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 Volume Manager Administrator's Guide.

To carry out further tasks such as disk encapsulation or initialization, please see the Veritas Volume Manager Administrator's Guide.

In releases of VxVM (Volume Manager) prior to 4.0, a system installed with VxVM was configured with a default disk group, rootdg, that 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. Only when the first disk is placed under control must a disk group be configured. There is no longer a requirement that you name any disk group rootdg, and any disk group that is named rootdg has no special properties by having this name. During the setup procedures, you will be asked if you want to create a default disk group, and asked to specify its name.
