HP XP P9500 Storage - Manual (Page 173)

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.
Settings for authentication of ports (required if performing mutual authentication)
On the storage system, use LUN Manager to specify user information (user name and secret) of
each host group.
On hosts, configure the operating system and fibre channel host bus adapter driver for authenticating
host groups with CHAP. You need to specify the user name and secret of the host group that is the
connection target. For details, see the documentation of the operating system and fibre channel
host bus adapter driver in your environment.
Host and host group authentication
When a host attempts to connect to the storage system, the connection results of the authentication
of the host differ depending on the host group settings.
The following diagram illustrates the flow of authentication of hosts in a fibre channel environment.
The connection uses cases are detailed below the diagram.
Authenticating hosts (Cases A, B, and C)
The following cases describe the examples of performing authentication of host groups
