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 111.

To start Media Patrol:

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

Media Patrol.

5. Click the Start button.

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.
