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 alerts 2146 through 2150 as the result of performing a rebuild or while the virtual disk is in a degraded state, then data cannot be recovered from the damaged disk without restoring from the 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.
