===================================================================================
Create a new logical device
Options: Additional creation specifiers.
Stripesize <STRIPE>: Optional parameter for specifying a stripe size.
STRIPE is specified in kilobytes.
16, 32, 64, 128*, 256, 512 and 1024 are supported.
Legs <LEG>: Optional parameter for specifying number of sub-logical devices.
LEG is the number of sub-logical devices for RAID level 50 or 60. Default value is 2.
Name <NAME>: Optional parameter for specifying the name of the logical
device.
Some controllers do not support this parameter.
Method <METHOD>: Initialization method for the logical device.
Valid options include: BUILD and DEFAULT.
Wcache <WCACHE>: Write Cache setting for the logical device. Applicable only with maxCache creation.
Valid options are: WT, WB
WT: write-through (Disabled)
WB: write-back (Enabled)
LDcache <LDCACHE>: Cache setting for the logical device.
Valid options are: LON and LOFF
SSDOverProvisioningOptimization <enable | disable>: Specifies to initialize solid state drives that
support rapid parity initialization feature.
CacheLineSize <CACHELINESIZE>: Specifies the cache line size(KB) for maxCache.
Adjusting cache line size can impact maxCache performance and
maximum size supported. Larger cache line size can support larger
maxCache size. Default value for this parameter is 64.
Valid options can be 64, 128 and 256 based on controller support..
DataLD <LogicalDrive#>: Specifies the existing data logical device number to associate
with the newly created cache logical device.
Size: Size of the logical device in megabytes.
Use MAX to set size to all remaining available space.
Use MAXMBR to set the size to 2TB.
Raid#: Raid level for the new logical device.
0, 1, 1ADM, 10, 10ADM, 5, 6, 50 and 60 are supported.
Channel# ID#: A list of space-delimited channel number and
device number pairs for each device to add
to the logical device.
ARRAY <Array#>: The Array number on which the logical device needs to be created.
RAIDZEROARRAY: Create arrays from list of physical device(s) specified.
Each array will contain exactly one physical device and one RAID 0 logical device.
Default values will be applied for all logical device(s) created.
ALL: Create arrays form list of physical device(s) connected to controller.
noprompt: Don't prompt for confirmation.
* default parameter in MOST circumstances
