# BIG BROTHER - EXTERNAL SCRIPT FOR EMC POWERPATH
# David Levin - Intel MCD IS
# Version 1.0
# October 22 2001
#

#
# This external script will check the status of Powerpath devices.
# Reports red if device not operating.
# Reports clear if tool is not found to run test.
#

#
# SCRIPTS IN THE BBHOME/ext DIRECTORY ARE ONLY RUN IF 
# LISTED IN THE BBEXT VARIABLE OF $BBHOME/runbb.sh
# THIS IS FOR SECURITY.
#

#
# TEST NAME: THIS WILL BECOME A COLUMN ON THE DISPLAY
# IT SHOULD BE AS SHORT AS POSSIBLE TO SAVE SPACE...
# NOTE YOU CAN ALSO CREATE A HELP FILE FOR YOUR TEST
# WHICH SHOULD BE PUT IN www/help/$TEST.html.  IT WILL
# BE LINKED INTO THE DISPLAY AUTOMATICALLY.
#
TEST="emc"

# 
# BBPROG SHOULD JUST CONTAIN THE NAME OF THIS FILE
# USEFUL WHEN YOU GET ENVIRONMENT DUMPS TO LOCATE 
# THE OFFENDING SCRIPT...
#

#
# NOW SET SITE SPECIFIC VARIABLES
# THE PATH WHERE THE POWERPATH EXECUTABLE IS LOCATED
# NOTE: THIS PROGRAM CAN ONLY BE RUN BY ROOT.
# sudo UTILITY IS REQUIRED TO RUN THE POWERPATH BINARY
# Make sure you have configured the BB user in sudo for both commands
