LifeKeeper for Windows Product Requirements

LifeKeeper for Windows

(Server Components)

All servers within a cluster should be running the same version of Windows. See the LifeKeeper for Windows Support Matrix 64-bit versions (x64, no Itanium) of all of the listed OS platforms are supported.

Note: While installing LifeKeeper for Windows on Windows 2008 R2, a dialog box will prompt whether the installer should make the system configuration changes described below. If the installer is not allowed to make these changes, they will need to be made manually after installation is complete.

  • Windows Firewall
  • The Distributed Link Tracking Client must be disabled

For systems running LifeKeeper for Windows and Microsoft FTP Service 7.5 for IIS 7.0, Windows 2008 R2 or later is required.

In addition, if your Windows servers are not in a domain, the Local Security policy setting “Network Access: Let Everyone permissions apply to anonymous users” must be enabled. If the servers are in a domain, then this setting is not required.

LifeKeeper for Windows

(User Interface)

See the LifeKeeper for Windows Support Matrix

MMC 3.0 – download from:
Virtual Environments

The operating system versions listed above are supported for guests running on the following virtual platforms:

  • Amazon EC2 (AWS)
  • VMware vSphere 6.5, 6.7, 7.0 (Please see our Support Matrix for additional information on which versions are supported.)
  • Microsoft Hyper-V Server 2008 R2 or later
Memory The minimum memory requirement for a system supporting LifeKeeper for Windows is based on the memory requirements for the operating system being used. Additional memory is required to run user applications in addition to that required for LifeKeeper for Windows.

LifeKeeper for Windows uses Port 82 for Remote Method Invocation (RMI) communication between the GUI server and client.

The LifeKeeper GUI uses Port 81 for its administration web server which should be different from any public web server. This is used by the GUI when run as a Java applet on a remote client.

In the event of conflict with an existing application, these ports can be changed by editing the RMI_PORT or WEB_PORT entries in the SIOS\LIFEKEEPER\JAVAGUI\SERVER registry key.

LifeKeeper for Windows License One license is required for every server on which LifeKeeper for Windows runs. This applies to both physical and virtual servers.
LAN Manager Recovery Kit Requires the “File and Print Sharing for Microsoft Networks” component (lanmanserver) to be installed on the Windows server. NetBIOS must also be enabled. Otherwise, the LAN Manager resource will not come in service.

GUI Requirements

LifeKeeper for Windows requires that the Java Runtime Environment (JRE) be installed on each server. The 64-bit Windows Java OpenJDK v15.0.1 is installed with the LifeKeeper for Windows Core software. Java OpenJDK v15.0.1 has been fully tested with the LifeKeeper GUI Server and GUI Application components.

Installing and Removing LifeKeeper for Windows

LifeKeeper for Windows uses InstallShield to provide a standard installation interface with choices for Typical, Compact or Custom installation. See the LifeKeeper for Windows Installation Guide for details about installing, removing or upgrading your LifeKeeper for Windows software.

  • Customizations made to LifeKeeper for Windows scripts must be reapplied after upgrading to all releases of LifeKeeper for Windows v8.
  • Make sure you obtain the correct licenses; the old licenses will remain on the system and can be deleted with the license installer tool.
  • SIOS does not support upgrading LifeKeeper for Windows from more than one major version back. If upgrading from a version prior to LifeKeeper for Windows v7.x to LifeKeeper for Windows v8, uninstall the old version of LifeKeeper and reinstall LifeKeeper for Windows v8.

Technical Notes


This program starts LifeKeeper on the current system if it is not currently running. lkstart modifies entries in the %LKROOT%\etc\LKinit.config file pertaining to the LifeKeeper daemons so that they will be respawned if they die.

The –w option, with waitperiod in seconds, can be used to change the timeout interval. Use the –w argument to specify a wait period before the startup.

The LifeKeeper service can also be started using the Microsoft Services MMC under Administrative Tools or from a command prompt using either “sc start LifeKeeper” or “net start LifeKeeper”.

Note: This program must be run from the console.

Running CHKDSK.EXE on LifeKeeper for Windows Protected Volume

Microsoft recommends running the utility chkdsk.exe to check and correct file system or disk errors on volumes that have not been cleanly shut down. However, depending on the extent of errors, the utility may take a very long time to complete. It may take several hours or even days for chkdsk to completely check the volume, or it may hang while checking the volume. Due to these reasons, LifeKeeper for Windows does not run the chkdsk utility on protected volumes. LifeKeeper for Windows does run the Microsoft utility chkntfs.exe to check whether a volume is dirty or not before bringing the volume in service. If a protected volume is found dirty, LifeKeeper for Windows will log an error to the event log.

It is recommended that administrators periodically run chkdsk on LifeKeeper for Windows protected volumes on the server where the volume resource(s) are in service. Administrators should take all the applications using the volume resource(s) out-of-service prior to running chkdsk.

