As part of parent tasks we're deploying raid controllers for hp machines in HBA mode, the icinga HP raid check would need some tweaking to consider this case too, its current output is in state UNKNOWN:
Cannot read line ' HBA Drives' gotten from hpssacli controller slot=0 pd all show
The icinga check has been fixed, we need to fix also get-raid-status-hpssacli (see also https://gerrit.wikimedia.org/r/c/407447/)
