Performing Preventative Measures on Disk Drives and VDs

The following drive and VD-level operations help to proactively detect disk drive and VD errors that
could potentially cause the failure of a controller node. For more information about these operations, refer
to the Intel(R) RAID Software User's Guide.

Patrol Read – A patrol read periodically verifies all sectors of disk drives that are connected to a
controller, including the system reserved area in the RAID configured drives. You can run a patrol
read for all RAID levels and for all hot spare drives. A patrol read is initiated only when the
controller is idle for a defined time period and has no other background activities.
 Consistency Check – You should periodically run a consistency check on fault-tolerant virtual drives
(RAID 1, RAID 5, RAID 6, RAID 10, RAID 50, and RAID 60 configurations; RAID 0 does not
provide data redundancy). A consistency check scans the virtual drives to determine whether the data
has become corrupted and needs to be restored.
For example, in a VD with parity, a consistency check computes the data on one drive and compares
the results to the contents of the parity drive. You must run a consistency check if you suspect that
the data on the VD might be corrupted.
NOTE: Be sure to back up the data before running a consistency check if you think the data might be
corrupted.
