HP-UX LVM Supported Limits (September 2008)

Abstract
Starting with HP-UX 11i v2 (11.23), the supported limits of LVM volume groups has gradually increased.
In HP-UX 11i v3 (11 .31), LVM delivers significant performance, scalability, usability, and availability
enhancements. After the initial release of HP-UX 11iv3 in February 2007, three updates occurred in
September 2007, March 2008, and September 2008. This white paper summarizes the LVM supported
limits for different volume group versions supported on HP-UX releases.
This document is intended for system administrators, operators, and customers who are creating or
managing volume groups. You must also have a basic knowledge of LVM.
Introduction

versions of volume groups:
• Version 2.1 volume group (supported on 11iv3 September 2008 update and later)
• Version 2.0 volume group (supported on 11iv3 March 2008 update and later)
• Version 1.0 volume group (legacy volume group version, supported on all HP-UX releases and
updates
This paper is structured into two parts: the original Version1.0 volume group and the Version2.0 and 2.1
volume groups. For information about the differences and how to use Version 2.x volume groups, see the
