Running PDM
Predictive Data Migration (PDM) migrates data from the suspect physical drive to
a spare physical drive before the disk drive fails.
Before you can run PDM, you must have a replacement or target physical drive of
adequate capacity for your disk array.
Notes
You can add physical drives to a RAID 50 or 60 array but you
cannot change the number of axles.
If you add an odd number of physical drives to a RAID 10
array, it becomes a RAID 1E array by default.
