Canceling A Rebuild
Does my controller support this feature? See Supported Features.
Select the Cancel Rebuild task to cancel a rebuild that is in progress. If you cancel a rebuild, the virtual disk remains in a Degraded state. The failure of an additional physical disk can cause the virtual disk to fail and may result in data loss. It is recommended that you rebuild the failed physical disk as soon as possible.
- NOTE: If you cancel the rebuild of a physical disk that is assigned as a hot spare, reinitiate the rebuild on the same physical disk in order to restore the data. Canceling the rebuild of a physical disk and then assigning another physical disk as a hot spare does not cause the newly assigned hot spare to rebuild the data. Reinitiate the rebuild on the physical disk that was the original hot spare.
