VRM Maintenance Facility (VMF) Overview

A-4 AIX Operating System Problem Determination Guide
VMF is a standalone tool you can use to display and modify data
on direct access storage — both fixed disk and diskette. The
primary purpose of the tool is to help diagnose problems with the
fixed disk when the problem has made the system inoperable. You
can, however, also use VMF as a standalone tool to install VRM
software or its associated device drivers. VMF runs as a diskette
based, standalone, virtual machine. VMF is available on the VRM
install diskette as an option on the install menu. To use VMF,
select the Maintenance Facility on the Install menu and then enter
VMF commands on the command line.
