[writepolicy=<wb| wt| wc| nwc>] Parameter (Optional)
Different controllers support different write policies. Table 8-10 indicates
how to specify the [writepolicy=<wb| wt| wc| nwc | fwb>] parameter for
each of the write policies.
[name=<string>] Parameter (Optional)
Use this parameter to specify a name for the virtual disk. For example:
name=VirtualDisk1
[spanlength=<n>] Parameter (Required for RAID 50 and RAID 60 and optional for
RAID 10)
Use this parameter to specify the number of physical disks in each stripe. This
parameter applies only to RAID-50 virtual disks. If you are not creating a
RAID-50 virtual disk, do not specify this parameter. For example:
spanlength=3
For RAID 10 on SAS controllers with firmware version 6.1 and later,
spanlength is optional. Also, you can now specify the spanlength as an
even number with a maximum of 8 spans with 32 physical disks each. For
example,
omconfig storage controller action=createvdisk
controller=1 raid=r10 size=min pdisk=
1:1:0,1:1:1,1:1:3,1:1:4,1:1:6,1:1:7,1:1:8,1:1:9
spanlength=4
