Working with Disksets
Displaying the Owner
The owner attribute indicates the name of the controller that owns
the diskset. When you create a diskset, diskset ownership is
assigned by default to the controlling partner. The controller on the
owning node is in charge of managing container and partition
operations for disks in the diskset. When a disk on a shared channel
is not owned by either node in a cluster, you cannot perform
container operations on the disk.
In a cluster environment, a controller can be a controlling partner or
a peer partner. The controlling partner is the controller that you
opened with the
open command.
The peer partner is the controller that resides in the cluster along
with the controlling partner. The
open command automatically
opens the peer partner when you open the controlling partner.
You assign ownership to either the controlling partner or the peer
partner when you create the diskset. See the Creating a Diskset on
page 5-11 for further information on creating a diskset. You change
ownership of a diskset using the
disk_set forceownerchip
command, disk_set releaseownerchip command, and the
disk_set takeownerchip command. See Changing Ownership of
a Diskset on page 5-21 for information on these commands.
To display the controller that owns a diskset, use the disk_set
list command, as in the following example. In the example, the
Owner column indicates that controller \\.\HPN0 owns the
diskset.
