# EvmsSCC
# Description: Runs evms_activate in a heartbeat cluster to activate a
# EVMS shared cluster container in the cluster.
# Original Author: Jo De Baer (jdebaer@novell.com)
# Original Release: 06 Nov 2006
#
# usage: ./EvmsSCC {start|stop|status|monitor|meta-data}
#
# The goal of this resource agent is to provoke the creation of device file
# in /dev/emvs which correspond to EVMS2 volumes that reside in a EVMS2 shared
# cluster container. As such it should be run as a clone resource in the
# cluster. Logic inside the resource agent will make sure that "evms_activate"
# is run on only one node in the cluster, both at cluster startup time as well
# as when a node joins the cluster.
#
# Typically, resources that need to mount EVMS2 volumes should run after this
# resource agent has finished it's run. As such those resources should be made
# "dependent" on this resource agent by the cluster administrator. An example
# of resources that should depend on this resource agent are Filesystem resource
# agent that mount OCFS2 volumes that reside on EVMS2 volumes in a shared
# EVMS2 cluster container.
#
# For this resource agent to do it's job correctly, evmsd must be running on
# the node where the agent is started. Usually evmsd is started by the cluster
# software via a respawn statement in /etc/ha.d/ha.cf. If you encounter timing
# issues where evmsd is not yet started but where the cluster already starts
# the EvmsSCC clone, then you should comment out the evmsd respawn statement
# in /etc/ha.d/ha.cf and start evmsd on each node in the cluster via a separate
# clone resource agent. The EvmsSCC resource agent cloneset should then be made
# dependent to this evmsd cloneset. This will guarantee that emvsd is running
# before EvmsSCC is started, on each node in the cluster.
