Physical Disk Is Offline Or Displays An Error Status
A physical disk may display an error status if it has been damaged, is offline, or was a member of a virtual
disk that has been deleted or initialized. The following actions may resolve the error condition:
• If a user has changed the status to Offline, then return the disk to Online status by executing the
Online disk task.
• Rescan the controller. This action updates the status of storage objects attached to the controller. If
the error status was caused by deleting or initializing a virtual disk, rescanning the controller should
resolve this problem.
• Investigate whether there are any cables, enclosure, or controller problems preventing the disk from
communicating with the controller. If you find a problem and resolve it, you may need to rescan the
controller to return the disk to Online or Ready status. If the disk does not return to Online or Ready
status, reboot the system.
• If the disk is damaged, replace it.

Replacing A Failed Disk
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.
Alerts 2146 Through 2150 Received During A Rebuild Or While A Virtual Disk
Is Degraded
Perform the following steps:
1. Replace the damaged physical disk.
2. Create a new virtual disk and allow the virtual disk to completely resynchronize.
While the resynchronization is in progress, the status of the virtual disk is Resynching.
3. Restore data to the virtual disk from the backup.
