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.

  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.

What happens next?

  • System Manager changes the controller ownership of the volume. I/O to the volume is now directed through this I/O path.

  • The volume might not use the new I/O path until the multipath driver reconfigures to recognize the new path. This action usually takes less than five minutes.
