Hosts can be added to host groups which the host affinity setting has been already configured, or
deleted from host groups.
If a host is added, the host affinity setting is automatically configured to the host, as a host group
member.
If a host is deleted, the host affinity setting is cleared from the corresponding host.
•
The maximum number of connectable hosts (the number of HBAs) per device is 1024,
irrespective of the interface types.
•
The maximum number of connectable hosts (the number of HBAs) per CA port is 256.

Registration of the host is necessary to create a host group. Not all of
the hosts can be deleted from a host group. A host, which has been
registered on GUI, belongs to one of the host groups.

Assign an appropriate host response to the host group. The host
response configures the operation mode which is appropriate to 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.

When a host was added to a host group, of which the host affinity

affinity setting and the added host will be configured. To modify the path
between a host and a port, refer to
