Not only can new RAID groups be created, adding or changing volumes that are registered in existing RAID

groups can also be performed.

storage system

recognized from the server. Select "Standard" for "Type".

Add LUN Group

Create a LUN group (a group of volumes that are recognized from the server, which is

conventionally referred to as an "affinity group").

Correspond the volume number to the Logical Unit Number (LUN) that can be recognized by the

host for each LUN group.

LUN groups are recognized from the server by the host affinity setting that allocates the CA

ports to the LUN groups.

Refer to:

Add LUN Group

Create Host Affinity

To recognize the LUN group from the server, select "All" for the host and allocate the CA port

and the LUN group.
