After you decide on a volume layout, you can use the vxassist command to create
the volume.
Before creating a volume, make sure the following conditions are met:
■ Creating a volume requires a disk group name, volume name,
volume size, and volume layout. You will also need to know subdisk
names if you are creating a striped volume.
■ Striped or mirrored volumes require at least two disks.
■ Striped pro and concatenated pro volumes are mirrored by default,
so a striped pro volume requires more disks than an unmirrored
striped volume and a concatenated pro volume requires more disks
than an unmirrored concatenated volume.
■ You cannot use a striped pro or concatenated pro volume for a
root or swap volume.
■ A RAID-5 volume requires at least three disks. If RAID-5 logging
is enabled, a RAID-5 volume requires at least four disks.
RAID-5 mirroring is not supported.

The following is an example of creating a volume using the vxassist
command:
To create a 1 GB mirrored volume called db01 on the PRODdg disk group:
# /opt/VRTS/bin/vxassist -g PRODdg make db01 1g PRODdg01
Creating a volume set
Volume Sets enable the use of the Multi-Volume Support feature with Veritas File
System (VxFS). It is also possible to use the Veritas Enterprise Administrator
(VEA) to create and administer volumes sets. For more information, see the VEA
online help.
Before creating a volume set, make sure the following conditions are met:
