Running Media Patrol on a Disk Array
Media Patrol checks the magnetic media on physical drives. When it finds the

You can schedule Media Patrol to run automatically, see “Scheduling an Activity”
on page 69.
To start Media Patrol:
1. Click the Subsystem icon in Tree View.
2. Click the Disk Arrays icon.

Patrol.

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 256.
To start PDM:
1. Click the Subsystem icon in Tree View.
2. Click the Disk Arrays icon.
