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.
