I compiled it, and it's working good. The only thing is, when I query the priority of a drive, I'm getting "Auto-volume Transfer not enabled": --- # ./mpath_prio_tpc /dev/sdc Auto-volume Transfer not enabled6 # ./mpath_prio_tpc /dev/sdd Auto-volume Transfer not enabled1 --- I seem to be getting 6 for my preferred path and 1 for standby, which is good. Is AVT required, or can I still use mpath_prio_tcp? I have multiple nodes of a Linux Cluster accessing the LUNs, so AVT has to be disabled.
