This command allows you to create a new unit on the specified controller. You
specify
type
,
disks
, and optional
stripe
size. By default the host operating
system will be informed of the new block device and write cache will be
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
group
attribute.
/cx
is the controller name, for example /c0, /c1, and so forth.
type=RaidType
specifies the type of RAID unit to be created. Possible unit
types include
raid0
,
raid1
,
raid5
,
raid10
,
raid50
,
single
,
spare
, and
JBOD
.
Example:
type=raid50
When a new unit is created, it is automatically assigned a unique serial
number. In addition, users can assign the unit a name.
Note:
The unit’s serial number cannot be changed.
The following table shows supported types and controller models.
disk=p:-p
consists of a list of ports (disks) to be used in the construction of
the specified unit type. One or more ports can be specified. Multiple ports can
be specified using a colon (:) or a dash (-) as port index separators. A dash
indicates a range and can be mixed with colons. For example
disk=0:1:2-
5:9:12
indicates port 0, 1, 2 through 5 (inclusive), 9 and 12.
stripe=Stripe
consists of the stripe size to be used. The following table
illustrates the supported and applicable stripes on unit types and controller
models. Stripe size units are in K (kilobytes). If no stripe size is specified,
64K is used by default, if applicable. If you need to change the stripe size after
the unit is created, you can do so my migrating the unit.
