Enabling Media Patrol, PDM, and Power Management on a
Disk Array (CLU)
Media Patrol checks the magnetic media on physical drives. Predictive Data Migration (PDM)
migrates data from the suspect physical drive to a spare drive
before the physical drive fails. Power
Management parks the heads, spins down, and stops rotation after a set period of time to reduce
power consumption.
