RAID Level Virtual Disk State Scenario Result
RAID 6 Degraded (two failed/missing
physical disks)
One bad block on a physical disk. The controller cannot regenerate
data from the peer disks. This
results in a virtual disk bad block.
RAID 6 Ready One bad block on a physical disk. The controller regenerates data
from peer disks and sends a
Write to the bad block. The disk
then remaps the Logical Block
Addressing (LBA) to another
physical location. The problem is
resolved.
Recommendations For Clearing Bad Blocks
Storage Management allows you to clear the bad block warnings. To clear bad blocks, the following procedure is recommended:
1 Perform a backup of the virtual disk with the Verify option selected.
One of the following scenarios may occur:
• Backup operation fails on one or more les. In this case, restore the le from a previous backup. After restoring the le, proceed to
step 2.
• Backup operation completes without error. This indicates that there are no bad blocks on the written portion of your virtual disk.
If you still receive bad block warnings, the bad blocks are in a non-data area. Proceed to step 2.
2 Run Patrol Read and check the system event log to ensure that no new bad blocks are found.
If bad blocks still exist, proceed to step 3. If not, the condition is cleared without the need for step 3.
3 To clear these bad blocks, execute the Clear Virtual Disk Bad Blocks task.
This Clear Virtual Disk Bad Block feature is applicable to PERC H730P MX and PERC H745P MX.
