Creating a Striped Volume

NOTE You may need an additional license to use this feature.

A striped volume contains at least one plex that consists of two or more

subdisks located on two or more physical disks. For more information on

striping, see “Striping (RAID-0)” on page 21.

NOTE A striped volume requires space to be available on at least as many disks

in the disk group as the number of columns in the volume.

To create a striped volume, use the following command:

# vxassist [-b] [-g diskgroup] make volume length

layout=stripe

NOTE Specify the -b option if you want to make the volume immediately

available for use. See “Initializing and Starting a Volume” on page 244

for details.

For example, to create the 10-gigabyte striped volume volzebra, use the

following command:

# vxassist -b make volzebra 10g layout=stripe

This creates a striped volume with the default stripe unit size (64

kilobytes) and the default number of stripes (2).

You can specify the disks on which the volumes are to be created by

including the disk names on the command line. For example, to create a

30-gigabyte striped volume on three speciﬁc disks, disk03, disk04, and

disk05, use the following command:

# vxassist -b make stripevol 30g layout=stripe disk03 disk04

disk05
