[maint] createunit
[noscan] [gDsk_Grp] [nocache] [autoverify]
[ignoreECC]
This command allows you to create a unit on the specified controller cid, of
type rRAIDType, optional stripe size of kStripe, using one or many disks
specified by pid_list. By default the host operating system is informed of the
new block device and write cache is enabled. In case of RAID 50, you can
also specify the layout of the unit by specifying the number of disks per disk
group with the gDsk_Grp option.
cid is the controller name as in c0, c1, etc.
rRAIDType is the RAID or Logical Unit type as in RAID 0, RAID 1,
RAID 5, RAID 10, RAID 50, single, spare, and JBOD. The following table
illustrates supported types and controller models.

pid_list is a list of ports (disks) to be used in the construction of the specified
unit. One or more ports can be specified. Multiple ports can be specified using
a colon (:) to separate port indexes and a dash (-) to include a range of port
indexes. A dash indicates a range and can be mixed with colons. For example
p0:1:2-5:9:12 indicates port 0, 1, 2 through 5 (inclusive), 9 and 12.
kstripe indicates the stripe size to be used. The following table illustrates the
supported and applicability of stripes on unit types and controller models.
Stripe size units are in K (kilobytes).
