# v 0.1 First functional plugin deployed at NRAO
# v 0.1 Better error checking
#	Recognize a disk that's rebuilding as OK
# v 0.5 Run without arguments to check all arrays on
#	the controller
# v 0.6 Handle intances where the controller doesn't
#	show up as errors
#


# Change this if you have installed the openmanage server admin tools
# somewhere else or have not created the symlink
