Hot spare rebuilt
Hi All, I am looking for a procedure to rebuilt a hot spare disk. For some apparent reason our hot spare disks are full but there is no fault with any disks in the array.

A normal hot spare will have a single bound LUN which consumes the entire disk. That LUN is where the data is copied to when a disk failure occurs. As long as the Disk is in a 1-disk Hot Spare RAID Group, and has a Hot Spare type LUN bound, it should work fine.

it should start rebuilding on its own as long as you have correct capacity disks defined as hot spares.

It is not rebuilding (there is no disk failure), therefore i like to force rebuilt.
Capacity is correct.

when you say hot spares are full, you mean they are in use or they are listed as "Inactive" ?

That sort of answered my questions thanks Richard, is that why the hot spare disks have no free space left i.e used 100% of the total capacity. Is there a way to test hot spare making sure they will work if there is a disk failure

Yes, as mentioned previously they have data and the disks are full to 100%. what will happen if there is a disk failure and the hot spare kick-in. It probably will fail as there is no free space left in the hot spare disks.

because the hot spares are currently full but there is no faults with any disks. I need to get this done so if we have a disk failure then we have hot spare ready for action.

ok so you have hot spares listed as Inactive, meaning they are ready to kick-in whenever you experience drive failure.

you can try proactive hot sparing, although it copies data to HS not rebuilds it.

Here is the correct answer:
Hot Spares are owned by the system. Free space is not available on Hot spares unless it is invoked for a failed drive.
Thanks all
