LUN group. The Host Affinity is specified for each FC host group.
The number of host groups and hosts that can be registered
*1: The total number of host groups irrespective of the interface types.
*2: The total number of hosts irrespective of the interface types.

Registration of the host is necessary to create a host group. Create a new host group when registering a
host with ETERNUS Web GUI by using this function.
•
A host can be a member of several host groups. However, only one LUN group can be allocated to host
and port combinations when configuring host affinity.
•
Refer to "FUJITSU Storage ETERNUS DX Configuration Guide -Server Connection-" for each OS type to assign
an appropriate host response to the created host group. A host response has a recommended patterns
which has been prepared for each OS type. Refer to
"Recommended patterns of host responses" (page
for details. If an appropriate host response is not configured to the host group, the path may not be
switched correctly or the volume may not be recognized correctly.
•
The host response that is specified for a host group is applied to all the member hosts in the target group.
When a host belongs to multiple host groups, the same host response must be applied for all the groups
to which the target host belongs. When a host that already belongs to an existing host group is added to
a newly created host group, the host response of the new host group is applied to the host. The host
response of the existing host group to which the target host belongs is also changed. Refer to
of changing the host response when adding a host group" (page 370)
for details.
•
