LifeKeeper for Linux is supported running virtual machines of the following virtualization technologies as long as the guest operating system running within the virtual machines is one of the supported versions listed above.
l VMware ESX Server 3.0
l VMware ESX Server 3.5
l VMware vSphere 4 and 4.1
l Microsoft Virtual Server 2005 R2l VMWare Serverl Citrix XenServer
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 virtual machine issupported with the following cluster storage options: NAS and SteelEye Data
Replication. All of these storage options can be used in virtual-to-virtual, virtual-tophysical, and physical-to-virtual failover configurations. The configuration of NAS
and data replication in a Microsoft Virtual Server 2005 R2 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 virtual machine.
Currently, shared storage clusters are not supported. Clusters created with
SteelEye Data Replication or network attached storage should operate correctly.

in/optClient Platforms and Browsers
The LifeKeeper web client can run on any platform that provides support for Java Runtime
Environment J2RE 1.4 or later. The currently supported configurations are Firefox 1.5, 2 or 3 andInternet Explorer 6, 7 or 8 on Linux, Windows 2000, Windows Server 2003, Windows 2008 R2,
Windows XP, Windows 7 or Windows Vista with J2RE 1.4, JRE 5 or 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.

the install will not finish correctly.
libXau-1.0.5-1.el6.i686.rpm
libxcb-1.5-1.el6.i686.rpm
libX11-1.3-2.el6.i686.rpm
libXext-1.1-3.el6.i686.rpm
libXi-1.3-3.el6.i686.rpm
libXtst-1.0.99.2-3.el6.i686.rpm

The multipathd daemon will log errors in the error log when the nbd driver is
Bug loaded as it tries to scan the new devices

RHEL6: LifeKeeper core gets in a state where it cannot stop or start
When running LifeKeeper with RHEL 6, the LifeKeeper core gets into a state where
LifeKeeper cannot be stopped or started.
Workaround: If LifeKeeper gets into this state (where lkstart reports that "LifeKeeper
should already be running" but "ps" or "lktest" shows no daemons are running), execute thefollowing commands:

initctl stop lifekeeper
rm /etc/init/lifekeeper.conf
rm /etc/init/lk-logmgr.conf
rm /etc/init/lk-logmgr-kill.conf
rm /etc/init/lkstart.conf
lkstartMount point choice list shows duplicate values for each entry
When attempting to create the resource hierarchy, the mount point selection window shows
Bug duplicates.

Workaround: Select either of the mount points in the list to create the resource hierarchy.
The duplicate entries will not affect the hierarchy creation.

1563 Could not start balance on Target when Compression Level is set on RHEL 6 (64-bit)

Solution: To resolve the issue, please install the 32-bit zlib packages from RHEL 6 whenusing RHEL 6 (64-bit).
Mirrors automatically started during bootOn some systems (for example those running RHEL 6), there is an AUTO entry in theconfiguration file (/etc/mdadm.conf) that will automatically start mirrors during boot(example: AUTO +imsm +1.x –all).
Solution: Since LifeKeeper requires that mirrors not be automatically started, this entry will
Bug need to be edited to make sure that LifeKeeper mirrors will not be automatically started
1534 during boot. The previous example (AUTO +imsm +1.x –all) is telling the system toautomatically start mirrors created using imsm metadata and 1.x metadata minus all others.
This entry should be changed to "AUTO -all", telling the system to automatically start
everything “minus” all; therefore, nothing will be automatically started. Important: If
system critical resources (such as root) are using MD, make sure that those mirrors arestarted by other means while the LifeKeeper protected mirrors are not.
