Registration of the host is necessary to create a host group. It is not possible to delete all hosts from a
host group.
•
A host that has been registered with ETERNUS Web GUI by using this function belongs to one of the host
groups.
•
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 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 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
another host group, the host response of the target host is changed to the host response of the host
group to which the target host is added. 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 to an
existing host group" (page 371)
for details.
•
When changing the host response for the host group, the host responses of the other host groups to
which the target host belongs are also changed.
•
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 host settings cannot be
changed 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.
