Volume Group Definition Syntax

This appendix describes the syntax of a volumegroup definition that may be used as input to the

vxvoladm command. 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 {

[diskgroup "dgname"]

[excl on|off|true|false|yes|no]

[fmr on|off|true|false|yes|no]

[fstype type]

[group "group"]
