Change controller ownership of a volume

You can change the preferred controller ownership of a volume, so that I/O for host applications is directed through the new path.

Before you begin

If you do not use a multipath driver, any host applications that are currently using the volume must be shut down. This action prevents application errors when the I/O path changes.

About this task

You can change controller ownership for one or more volumes in a pool or volume group.

Procedure

  1. Select Storage > Volumes.
  2. Select any volume, and then select More > Change ownership.
    The Change Volume Ownership dialog box appears. All volumes on the storage array appear in this dialog box.
  3. Use the Preferred Owner drop-down list to change the preferred controller for each volume that you want to change, and confirm that you want to perform the operation.
