This guide tells how to install, configure, and manage Enterprise Volume Management System (EVMS). EVMS is a storage management program that provides a single framework for managing and administering your system's storage.

This guide is intended for Linux system administrators and users who are responsible for setting up and maintaining EVMS.

For additional information about EVMS or to ask questions specific to your distribution, refer to the EVMS mailing lists. You can view the list archives or subscribe to the lists from the EVMS Project web site.

The following table shows how this guide is organized:
