There is a HS22 Blade with RAID. I removed one of the mirrored disk, and used it for other, but now I'm inserting it back, but it doesn't sync from the working disk.
cfggen shows the following:

if I got it you detached 1 disk from a RAID1, then it was switched on in an other server and eventually introduced back into the original server: if so the controller could be confused on which is the primary disk that have to mirrored on the other.
can you initialize again the disk that's supposed to receive the data ? this will erase the RAID information from that disk.
