groups on the storage system ports. Specify unique user information for each host group. You can change the specified user information for host groups in the same way you initially specify it.

Device Manager - Storage Navigator secondary windows must be defined for use in advance. When you select Modify from the Authentication secondary window to register user information, other users or programs are prevented from changing storage system settings. When you close the secondary window, Modify mode is released. For more information on Device Manager - Storage Navigator secondary windows and Modify mode, see the System Administrator Guide.
