By now or within the next couple of hours the sparing in will have finished and you 'll be able to see the two spare drives.
If this does not happen, you have to tell us more about your storage system.

"sparing out" is the process by which a failed drive is replaced by the spare in a RAID group. In this process the spare drive is built from the remaining drive(s) of the RAID group. This is what happened when your drive failed.
"sparing in" is the process by which the spare drive is copied (not rebuilt) back to the replaced drive. This is what is happening right now in your storage system. If you look at the spare and the replaced drives, their activity lights are blinking nonstop.

Re: Raid 5 setup with 2 spares - how do I .....
The spare drives section is cut-off in the screenshot but I assume that disk 4 is the only one showing in there.
I don't have access to an ACU right now and can not provide anymore details.
Two other questions.
How long has it been in hours when drive 0 failed? When drive 5 was incorporated in the logical drive, the rebuilding of drive 5 can take hours and sometimes days. Until drive 5 is completely rebuilt, the replaced drive will not be used.

Re: Raid 5 setup with 2 spares - how do I .....
Drives 0,1,2,3,5 are all data drives in a RAID-5 array group, the array-A. Array-A has 104GB in logical drive 1 and 43GB unused. The used and unused space is spread out on all 5 drives. Usually you can NOT take any drives out of an array without rebuilding it. This would be a function of the array controller.
Also depending on your array controller, what you can do is expand logical disk 1 to use the remaining unused space. But don't do it before you check if your OS can see the increase in the size of the LUN as a drive partition increase.
