#	This script builds a matrix file that describes disk devices.
#	Output is sent to standard out and is in the following form:
#		<symid><lunid> <device> <director,interface,lun> <size>
#
#	Notes: we use the last 3 digits of the Symmetrix ID to distinguish
#		between boxes.  If this causes a problem, change it.
