Veritas Volume Manager 5.1 SP1 Administrator"s Guide (5900-1506, April 2011)

See “Initializing and starting a volume” on page 326.
For example, to create the 10-gigabyte striped volume volzebra, in the disk group,
mydg, use the following command:
# vxassist -b -g mydg 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, mydg03, mydg04, and mydg05, use the following
command:
# vxassist -b -g mydg make stripevol 30g layout=stripe \
mydg03 mydg04 mydg05
To change the number of columns or the stripe width, use the ncolumn and
stripeunit modifiers with vxassist. For example, the following command creates
a striped volume with 5 columns and a 32-kilobyte stripe size:
# vxassist -b -g mydg make stripevol 30g layout=stripe \
stripeunit=32k ncol=5
Creating a mirrored-stripe volume
A mirrored-stripe volume mirrors several striped data plexes. A mirrored-stripe
volume requires space to be available on at least as many disks in the disk group
as the number of mirrors multiplied by the number of columns in the volume.
To create a striped-mirror volume, use the following command:
# vxassist [-b] [-g diskgroup] make volume length \
layout=mirror-stripe [nmirror=number_of_mirrors] \
[ncol=number_of_columns] [stripewidth=size]
Specify the -b option if you want to make the volume immediately available for
use.
See “Initializing and starting a volume” on page 326.
Alternatively, first create a striped volume, and then mirror it. In this case, the
additional data plexes may be either striped or concatenated.
See “Adding a mirror to a volume ” on page 355.
