Veritas Volume Manager 5.0.1 Administrator's Guide, HP-UX 11i v3, First Edition, November 2009

By default, the attribute stripe-mirror-col-split-trigger-pt is set to one gigabyte.
The value can be set in /etc/default/vxassist. If there is a reason to implement
a particular layout, you can specify layout=mirror-concat or layout=concat-mirror
to implement the desired layout.
To create a new mirrored volume, use the following command:
# vxassist [-b] [-g diskgroup] make volume length \
layout=mirror [nmirror=number] [init=active]
Specify the -b option if you want to make the volume immediately available for
use.
See “Initializing and starting a volume” on page 303.
For example, to create the mirrored volume, volmir, in the disk group, mydg, use
the following command:
# vxassist -b -g mydg make volmir 5g layout=mirror
To create a volume with 3 instead of the default of 2 mirrors, modify the command
to read:
# vxassist -b -g mydg make volmir 5g layout=mirror nmirror=3
Creating a mirrored-concatenated volume
Note: You need a full license to use this feature.
A mirrored-concatenated volume mirrors several concatenated plexes. To create
a concatenated-mirror volume, use the following command:
# vxassist [-b] [-g diskgroup] make volume length \
layout=mirror-concat [nmirror=number]
Specify the -b option if you want to make the volume immediately available for
use.
See “Initializing and starting a volume” on page 303.
Alternatively, first create a concatenated volume, and then mirror it.
See “Adding a mirror to a volume ” on page 315.
