Description
What is a media scan?


Steps to Follow

A media scan is a background process that runs on all volumes in the Storage Array for
which it has been enabled and provides error detection on the drive media. The advantage
of enabling the media scan process is that the process can find media errors before they
disrupt normal drive reads and writes. The media scan process scans all volume data to
verify that it can be accessed and if you enable redundancy check it scans the volume
redundancy data at the same time.

Volumes with redundancy protection – Data is reconstructed, rewritten to the drive, and verified. The error is reported to the Event Log

Volumes without redundancy protection – The error is not corrected but is reported to the Event Log.  Volumes without redundancy protection include RAID 0 volumes and degraded RAID Level 1, RAID Level 3, RAID Level 5, and RAID Level 6 volumes.
