NOTE: A consistency check scans the data blocks in a RAID level 5 virtual
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
mirrored physical disks. RAID level 0 virtual disks have no data consistency.

NOTE: A background media scan is the lowest priority of the long-running
operations.
To suspend a media scan:

2 Select Virtual Disk Change Media Scan Settings.
The Change Media Scan Settings window is displayed.
