"Feature-wise" - this seems familiar to the usage I've seen for the
"sgio='unfiltered'" setting for a 'lun'. That is the ability to allow
certain SCSI command through to the disk and in particular I recall it
being used for some sort of fencing operation, but the details escape my
memory right now. In order to use 'sgio' though you have to either have
device='lun' for disk type='block'/'network' or 'volume' (when using a
storage pool).
