Reasons to assign ownership of disks and array LUNs

Storage system ownership must be assigned for disks and array LUNs before they become an effective part of your system. You must explicitly assign ownership for array LUNs. Disks can be automatically or manually assigned.

You assign ownership of a disk or array LUN to accomplish the following actions:

• Associate the disk or array LUN with a specific storage system.

  For a stand-alone system, all disks and array LUNs are owned by that system. In an HA configuration, the disks and array LUNs can be owned by either system.

• Enable the disk or array LUN to be used and managed by the system that owns it.

  Unowned disks cannot be used as spares and do not receive the automatic firmware updates that owned disks do.

• Associate the disk or array LUN with a specific SyncMirror pool (when SyncMirror is in use).

  If SyncMirror is not in use, all disks and array LUNs are in pool0.
