# Description
#  Wrapper script to the HA software.  This script places a node
#  resources into managed mode.
#
#  The resources ...
#    resources...._drbd
#    resources...._fs  
#  are not included in this.
#
#  To perform maintenance on these please stop heartbeat.
#
# Parameters
#           -f:  Forces unmanaged status when quorum is not achieved
#         None:  Places all resource (with the above exceptions) into
#                managed mode
#  resource[s]:  specified resources only
