Running PDM

Predictive Data Migration (PDM) migrates data from the suspect physical drive to
a spare disk drive, similar to Rebuilding. But unlike Rebuilding, PDM acts before
the disk drive fails and your Logical Drive goes Critical.
You an also run PDM on a specific disk array, see "Running PDM on a Disk
Array" on page 124.
