Physical Drive Media Patrol
Media Patrol is a routine maintenance procedure that che cks the magnetic media
on each disk drive. Media Patrol checks all physical drives assigned to disk
arrays. Media Patrol does not check unconfigured drives.
Media Patrol will also check spare drives, if those drives have Media Patrol
enabled. Media Patrol for spare drives is enabled by default. You can disable it in
VTrak's Command Line Interface (CLI).
Unlike Synchronization and Redundancy Check, Media Patrol is concerned with
the condition of the media itself, not the data recorded on the media. If Media
Patrol encounters a critical error, it triggers PDM if PDM is enabled.
To run Media Patrol, do the following:
1. Click the Subsystem icon in Tree View.
2. Click on the Background Activities tab in Management View.
3. From the Background Activities dropdown menu, select Start Media Patrol.
4. Click the Start button.
To set Media Patrol priority, see “Change Background Settings” on page71.
