144 Configuration: Disk Groups and Virtual Disks
The media scan duration specifies the number of days for which the media
scan runs on the selected virtual disks.
5 To disable media scans on an individual virtual disk, select the virtual disk
in the Select virtual disks to scan area, and deselect Scan selected virtual
disks.
6 To enable media scans on an individual virtual disk, select the virtual disk
in the Select virtual disks to scan area, and select Scan selected virtual
disks.
7 To enable or disable the consistency check, select either With consistency
check or Without consistency check.

disk, or a RAID level 6 virtual disk and checks the consistency information for
each block. A consistency check compares data blocks on RAID level 1
replicated physical disks. RAID level 0 virtual disks have no data consistency.
