# The X4200's are IPMI 2.0 compliant and this script may therefore 
# also work on other ipmi compliant ILO hardware although your 
# mileage may vary. To use this you will require impitools installed
# on your servers. 

# Hostlist is a list of the hosts that are being monitored and 
# iloname are the ilo devices being used to bring the hosts up/down.
# these are configured from within heartbeat.
#
# For heartbeat configuration we need:
#
# gethosts (hostlist defined), on (bring up ilo) off (bring down ilo),
# reset (reset ilo), status (are host, ilo and ilo functionaility 
# alive ?!) getconfignames (required script parameters),  getinfo-foo
# (generic info, limited use)

# Source ocf code status.
. /usr/lib/heartbeat/ocf-shellfuncs

# IPMI communication variables
IPMITOOL="/usr/bin/ipmitool"
