Assigning Hot Spares - Adaptec 750i User Manual

Assigning Hot Spares

To assign a drive as a hot spare, click Make Hotspare in the drive's
Device Information window. Click Remove Hotspare to reassign an
existing hot spare drive as a normal drive.
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 0/1 and RAID 5 or 0/5 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.
