Re: hpacucli - can't add spare to RAID1
Drive 1:2 is reportet as 36,4 GB
Drive 1:3 is reportet as 36,7 GB
Your spare drive is reportet as 36,6 GB
So you hotspare is smaller than one of the drives in the array.
As far as I remember, there was an advisory on problems with the size reporting, and possibly a FW fix.
But why are you adding a hot spare now?
A hot spare, is a spare disk, that is idle. Actually it's powered off, while not in use. it is supposed to kick in when a disk in the array(s) fail, and will be active until you replace te failed drive. Once you replace the failed drive, data from the spare will be copied to the replacement disk, and the hotspare will become spare again.
Also if you want a spare disk, why not have a disk that has the same size as the largest disk on the array controller, and then use it as a global spare disk for all arrays?
What happens if you replace the failed disk, and insert the spare disk. Does it start rebuild, as it should do?
Take a look on the technology brief's, they are very good:

Re: hpacucli - can't add spare to RAID1
I replaced the drive manually to disk smaller size (36.6) and array start rebuilding. After the rebuild, I'll try again to add hot spare 36.6G

sever is unreacheble now, because the system partition was on the array :)

Re: hpacucli - can't add spare to RAID1
You have one chance, that might get you back.
Power off server.
Remove te new replacement drive.
Re-seat the failed drive (drive 1:2)
don't put a drive in 1:3
Power on-server.
Let it start in interim recovery mode (F2 when prompted by the array controller).
insert spare drive.
If re-seating drive 1:2 get it back on-line, it will restart rebuild, and if it stay up long enough your safe.

Re: hpacucli - can't add spare to RAID1
Same problem except with exact same size and model of drive. I'd like to put in a spare so it'll rebuild from the failed disk.
Perhaps the solution is to delete the failed disk from the array and add a different one but that's a bit risky for my taste.

Re: hpacucli - can't add spare to RAID1
Replaceing a failed disk is not rocket sience ;-)
If you got hotswap disks, simply pull out the failed disk.
wait 30 sec.
insert the new/spare disk.
Reconstruktion start automatically.
All done on-line.
If you got internal disks (not accessible without removing the top/side cover).
Then the server must be powered down.
disk replaced.
server powered up.