Communication Paths Over Fibre Channel

When building a LifeKeeper for Windows cluster using shared storage, it is important to maintain working communication paths between the nodes in the cluster. Communication paths should be created using TCP communication protocols. Normally, TCP communication paths are built on Ethernet network devices. LifeKeeper for Windows, however, can use any type of connection on which the TCP protocol can run. If a shared storage cluster is being created using a Fibre Channel SAN, it is possible (and desirable) to use the Fibre Channel SAN as a LifeKeeper for Windows communication path.

QLogic provides a miniport driver and an IP driver for Windows that will allow a QLogic Fibre Channel storage adapter to also run the TCP/IP protocol. This, in effect, allows the QLogic Fibre Channel adapter to function both as a storage adapter and as a network adapter. Once this driver is in place, the QLogic card can be configured, as any network card would, using standard network configuration techniques.

QLogic’s driver can be downloaded from the following web site:

Using iSCSI Storage with LifeKeeper for Windows

iSCSI storage can be used as shared storage and protected by LifeKeeper for Windows. For shared storage environments, the iSCSI target device must be configured so that all server initiators have access to the disk. The vendor of the iSCSI storage device provides the interface and commands needed to configure the iSCSI device. A dependency on the Microsoft iSCSI Initiator service (MSiSCSI) should be added to the LifeKeeper service. This will ensure that the shared volume is available before LifeKeeper attempts to access the volume.

To create a dependency on MSiSCSI for the LifeKeeper service, use the registry editor regedt32.exe and select the subkey representing the LifeKeeper service under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LifeKeeper. The service key has a value name “DependOnService” with one value “EISM”. Double-click the value name “DependOnService” to open for editing. When the dialog box appears, add the service name “MSiSCSI” for Microsoft iSCSI Initiator service on a new line and click OK.

To verify that the dependency was created, open Administrative Tools->Services MMC snap-in. Go to LifeKeeper service and double-click to bring up the “Properties” dialog. When the dialog box appears, go to “Dependencies” page and verify that “Microsoft iSCSI Initiator” service is listed along with “LifeKeeper External Interface” in the “depends on” field.

System Load Considerations for Quickcheck and Deepcheck

LifeKeeper for Windows launches a separate thread to monitor each protected resource in the system. These threads operate independently of one another. Typically, system load from Quickcheck and Deepcheck script execution will be randomly distributed. LifeKeeper for Windows also works to distribute resource monitoring load by skipping a Quickcheck execution whenever a Deepcheck for the same resource is scheduled to run at the same time. However, because the check load is randomly distributed, there will occasionally be peaks in system load from resource monitoring. The more protected resources in the system, the larger these peaks will be and the more often they may occur. The largest peak will occur when LifeKeeper is started and Deepcheck scripts for each active resource are first launched. If the server can handle this first load peak in a satisfactory way, then there should not be a performance problem later.

VSS Shadow Copy

LifeKeeper support for VSS Shadow Copy requires that shadow copies must NOT be stored on the LifeKeeper for Windows protected volumes. However, shadow copies may be saved on another non-protected volume.

Known Issues and Restrictions

Known Issue

Missing Job Information warning displayed during mirror creation or deletion

During job creation, the warning “This computer is missing SIOS DataKeeper Job information for the following target volume(s): <vol>” might be displayed in the GUI briefly. The warning will go away after a few seconds. This is a transient condition that can occur during mirror creation and deletion, and does not indicate an error.

Windows 2008 R2

SIOS DataKeeper includes a kernel-mode driver (ExtMirr.sys) which is signed with a SHA-256 signature. If you are installing on a Windows 2008 R2 system that has not been updated with Microsoft hotfixes, it might not be able to boot with such a driver. Please refer to this bulletin from Microsoft for more information, in particular the first event listed which applies to Windows 2008 R2 SP1.

If you are updating SIOS DataKeeper, and your previous version was version 8.6.2 or later, then your system does have SHA-256 driver support (the 8.6.2 driver is signed with SHA-256). In that case you can safely install this version of DataKeeper.


Antivirus Software

Antivirus software may mistakenly detect LifeKeeper binaries as malware. You should configure an exclusion for the folder LKROOT (C:\LK by default) to prevent LifeKeeper utilities from being mistakenly put into quarantine.

SCVMM 2012

If using DataKeeper with SCVMM 2012, you must use SCVMM 2012 SP1.

Server with Microsoft Failover Cluster Installed

LifeKeeper for Windows is not supported on Enterprise or DataCenter class servers with Microsoft Cluster Server or Microsoft Failover Cluster features installed. It should never be the case that two “Clustering” solutions are deployed on the same group of servers. As part of this restriction, LifeKeeper for Windows communication paths will not function using IP addresses ( that are hosted by the Microsoft Failover Cluster Virtual Adapters (Virtual NICs).

