You should reboot your operating system to ensure that the hot
spare drive is recognized correctly.
Hot spares are reserved to automatically replace failed drives in
RAID 1 or 10 and RAID 5 or 50 arrays and cannot be accessed by
the operating system for data storage. Hot spares can only protect
drives of equal or less capacity that are attached to the same
controller as the hot spare.
When a drive failure occurs in an array protected by a hot spare,
the controller automatically starts rebuilding data onto the hot
spare. During this process, Storage Manager swaps the positions of
the failed drive and the hot spare in the Logical Configuration
View. The failed drive appears with a red failed flag in the former
position of the hot spare, and the hot spare appears as a member of
the array group with a white flag indicating that a rebuild
operation is in process. The array and LSU icons appear with
yellow (degraded) flags.
When the rebuild is complete, the hot spare icon and flags
disappear and the drive is displayed as a normal member of the
array. The red flag remains on the failed drive until that drive is
replaced or returned to Optimal status.
To replace the failed drive, follow these steps:
1 Follow the steps in your hardware documentation to remove
and replace the failed drive.
2 Click Make Optimal in the new drive's Information window.
The new drive becomes the hot spare, replacing the previous
hot spare that is now a member of the rebuilt array group.
Note: If you want to try using the drive again, select Make
Optimal without removing the drive. If the operation fails,
you should replace the drive.
Running a Verify Process
Running a manual Verify for a RAID array ensures that the
redundant information contained in the array is consistent.
