[storsave=<protect|balance|perform>] 
This command allows you to create a new unit on the specified controller. You 
specify typedisks, and optional stripe size. By default the host operating 
system will be informed of the new block device, write cache will be enabled, 
and a storsave policy of protect will be set. 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 
(7000/8000 only). 
Example: 
type=raid5
When a new unit is created, it is automatically assigned a unique serial 
number. In addition, users can assign the unit a name.
                                      
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. 
                                      
 
Note:
 The unit’s serial number cannot be changed.
