Important!!
Read This Document Before Attempting To Install Or Use This Product!
This document contains last minute information that must be considered before, during and after installation.
This release notes document is written for the person who installs, configures and/or administers the LifeKeeper for Linux product. The document contains important information not detailed in the formal LifeKeeper documentation set such as package versions and last-minute changes to instructions and procedures as well as a link to the Troubleshooting section for product restrictions and troubleshooting hints and tips that were discovered through final product testing. It is important that you review this document before installing and configuring LifeKeeper software.
The LifeKeeper product includes fault detection and recovery software that provides high availability for file systems, network addresses, applications and processes running on Linux. LifeKeeper supports the configuration and switchover of a given application across multiple servers. The servers on which the application is configured are assigned priorities to determine the sequence in which the application will move from server to server in the event of multiple failures.
LifeKeeper for Linux provides switchover protection for a range of system resources. Automatic recovery is supported for the following resource types:
Processes and Applications
Shared Storage Devices
File Systems (ext3, ext4, reiserfs, vxfs, xfs and nfs)
Communication Resources (TCP/IP)
Database Applications
LifeKeeper for Linux provides Disaster Recovery protection for the following resource types:
Linux Multi-Site Cluster configurations in which data from a shared storage cluster is replicated to a disaster recovery site
LifeKeeper for Linux is bundled and runs on 32-bit and 64-bit systems (x86, AMD64 and EM64T systems). The LifeKeeper Core Package Cluster includes the following installable packages:

Providing an even higher level of protection, the Quorum/Witness Package allows system failover to occur with a greater degree of confidence. A quorum/witness node allows local site failovers and failovers to nodes across a WAN to be done with a greatly reduced risk of “split-brain” situations, only allowing resources to be brought in service in cases where the witness server(s) also concurs regarding the status of the failing node. This will prevent failovers from happening due to simple communication failures between nodes when those failures do not affect the overall access to, and performance of, the in-service node. |
|
|
The LifeKeeper Recovery Kit for HP XP Cluster Extension provides clustering support for file systems that are being replicated by XP Continuous Access and provides protection for applications running on servers attached to XP storage arrays, ensuring that consistent and concurrent data copies on these arrays can be accessed by the applications when needed. |

Virtual Environments |
LifeKeeper for Linux is architected to be hypervisor-independent as long as the guest operating system running within the virtual machine is one of the supported versions listed above. The following virtual environments are examples of where SteelEye Protection Suite for Linux has been deployed:
Please refer to the document LifeKeeper for Linux in VMware ESX Server Virtual Machines, Configuration Guidelines" for more detailed configuration requirements and limitations. LifeKeeper for Linux running in a Microsoft Virtual Server 2005 R2, VMWare Server 1.0 and Citrix XenServer virtual machine is supported with the following cluster storage options: NAS and SteelEye DataKeeper. All of these storage options can be used in virtual-to-virtual, virtual-to-physical and physical-to-virtual failover configurations. The configuration of NAS and DataKeeper in a virtual machine environment is exactly the same as in a physical machine environment. Fibre channel SAN and shared SCSI cluster configurations are not supported with LifeKeeper for Linux running in a Microsoft Virtual Server 2005 R2, VMWare Server 1.0, KVM and Citrix XenServer virtual machine. |

The LifeKeeper web client can run on any platform that provides support for Java Runtime Environment (JRE) 6. The currently supported configurations are Firefox, Internet Explorer and Chrome on Linux, Windows 2000, Windows Server 2003, Windows 2008 R2, Windows XP, Windows 7 or Windows Vista with JRE 6. Other recent platforms and browsers will likely work with the LifeKeeper web client, but they have not been tested by SIOS Technology Corp.
You should specify all the hostnames and addresses in your cluster in the client machine’s local hosts file (usually /etc/hosts or C:\windows\system32\drivers\etc\hosts). This minimizes the client connection time and allows the client to connect even in the event of a Domain Name Server (DNS) failure.
