2 # Script to create device nodes for SMART array controllers
3 # Usage:
4 # mkdev.ida [num controllers] [num log volumes] [num partitions]
5 #
6 # With no arguments, the script assumes 1 controller, 16 logical volumes,
7 # and 16 partitions/volume, which is adequate for most configurations.
8 #
9 # If you had 5 controllers and were planning on no more than 4 logical volumes
10 # each, using a maximum of 8 partitions per volume, you could say:
11 #
12 # mkdev.ida 5 4 8
13 #
14 # Of course, this has no real benefit over "mkdev.ida 5" except that it
15 # doesn't create so many device nodes in /dev/ida.
