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. The Host Affinity is specified for each iSCSI host group.

*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
472) 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)
• Unlike ETERNUS Web GUI, ETERNUS CLI can register two iSCSI hosts that have the same iSCSI name by
setting an IP address for one of these iSCSI hosts and by not setting an IP address for the other iSCSI host.
However, if iSCSI hosts are registered in the ETERNUS DX in this way, iSCSI hosts cannot be added using
ETERNUS Web GUI. Avoid this configuration when using ETERNUS Web GUI and ETERNUS CLI together. If
both iSCSI hosts already exist, use ETERNUS CLI to specify an IP address for the iSCSI host without the IP
address.
