Thanks Tore . I plan to add mpath_prio_alua_pillar to the code base to return different priorities for iSCSI and FC paths for combination luns .

Make a small wrapper script that invokes mpath_prio_alua and also checks if the path is to a iSCSI volume or not (you can probably determine this by looking somewhere beneath /sys/block/$dev/). If it is, add 100 to whatever mpath_prio_alua returned, and print the sum. Regards -- Tore Anderson -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
