Please see the LifeKeeper for Linux Planning and Installation Guide for specific instructions regarding the configuration of your LifeKeeper hardware and software.

Hardware Requirements

Servers. This recovery kit requires two or more computers configured in accordance with the requirements described in the LifeKeeper Release Notes and the LifeKeeper Planning and Installation Guide, which are shipped with the product media.

Data Storage. The LVM Recovery Kit can be used in conjunction both with shared storage and with replicated storage provided by the LifeKeeper Data Replication product. It cannot be used with network attached storage (NAS). Otherwise, the kit has no specific requirements on storage configurations beyond the requirements of the recovery kit protecting the application sitting on top of the logical volume(s).

Software Requirements

Operating System. LVM is included in all major Linux distributions. See the LifeKeeper Release Notes for a list of supported distributions and LVM versions.

Logical Volume Manager. The recovery kit installation requires that the lvm rpm package be installed. This release of the LifeKeeper Logical Volume Manager Recovery Kit supports LVM version 1. The specific versions of LVM supported are those delivered by the Linux distributions.

LifeKeeper Software. You must install the same version of LifeKeeper core software and any recovery kits, including the LVM Recovery Kit, and any patches on each server. Please refer to the LifeKeeper Release Notes for specific LifeKeeper requirements.

LifeKeeper for Linux Logical Volume Manager Recovery Kit. The Logical Volume Manager Recovery Kit is provided on a CD. It is packaged, installed and removed via the Red Hat Package Manager, rpm. The following rpm file is supplied on the LifeKeeper for Linux LVM Recovery Kit CD: steeleye-lkLVM-<Version>.rpm

During package installation, checks are made to ensure that supported versions of both the LifeKeeper Core package and the LVM package are present on the system where the LVM Recovery Kit is being installed. The LifeKeeper for Linux Release Notes contains information on the required versions of these packages.

Refer to the LifeKeeper for Linux Planning and Installation Guide for instructions on how to install or remove the LifeKeeper Core software and the LVM Recovery Kit.

The LVM Recovery Kit must be installed on each server in the cluster on which LVM is being used to manage disk resources that are to be protected by LifeKeeper.

The LVM Recovery Kit must be installed prior to the hierarchy creation and extension of applications that sit on top of an LVM volume.
