6.7 Verifying a RAID
You can use the RAID Functions Î Verify RAID Set menu option to check the
consistency of parity blocks, i.e. verify that parity information matches the stored
data on the redundant arrays. This is only possible on RAID level 5 or 6; it is not
possible to verify RAIDs created using RAID 0 or RAID 1. During a RAID Verify the
system reads each stripe and checks for valid parity. At the end of the verify
process the system sends an Alert if any stripes were found with invalid parity.
In the Verify RAID Set screen, select the Verify button corresponding to the RAID
to be verified.
It is recommended that you schedule 'RAID Verify' to run periodically to ensure
data availability.
