/usr/sbin/ldev - list devices, determine validity, etc.
/usr/sbin/lhbadm - wrapper for heartbeat utils for failover/failback/status
/etc/ha.d/resource.d/Lustre - heartbeat resource agent (wraps init script)
/etc/init.d/lustre - lustre init script
/etc/init.d/lnet - lnet init script
/usr/sbin/haconfig - helper script for building heartbeat config files

The scripts use two configuration files:
 /etc/ldev.conf - maps hostnames to failover partners, devices, and labels
 /etc/nids - hostnames to lustre NIDS

In addition to heartbeat support, the ldev script enables parallel
execution of commands against all luns configured on a server.  The
lustre init script supports devices backed by Linux software RAID, ZFS,
or traditional block devices.

NOTE: these scripts presume the udev rules for persistent block device
naming are in place, in particular that lustre labels can be mapped to
block devices in /dev/disk/by-id.
