Installation Requirements

This section describes the installation requirements for this release.

Required Hardware

LVM and MirrorDisk/UX have no hardware requirements beyond the requirements of the HP-UX 11i v3 operating system. Both products run on all supported HP 9000 and HP Integrity servers.

Required Software

Since LVM is installed with the HP-UX 11i v3 operating environment, there are no software requirements beyond the requirements of the HP-UX 11i v3 operating system. MirrorDisk/UX requires the BaseLVM™ product.

Required Patches

For each of the following subsystems, you can download patches from the following website:

http://www2.itrc.hp.com/service/patch/mainPage.do

Mass Storage Critical Resource Analysis

The Mass Storage Critical Resource Analysis (MS CRA) tool checks for a maximum of two mirror copies of a logical volume. However, Version 2.x volume groups allow up to five mirror copies. To enable MS CRA to check for a maximum of five mirror copies of a volume, you must install the following patch, or a superseding patch:

PHCO_37562

MS CRA checks for a maximum of 511 physical volumes in a volume group. However, Version 2.1 volume groups allow up to 2048 physical volumes. To enable MS CRA to check for a maximum of 2048 physical volumes in a volume group, you must install the following patch:

PHCO_38145

PHCO_38145 supersedes PHCO_37562. Installing PHCO_38145 enables both checks.

mkfs and mkboot Commands

The mkfs and mkboot commands check whether a specified disk device is being used by LVM; if so, they display an error message. For these commands to correctly check whether a device is part of a Version 2.x volume group, you must install the following patches:

PHCO_37328
PHCO_37340
PHCO_37394

These patches are delivered in the FEATURE11i bundle.

Serviceguard

To support Version 2.0 volume groups, Serviceguard 11.18 requires the April 2008 patch. Customers requiring Version 2.1 volume group support or Version 2.x cluster lock disks must install the Serviceguard September 2008 patch. For more information, see the HP Serviceguard Version A.11.18 Release Notes.

VxVM 4.1 Commands

Several VxVM 4.1 commands check whether a specified disk device is being used by LVM before overwriting it. For these commands to correctly check whether a device is part of a Version 2.x volume group, you must install the following patch:

PHCO_37836

Required Disk Space

Since LVM is installed with the HP-UX 11i v3 operating environment, it consumes no additional disk space.

MirrorDisk/UX consumes no additional disk space aside from a license key.
