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.
-
From the Manage page, select the storage array that contains the volumes for which you want to change the controller ownership.
-
Select .
-
Select any volume, and then select .
The Change Volume Ownership dialog box appears. All volumes on the storage array appear in this dialog box.
-
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.
