– k—Species the size in kilobytes
– m—Species the size in megabytes

– t—Species the size in terabytes
• -sc—Number of spans in a virtual disk (required for multi-span
RAID level).
NOTE
:
– For PERC9, if the value of
controller.SupportRAID10UnevenSpans is
supported, you can enter only 0 for this option
while creating RAID level 10. The created RAID10
virtual disk displays the spandepth as
1 (default).
– For other controllers:
◦ The default value for multi-span RAID levels is 2
and for basic RAID level is 1.
◦ For hybrid RAID levels such as RAID10, RAID50,
and RAID60, this option is mandatory.
