Summary
The config command has two options: Automatic and Express.
Automatic configuration takes all available unconfigured physical drives to create
an optimized disk array following a default set of parameters. There are no
options.
Express configuration takes your input, creates one or two arrays, and spreads
their capacity evenly over all of the logical drives that you specify.
The redundancy option creates redundant logical drives (RAID 1, 10, 1E, 5, 50,
6, or 60).
The capacity option enables optimizes the logical drives for capacity.
The performance option optimizes the logical drives for performance.
If you choose all three options, redundancy gets highest priority and capacity
gets lowest priority.
