# Shell script to add new disks for SCO UNIX
# NOTE:
# 1. drivenum is for each controller, e.g drive 2 controller 1
#    while disknum is for the system. 
# 2. About disknum, it is set as the next available integer in
#    the system.
#    That is, disknum is determined by the order you mkdev your disk.
#    E.g there has already been one ST506 controller with one drive,
#	 now, if we install a new PTI controller as a secondary card,
# 	 with only one drive as the card's 3rd drive. 
#        Then this new drive's:
#		drivenum = 3
#		ctrlnum  = 1
#	        disknum = 1 (after 0).
# 3. The variable, "minor_seed" is determined only by drivenum.
