However, you can try following 1) I would suggest you to set the filter setting in lvm.conf to properly scan your mpath* devices and local disks. 2) Enable blacklist section in multipath.conf eg: blacklist { devnode "^(ram|raw|loop|fd|md|dm-|sr|scd|st)[0-9]*" devnode "^hd[a-z]" } # multipath -v2 Observe the box. Check whether that helps ...

I have seen it turning the blade off by default. Through fence_bladecenter --missing-as-off...... -o off returns me a correct result when run from command line but fencing fails through "fenced". I am using RHEL 5.5 ES and fence_bladecenter version reports following - fence_bladecenter -V 2.0.115 (built Tue Dec 22 10:05:55 EST 2009) Copyright (C) Red Hat, Inc. 2004 All rights reserved.
