Behavior
If cache data for a LUN exists on a particular
controller, the unit will be brought online there.
Otherwise, the units are brought online to
Controller B.
All LUNs are brought online to the surviving
controller.
All LUNs remain on the surviving controller.
After controller restoration, the units that are
online to Controller A and set to Path B are
brought online to Controller B. This is a one
time occurrence. If the host then moves the LUN
using SCSI commands, the LUN will remain
where moved.
