Running PDM on a Disk Array
Predictive Data Migration (PDM) migrates data from the suspect physical drive to
a spare physical drive, similar to Rebuilding. But unlike Rebuilding, PDM acts

the disk drive fails and your Logical Drive goes Critical.

2. Click the Disk Arrays icon.
3. Click the Disk Array icon.
4. From the dropdown menu on the Background Activities tab, choose Start
PDM
.
5. In the next screen, choose the Source and Target physical drives.
The suspect physical drive is the Source. The replacement physical drive is
the Target.
6. Click the Start button.
