Appendix
D
Volume group definition
syntax
This appendix describes the syntax of a volumegroup definition that may be
used as input to the
vxassist and vxvoladm commands. Volume groups are
generally used to create several volumes at the same time within a storage pool
and are given equal weighting by Veritas Intelligent Storage Provisioning (ISP)
when allocating storage resources.
The syntax of a volumegroup definition is shown here:
volumegroup {
