I am having a back and forth with RH support on this.
Problem is my fibre attached qdisk is dm-multipathed yet when I issue "mkqdisk -L" I don't see the /dev/mapper/mpath... but LUNs seen from individual fibre paths.
In addition when I unplug cable (path B) for /dev/sdh1 (same as /dev/dm-13), that node gets fenced out.
# mkqdisk -L
mkqdisk v0.5.2

Has anybody got dm-multipath working for qdisk on RHEL 4.8 cluster?
