Veritas File System 5.0 AdministratorÆs Guide, HP-UX 11i v3, First Edition, May 2008

■ Using the vxdump command.
Volume availability is supported only on a file system with disk layout Version 7
or later.
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 for cluster
mounts and ioerror=mwdisable for local mounts.
About volume sets
Veritas Volume Manager exports a data object called a volume set. Unlike the
traditional Volume Manager volume, which can be used for raw I/O access or to
contain a file system, a volume set is a container for multiple different volumes.
Each volume can have its own geometry.
The Volume Manager vxvset command is used to create and manage volume sets.
Volume sets cannot be empty. When the last entry is removed, the volume set
itself is removed.
Creating and managing volume sets
The following command examples show how to create and manage volume sets.
To create and manage volume sets
1
Create a new volume set from vol1:
# vxassist make vol1 10m
# vxvset make myvset vol1
2
Create two new volumes and add them to the volume set:
# vxassist make vol2 50m
# vxassist make vol3 50m
# vxvset addvol myvset vol2
# vxvset addvol myvset vol3
