–t <RAID_type>
Specifies the RAID type of the logical disk: r0 for RAID-0, r1 for RAID-1, r5 for RAID-5, or
r6 for RAID-6. If no RAID type is specified, the default is r1.
–ssz <size_number_chunklet>
Specifies the set size in terms of chunklets. The default depends on the RAID type specified:
2 for RAID-1, 4 for RAID-5, and 8 for RAID-6.

specified, no row limit is imposed.
–ss <size_KB>
Specifies the step size from 32 KB to 512 KB. The step size should be a power of 2 and a
multiple of 32. If no value is entered, the step size defaults to 256 KB for RAID-0 and
RAID-1, and 128 KB for RAID-5. For RAID-6, the default is a function of the set size.

magazine (mag). This option has no meaning for RAID-0.

chunklets). If no argument is specified, the default characteristic is
