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.
