44 Alphabetical list of commands

create vdisk

Description Creates a vdisk using the specified RAID level, disks, and spares. All disks used in a vdisk and its

spares must be either SAS or SATA; mixing disk types is not supported.

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

Syntax

create vdisk level nraid|raid0|r0|raid1|r1|raid3|r3|raid5|r5|raid6|r6|raid10

16k|32k|64k] [mode online|offline] name

Parameters level nraid|raid0|r0|raid1|r1|raid3|r3|raid5|r5|raid6|r6|raid10|r10

|raid50|r50

Specifies the RAID level.

disks disks

IDs of the disks to include in the vdisk. RAID 10 requires a minimum of two RAID-1 sub-vdisks each

having two disks. RAID 50 requires a minimum of two RAID-5 sub-vdisks each having three disks.

For syntax, see Command syntax.

assigned-to a|b|auto

Optional. The controller to own the vdisk. To have the system automatically load-balance vdisks

between controllers, use auto or omit this parameter.

spare disks

Optional. IDs of 1–4 dedicated spares to assign to a RAID 1, 3, 5, 6, 10, or 50 vdisk. For syntax,

see Command syntax.

chunk-size 16k|32k|64k

Optional. The amount of contiguous data, in KB, that is written to a vdisk member before moving to

the next member of the vdisk. The default is 64k.

mode online|offline

Optional. Specifies whether the vdisk is initialized online or offline.

• online: Enables you to use the vdisk immediately after creating it while it is initializing.

Because online uses the verify method to create the vdisk, it takes longer to complete initializing

than offline. Online initialization is fault tolerant. This option is the default.

• offline: You must wait for the vdisk initialization process to finish before using the vdisk;

however, offline takes less time to complete initializing than online. At the time of creation, a

vdisk using offline initialization can have either one volume or none. If you want the vdisk to have

more than one volume, create the vdisk with no volumes and then add volumes after initialization

is complete.

name

A name for the new vdisk. The name is case sensitive, cannot include a comma, double quote, or

backslash, and can have a maximum of 17 bytes. A name that includes a space must be enclosed in

double quotes.

Example Create the RAID-1 vdisk VD1 using two disks in the first enclosure:

# create vdisk level raid1 disks 1.1,1.3 VD1

Success: Vdisk created.

Create the RAID-50 vdisk VD2 having three RAID-5 sub-vdisks, each having three disks:

# create vdisk level r50 disks 1.1-3:1.4-6:1.7-9 VD2

Success: Vdisk created.
