HP XP Array Manager Software - Manual (Page 44)

• On the storage system:
Use LUN Manager to specify whether to perform authentication of 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. For
details on the settings, see “ Enabling or Disabling Host Authentication ” on page 49 and
“ Registering Host User Information ” on page 50.
• 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 for 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 for the operating system and Fibre
Channel host bus adapter driver in your environment.
When authentication of a host succeeds, the host performs authentication of the port reversely if required
by the host (mutual authentication). In authentication of ports, when the user information (user name
and secret) of the port specified on the port side matches that stored on the host, the host allows the
host group to connect.
Host and Host Group Authentication
When a host attempts to connect to the storage system, the connection results of the authentication of
the host differs depending on the host group settings. Figure 23 on page 45 illustrates the relationship
between host group settings and the connection results in a flow.
