The 3ware RAID controller checks the backup DCB, even when the primary
DCB is OK. If an error is found, the controller will attempt to correct the error
by reading the primary copy. If the primary copy is valid, the backup DCB
will be rewritten to rectify the errors.
Action
LSI recommends verifying the unit. See "Starting a Verify Manually" on
page 152.
