The prerequisites for creating Solaris Volume Manager elements are as follows:
Create initial state database replicas. If you have not done so, see Creating State Database Replicas.
Identify slices that are available for use by Solaris Volume Manager. If necessary, use the format command, the fmthard command, or the Solaris Management Console to repartition existing disks.
Make sure you have root privilege.
Have a current backup of all data.
If you are using the graphical user interface, start the Solaris Management Console and maneuver through it to get to the Solaris Volume Manager feature. For information, see How to Access the Solaris Volume Manager Graphical User Interface.
