Running PDM on a Logical Drive
Predictive Data Migration (PDM) is the migration of data from the suspect disk drive to a spare drive,
similar to rebuilding a disk array. But unlike rebuilding, PDM automatically copies your data to a spare
drive before the drive fails and your logical drive goes critical.
PDM can be triggered automatically by Media Patrol. See PDM. To run PDM on a logical drive:
1. Click on the Background Activities icon. The list of background activities will appear.
2. Mouse-over PDM, then click the Start button.
3. Choose a Source Physical Drive. The Source Physical Drive is the drive suspected of possible failure.
Source Physical Drives are identified by their disk array and sequence numbers in the disk array.
4. Choose a Target Physical Drive. The Target Physical Drive is the replacement drive. Target Physical
Drives are identified by their physical drive ID number.
5. Click the Confirm button.
Pausing and Resuming PDM
To pause or resume PDM:
1. Click on the Background Activities icon. The list of background activities will appear.
2. Mouse-over PDM, then click the Pause or Resume button.
Stopping PDM
To stop or cancel PDM:
1. Click on the Background Activities icon. The list of background activities will appear.
2. Mouse-over PDM, then click the Stop button.
3. Click the Confirm button.
