These parameters are described in the following paragraphs.
RAIDset-name
Assigns a name to the RAIDset. This is the name used with the ADD UNITS

The RAIDset-name can consist of a maximum of nine printable characters

members of the RAIDset. If more than one disk drive in the spareset is the
correct size, the controller selects a disk drive giving the best
performance.
■ Specify POLICY=BEST_PERFORMANCE to choose a replacement disk
drive from the spareset resulting in the best performance of the RAIDset.
