Specific Settings

[When allowing multiple ports in a multipath configuration or a cluster configuration to recognize
the same LUNs]
Create a LUN Group, and set this same LUN Group to all of the ports.
[If the number of CA ports that connect to the same FC host exceeds eight and the connection target
of the host affinity is Host Group - CA Port Group when connecting to IBM SVCs]
Multiple CA port groups must be created. In this case, a single host group cannot configure host affinity
with multiple CA port groups. Therefore, create host groups with the same settings for the number of CA
port groups that are to be connected when configuring host affinity.
The following is a configuration example of a host affinity that allows FC Host1 and FC Host2 to connect to
16 CA ports and access LunGroup1.
Create two host groups with
identical configurations
[If the one-to-one relationship between the WWNs and Fibre Channel cards cannot be determined]
The host affinity may not be set correctly. In this case, various settings may need to be tried until the serv-
er is able to recognize the ETERNUS DX/AF logical disks.
2.2 Specific Settings
The required settings vary according to the OS and the connection configuration.
Check the various cases described below, and perform any required settings.
2.2.1

Setting the CA Reset Groups

Because all of the ports are configured to be members of one CA reset group in the initial setting, the reset
group settings do not need to be changed.
Create two CA port groups
consisting of eight CA ports
