Automatically Rebuilding the Defunct Drive

Automatically Rebuilding the Defunct Drive

The ServeRAID adapter/controller will rebuild a defunct drive automatically when all of the following conditions exist:

The physical drive that failed is part of a RAID level-1 or RAID level-5 logical drive.
A hot-spare or standby hot-spare drive with a capacity equal to or greater than the capacity of the defunct drive is available the moment the drive fails.
- When multiple hot-spare drives are available, the ServeRAID adapter/controller searches for a hot-spare drive of the appropriate size. The smallest drive that meets this requirement enters the Rebuild state.
- If no hot-spare or standby hot-spare drives are available, the rebuild operation will start the moment you replace the defective drive.
  Note: If you physically replace the drive and the new drive does not appear in the Physical Drives branch of the Main Tree, you must scan for new or removed Ready drives.
No rebuild, synchronization, or logical-drive migration operation is in process.
