 s represents the slot in the enclosure.
e:s-x- is the range convention used to

represent slots s to x in the enclosure e (250
characters max.).

physical drive) is used in each [e:s] pair. As an
example, if you use 4096 bytes in the e0:s0 pair, use
4096 bytes in the e1:s1 pair too. Mixing of block
sizes between the [e:s] pairs is not supported.
Specifies the number of physical drives per array.
The default value is automatically chosen.
