You can schedule Media Patrol to run automatically, see “Scheduling an Activity”
on page 139.

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.
The target physical drive must be the same media type, HDD or SDD, as the
other physical drives in the disk array.
See “Predictive Data Migration (PDM)” on page 255.
To start PDM:
1. Click the Subsystem icon in Tree View.
2. Click the Disk Arrays icon.
