● Virtual disk format

● I/O

● Patrol Read

Recovering a physical disk bad block depends on the RAID level and state of the virtual disk. If a virtual disk is redundant, the

controller can recover a bad block on a physical disk. If a virtual disk is not redundant, then the physical disk bad block results in

a virtual disk bad block.

Table 36. Sample Scenarios For Virtual Disk Bad Blocks

RAID Level Virtual Disk State Scenario Result

RAID 0 Degraded One bad block on a physical

disk.

The controller cannot

regenerate data from the

peer disks as there is no

redundancy. This results in a

virtual disk bad block.

RAID 5 Ready One bad block on a physical

disk.

The controller regenerates

data from the 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.

RAID 5 Degraded One bad block on a physical

disk.

The controller cannot

regenerate data from the peer

disks because one drive is

missing. This results in a

virtual disk bad block.

RAID 5 Ready One bad block on two physical

disks at the same location.

The controller cannot

regenerate data from the peer

disks. This results in a virtual

disk bad block.

RAID 6 Partially degraded (one failed/

missing physical disk)

One bad block on a physical

disk.

The controller regenerates

data from the peer disks

and sends a Write to the

bad block. The disk then

remaps the LBA to another

physical location. The problem

is resolved.

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:
