Maintaining and Managing Storage Configurations : Running a Consistency Check

Running a Consistency Check

You should periodically run a consistency check on fault-tolerant virtual drives (RAID 1, 5, 6, 10, 50, or 60 configurations; RAID 0 does not provide data redundancy). A consistency check scans the virtual drive to determine whether the data has become corrupted and needs to be restored.

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 must run a consistency check if you suspect that the data on the virtual drive might be corrupted.

NOTE Make sure to back up your 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. The following sections explains how to:
