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.
What happens next?
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.
