Review comment:
       Hi @shwstppr, I talked with my team about this behavior. First, your 
controller ids are correct. Increments are per controller type. For this reason 
is my implementation not better as the old one. Perhaps we could check in the 
sort algorithm if device type == scsi controller, but then it isn't no longer 
possible to boot from other controller types. It exist no safety way to find 
out which disk is bootable. The only way to get sure that  CS use the right 
volume is that the user indicates during the ingest process via rest call which 
volume is the right. Therefore I think we should close this pull request. What 
do you think?
