Add SAS Host
This function creates a new SAS host group, and registers the host to be a member.
A SAS host group uses SAS as the interface type, and groups the hosts (HBAs), which access
the same LUN group. This function configures Host Affinity settings for each SAS host group.
•
The maximum number of host groups per device is 128, irrespective of the interface types.
•
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.
•
The maximum number of connectable hosts (the number of HBAs) per host group is 8.

Click the [Continue] button to continue registering iSCSI host groups.
•
Registration of the host is necessary to create a host group. Create a
new host group when registering a host on GUI.
•
One host cannot be a member of several host groups.
•
Assign an appropriate host response to the created 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.
