create vdisk
Description
Creates a linear disk group using the specified RAID level, disks, and spares. This command applies to linear
storage only.
All disks in the disk group must be the same type (enterprise SAS, for example).
NOTE: A disk group can contain a mix of 512-byte native sector size (512n) disks and 512-byte
emulated sector size (512e) disks. For consistent and predictable performance, do not mix
disks of different rotational speed or sector size types (512n, 512e).
For each RAID level, the minimum and maximum numbers of disks supported are:
• NRAID: 1
• RAID 0: 2–16
• RAID 1: 2
• RAID 3: 3–16
• RAID 5: 3–16
• RAID 6: 4–16
• RAID 10: 4–16
• RAID 50: 6–32
For best practices for creating disk groups, see the Administrator’s Guide.
When you create a linear disk group, the system creates a linear pool with the same name. A linear pool can
contain a single linear disk group.

Parameters
assigned-to a|b|auto
Optional. For a system operating in Active-Active ULP mode, this specifies the controller to own the disk
group. To let the system automatically load-balance vdisks between controllers, use auto or omit this
parameter. In Single Controller mode, this parameter is ignored; the system automatically load-balances
vdisks in anticipation of the insertion of a second controller in the future
chunk-size 64k|128k|256k|512k
Optional. The amount of contiguous data, in KB, that is written to a disk group member before moving to the
next member of the disk group. For RAID 50, this option sets the chunk size of each RAID-5 subgroup. The
chunk size of the RAID-50 disk group is calculated as: configured-chunk-sizex (subgroup-members- 1). For
NRAID and RAID 1, chunk-size has no meaning and is therefore not applicable. The default size is 512k.
disks disks
The IDs of the disks to include in the disk group. RAID 10 requires a minimum of two RAID-1 subgroups each
having two disks. RAID 50 requires a minimum of two RAID-5 subgroups each having three disks. For disk
syntax, see Command syntax on page 17.
