Table 15. Add RAID 0 configuration input options (continued)
Option Value range Description
size
Maximum size based on the physical drives and
RAID level.
Sets the size of each virtual drive. The default
value is for the capacity of all referenced disks.
name
15 characters of length. Specifies the drive name for each virtual drive.
drives
Valid enclosure number and valid slot numbers for
the enclosure.
In e:s|e:s-x|e:s-x,y:
● e specifies the enclosure target.
● s represents the disk slot number.
● e:s-x is the range of disk slot numbers.
● e:s-x,y is the range of disk slot numbers
plus the disk with a slot number out of the
specified range.
If you replace s-x with 0-9, it will provide 10
RAID 0 virtual disks with each using one disk.
pdperarray
0 to 15. Specifies the number of physical drives per array.
The default value is automatically chosen.
sed
— Creates security-enabled drives.
pdcache on|off|default
Enables or disables PD cache.
pi
— Enables protection information.
dimmerswitch
default: Logical device uses controller default
power-saving policy.
automatic (auto): Logical device power
savings are managed by firmware.
none: No power-saving policy.
maximum (max): Logical device uses maximum
power savings.
MaximumWithoutCaching (maxnocache):
Logical device does not cache write to maximize
power savings.
Specifies the power-saving policy. Sets to default

wt|wb
wt: Write through.
wb: Write back.
Enables write through. Write back is the default.
nora|ra
ra: Read ahead.

strip 8, 16, 32, 64, 128, 256, 512, 1024
Sets the strip size for the RAID configuration.
aftervd

the specified VD.
spares
Number of spare physical drives present. Specifies the physical drives that are to be
assigned to a disk group for spares.
force
— Forces the addition of a security-capable physical
drive to a drive group without security.
Input example:
perccli /c0 add vd type=raid10 size=2gb,3gb,4gb names=tmp1,tmp2,tmp3 drives=252:2-3,5,7
