Receive a “Bad Block” Alert with “Replacement,” “Sense,” or

“Medium” Error

The following alerts or events are generated when a portion of a physical disk

is damaged:

• 2146

• 2147

• 2148

• 2149

• 2150

This damage is discovered when the controller performs an operation that

requires scanning the disk. Examples of operations that may result in these

alerts are as follows:

• Consistency check

•Rebuild

•Virtual disk format

•I/O

If you receive an alerts 2146 through 2150 as the result of doing a rebuild or

while the virtual disk is in a degraded state, then data cannot be recovered

from the damaged disk without restoring from backup. If you receive alerts

2146 through 2150 under circumstances other than a rebuild, then data

recovery may be possible. The following describes each of these situations.
