Greetings,

I would appreciate support correcting another issues. We have two scst 
storage arrays configured  with drbd replication and alua settings via 
targets. When we run sg_inq and sg_rtpg we see the preferred port. 
Multipath however doesn't seem to respect the priority path. We then 
tried setting active and nonoptimized on the two storage arrays without 
success. If I'm reading this correctly the devices are reporting their 
state to the multipath system however it's not respecting the values. 
I'd appreciate any assistance on the matter. Pastebin all the 
appropriate .conf and command outs.

Thanks

Ross Anderson
