The following table shows the host response after new hosts are added.
9.2.2.2 Add iSCSI Host Group
This function creates a new iSCSI host group and registers which hosts are members of this group.
An iSCSI host group uses iSCSI as the interface type, and groups the hosts (HBAs), which access the same LUN
group. This function configures Host Affinity settings for each iSCSI 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 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.
• To assign an appropriate host response to a created host group, refer to "User's Guide -Server Connection-
" for each OS type. The host response configures the operation mode that is appropriate for the host.
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 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 "Example
of changing the host response when adding a host group" (page 447) for details.
