This is a general Topic for the Vess A-Series to start Media Patrol.

Before we start here is an explanation, what is Media Patrol?

Media Patrol is a routine maintenance procedure that checks 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.

If Media Patrol encounters a critical error, it triggers PDM if PDM is enabled.
