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.
Alerts 2146 Through 2150 Received While Performing I/O, Consistency Check, Format, Or
Other Operation
If you receive alerts 2146 through 2150 while performing an operation other than a rebuild, replace the damaged disk immediately to
avoid data loss.
Perform the following steps:
1. Back up the degraded virtual disk to a fresh (unused) tape drive.
2. Replace the damaged disk.
3. Perform a rebuild.

A Task Menu Option Is Not Displayed
You may notice that the task menus do not always display the same task options. Some tasks are only valid for certain types of
objects or at certain times. For example, a Check Consistency task can only be performed on a redundant virtual disk. Similarly, if a
disk is already oine, the Oine task option is not displayed.
There may be other reasons why a task cannot be run at a certain time. For example, there may already be a task running on the
object that must complete before additional tasks can be run.
