# #
|
|
#-------------------------------------------------------------------------#
|
|
# This xCAT script will use xdsh to get the Guids from Linux nodes #
|
|
# and AIX nodes, and save the results to file /opt/xcat/samples/ib/ #
|
|
# Guids.xcat, log file is /var/log/xcat/getGuids.log. #
|
|
# Command Syntax: #
|
|
# getGuids [-h] [-f output_file] #
|
|
# -f output_file #
|
|
# Specifies a file full path name that is used to save the #
|
|
# GUIDs output. #
|
|
# -h #
|
|
# Display usage information. #
|
|
# Exit codes: #
|
