However, preferred_path is still not maintained as that that is relatedThere is an issue with the preferred path in general, namely that it overlays the ALUA states (ie you can have 'acive/non-optimized' _and_

multipath).
the preferred path bit set). So it only makes sense for explicit ALUA
as then the preferred path bit gives us an indicator that we might /
should switch paths.
If we restrict ourselves to implicit ALUA (which I'm advocating anyway
for scsi-multipath) the preferred path becomes rather pointless as
we cannot influence path selection at all.
ok, fine, I won't touch for native scsi multipath.
Thanks
