# This script gets or sets the power management policy for
# one or more systems.  A time schedule can be setup in
# CRON to select a policy and time period for the policy to
# be in effect. This script can also be ran manually.

# The system IP(s) or hostname(s) for the Service Processor(s) of the
# host system(s) is populated in the default file /tmp/spips, which
# be changed on the command line.
