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
Quorum/Witness
allowing resources to be brought in service in cases where the witness
Packageserver(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, thein-service node.

Client Platforms and Browsers

Client Platforms and Browsers
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 andChrome 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.

Storage and Adapter Options
For a list of the disk array storage models and adapters currently supported by LifeKeeper in sharedstorage configurations as well as their type of certification, see the Storage and Adapter Options
topic. Details about driver versions and other configuration requirements for these arrays andadapters are listed in the Storage and Adapter Configuration topic.

Known Issues
