Merge a Physical Drive
The action of merging a physical drive reunites the two portions of a split drive
back into a single physical drive.
The Merge function is not available when either or both portions of the physical
drive are assigned to a logical drive.
To merge a physical drive:
1. Click on the Physical Drive View icon in Tree View.
2. Click on the Merge tab in Management View.
3. Check the box(es) to the left of the physical drive(s) you want to merge.
4. Click the Submit button.
Click on a Physical Drive icon to see the results of your merge operation.
Media Patrol Schedule
The Physical Drive View–Media Patrol tab allows you to start Media Patrol on all
physical drives. You can also run Media Patrol on individual physical drives, see
page 56.
Media Patrol is a routine maintenance procedure that checks the magnetic media
on each disk 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.
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 suspect sector, it will attempt to regenerate the data and
write to the suspect sector. If the write operation is successful, Media Patrol
continues checking other sectors. If the write operation fails, Media Patrol reports
the error to your PC's system log and to the physical drive’s Bad Sector Log (see
page 58). This action triggers a BSL update message and an email message if
you enabled that notification option (see page 38).
