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