Running PDM on a Disk Array (CLU)
Predictive Data Migration (PDM) migrates data from the suspect physical drive to a spare drive
before the physical drive fails.
Before you can run PDM, you must have a replacement or target physical drive of adequate capacity
for your disk array.
To run PDM on a disk array:
1. Main Menu >> Disk Array Management
2. Highlight the disk array you want and press Enter.
3. Highlight Background Activities >> Predictive Data Migration and press Enter.
Default source and target drives are shown with possible alternative choices.
4. To choose different drive, highlight the drive, press the backspace key to remove the current
number, then type a new number.
5. Highlight Start and press Enter.
See “Enabling Media Patrol, PDM, and Power Management on a Disk Array (CLU)” on page 58.
For PDM rate, see “Making Background Activity Settings (CLU)” on page 74.
