Physical Drive Media Patrol
The Physical Drive–Media Patrol tab allows you to start Media Patrol on an
individual physical (disk) drive. You can also run Media Patrol on all physical
drives at the same time, see page60.
Media Patrol is a routine maintenance procedure that checks the magnetic media
on each physical drive, sector by sector. Media Patrol checks physical drives
assigned to logical drives, spare drives and currently unassigned physical drives
that were once part of a logical drive or a spare. Media Patrol does not check new
physical drives that have never been configured nor physical drives assigned as
JBOD.
