10.2 Running a Consistency
Check
The Consistency Check operation verifies correctness of the data in virtual drives that
use RAID levels 1, 5, 6, 10, 50, and 60. (RAID 0 does not provide data redundancy). For
example, in a system with parity, checking consistency means computing the data on
one drive and comparing the results to the contents of the parity drive.
You should run a consistency check on fault-tolerant virtual drives periodically. You
must run the consistency check if you suspect that the virtual drive data might be
corrupted. Be sure to back up the data before running a consistency check if you think
the data might be corrupted.
To run a consistency check, first set the consistency check properties and then
schedule the consistency check. This section explains how to set the properties,
schedule the check, and run the consistency check.
