# Sample xCAT post script for configuring eth1 based on eth0 settings and
# some conventions.
# This scripts works for both diskfull installs, diskless boots on AIX or Linux.
# the nic is passed as the only argument. All other required attributes are
# passed in as environment variables. These are set in mypostscript.tmpl as follows:
# xCAT post script for configuring additional ethernet nics. Information is
# retreieved from nics table. Environment variables are set in the postscript
# The nic (i.e. eth1, en1) is passed as the only argument.
# Environment variables are set in the postscript in the mypostscript.tmpl
# file on the management node:
#
#
# NICNODE - the name of the node minus the NICHOSTNAMESUFFIXES
# NICIPS - the ip address for this nic
# NICHOSTNAMESUFFIXES - the suffix to combine with the NICNODE for the hostname
# NICTYPES - for configeth - this must be ethernet
# NICCUSTOMSCRIPTS - parsed in confignics to invoke this script if set. (not used here)
# NICNETWORKS - the network this nic is attached to. Must also verify this network is
# set in the networks table.
