Use the following procedures to configure Veritas Volume Manager. If you have installed and configured VxVM using the product installer, you do not need to complete the procedures in this section.

For information on setting up VxVM disk groups and volumes after installation, see "Configuring Veritas Volume Manager" in the Veritas Storage Foundation Administrator's Guide.

In releases of VxVM (Volume Manager) before 4.0, a system that was installed with VxVM was configured with a default disk group, rootdg. The rootdg disk group had to contain at least one disk. By default, operations were directed to the rootdg disk group. From release 4.0 onward, VxVM can function without any disk group having been configured.
