Veritas File System 5.1 SP1 Administrator"s Guide (5900-1499, April 2011)

Note: Do not mount a multi-volume system with the ioerror=disable or
ioerror=wdisable mount options if the volumes have different availability
properties. Symantec recommends the ioerror=mdisable mount option both for
cluster mounts and for local mounts.
About volume sets
Veritas Volume Manager exports a data object called a volume set. A volume set
is a container for one or more volumes, each of which can have its own geometry.
Unlike the traditional Volume Manager volume, which can be used for raw I/O
access or to contain a file system, a volume set can only be used to contain a VxFS
file system.
The Volume Manager vxvset command is used to create and manage volume sets.
Volume sets cannot be empty. When the last entry is removed, so is the volume
set.
Creating and managing volume sets
The following command examples show how to create and manage volume sets.
See the Veritas Volume Manager Administrator's Guide, vxassist(1M) manual
page, and vxvset(1M) manual page.
To create and manage volume sets
1
Create a new volume set from vol1:
# vxassist -g dg1 make vol1 10m
# vxvset -g dg1 make myvset vol1
2
Create two new volumes and add them to the volume set:
# vxassist -g dg1 make vol2 50m
# vxassist -g dg1 make vol3 50m
# vxvset -g dg1 addvol myvset vol2
# vxvset -g dg1 addvol myvset vol3
