How do I remove a dedicated (DHS) or global hot spare (GHS)?

Question

I want to replace a hot spare with a new disk, for example to replace a smaller disk with a bigger one or when the manufacturer does a callback of a series of disks.

How do I do that?

Answer 1

Determine enclosure and slot with this command:

storcli /c0/eall/sall show

That should print something like this:

--------------------------------------------------------------------------------
EID:Slt DID State DG     Size Intf Med SED PI SeSz Model                Sp Type 
--------------------------------------------------------------------------------
...
252:4    12 GHS    - 2.728 TB SATA HDD N   N  512B XXXXXXXXXXXXXXXXXXXX U  -    
...
--------------------------------------------------------------------------------

To remove the disk, you first have to turn it into a "unconfigured good" disk by deleting the hotspare status:

storcli /c0/e252/s4 delete hotsparedrive

The drive will now look like this:

252:4    12 UGood  ...
            ^^^^^

Now you can turn it off using

storcli /c0/e252/s4 set offline

which changes the state to:

252:4    12 UGood  - 2.728 TB SATA HDD N   N  512B XXXXXXXXXXXXXXXXXXXX D  -    
                                                                        ^

(the value in the "Sp" = Spun column changed from "U" = Up to "D" = Down).
