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 before the disk drive fails and your Logical Drive goes Critical.

See “Predictive Data Migration (PDM)” on page 184. To start PDM:

1.Click the Subsystem icon in Tree View.

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.
