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.

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.

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

  1. From the Manage page, select the storage array that contains the volumes for which you want to change the controller ownership.
  2. Select Provisioning > Manage Volumes.
  3. 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.
  4. 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.
  • The system 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.
