Hi,

The former script has been updated to perform a little more checking and 
following a recent "event", the reset option is now implimented in a 
more harsh fashion. Oh.. and Wellcome is now spelt correctly :-)

# NB hostlist is a list of the hosts that are
# being monitored and ilname are the ilo devices
# being used to bring the hosts up/down.
#
# This script is using ipmitools as the ilo cli
# has proven unreliable. The X4200's are IPMI 2.0
# compliant.

# For heartbeat 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)
