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.

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

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.