FAT File System Support

LifeKeeper for Windows does not support protection for volumes using the FAT or FAT32 file systems.

Fault Tolerant Disk Sets

While LifeKeeper for Windows replicated volumes are supported using Windows fault tolerant disk sets (Software RAID), LifeKeeper for Windows shared volumes are not compatible with Windows fault tolerant disk sets. Fault tolerant disk sets must be set up with dynamic disks and dynamic disks cannot be shared between two systems.

File Share Recovery Kit

  • The File Share Recovery Kit is supported only in an Active Domain environment, not in a Workgroup environment. File share permissions granted to local machine accounts, either in a workgroup environment or a domain environment, will not be preserved during failover because local User IDs are valid only on the local system where they originated; other systems will not recognize them. Even if two local User IDs are spelled the same way on two different machines, they will be treated as two different accounts and valid only on the system where they originated. Domain accounts, on the other hand, are identifiable and usable on any system in the domain.
  • The File Share Recovery Kit will not work if more than 9999 file shares are defined on the system. Any attempt to protect eligible file shares under LifeKeeper for Windows will fail if the total number of user-defined shares exceeds 9999. This restriction also applies to editing file share resources. You will not be able to alter the list of protected shares if more than 9999 shares are defined on the system.

LAN Manager Recovery Kit

Microsoft supports LAN Manager functions only over the first IP address per network interface card (Microsoft bug SRX#9704116-48). This prohibits using LAN Manager functions over LifeKeeper for Windows protected IP addresses. Therefore, the only way to switch over an alias computer name using the TCP/IP protocol is to allow dynamic IP#-to-LAN Manager name mapping for your clients. The recommended solution is to use a WINS server. You will need to make the LifeKeeper for Windows servers (and all computers accessing the protected LAN Manager name) WINS clients of the same WINS server.

Low Virtual Memory Degrades System State

LifeKeeper for Windows depends on memory being available when it is needed. If your system is reporting that it is low on virtual memory, that need must be resolved immediately.

A virtual memory shortage serious enough to degrade or delay communications and other internal system functions will very likely cause LifeKeeper for Windows to malfunction. For instance, deepcheck of TCP/IP communication resources may be impacted enough to cause a false failure, and thus a failover of the resource to the backup server.

If LifeKeeper for Windows communication with other servers in the cluster is degraded, it could cause a manually initiated switchover to fail. However, this will not affect LifeKeeper for Windows ability to fail over protected resources when a server completely fails.

GUI interoperability

The LifeKeeper GUI may only be used to administer LifeKeeper on Windows servers. Note that you can connect to and monitor a LifeKeeper for Linux cluster. However, performing administrative tasks such as creating resources, editing properties, bringing servers in and out of service, is not supported at this time.

Discontinuing Serial Port Communication Paths

LifeKeeper for Windows discontinued support for TTY communication paths in Version 7.2. Though SIOS does not recommend it, if currently using TTY communication paths, this option can be re-enabled by removing the (#) symbol on the TTYCA.EXE line in the /etc/lkinit.config file as shown below:

# … /bin/TTYCA.EXE|-t 1 X X X X X X <=
(TTY Comm Paths Disabled)
… /bin/TTYCA.EXE|-t 1 X X X X X X <=
(TTY Comm Paths Enabled)

To enable or disable the TTY communication path feature, the LifeKeeper service must be stopped and restarted after editing lkinit.config. To stop LifeKeeper, run command {c:\lk}\bin\lkstop.exe –f (c:\lk being the LifeKeeper installation path). Make sure the GUI is closed and all processes associated have stopped. Restart LifeKeeper by entering {c:\lk}\bin\lkstart.exe.

The TTY technology is obsolete. TTY communication paths are not supported and should be replaced with TCP/IP communication paths.

Console Application Management

Launching console applications from LifeKeeper for Windows is not supported on Windows Server 2008 and later. Server architecture and security improvements in Server 2008 including UAC and memory management, prevent background processes such as LifeKeeper for Windows from starting console applications.

Bitlocker Does Not Support DataKeeper

According to Microsoft, Bitlocker is not supported to work with Software RAID configurations. Since DataKeeper is essentially a software RAID 1, Microsoft does not support Bitlocker working with DataKeeper.

Frequently Asked Questions

Can I change my LifeKeeper for Windows configuration database setting including resource values without reinstalling LifeKeeper for Windows or rebuilding my resources?

Yes. Use the lk_chg_value.ksh command.

Can I upgrade my existing LifeKeeper for Windows hierarchies from a previous version of LifeKeeper for Windows to v8?

You may upgrade your existing LifeKeeper for Windows software while preserving your resource hierarchies. Please refer to the Upgrading LifeKeeper for Windows topic for the correct upgrade procedure. Note: SIOS does not support upgrading LifeKeeper for Windows from more than one major version back. If upgrading from a version prior to LifeKeeper for Windows v7.x to LifeKeeper for Windows v8, uninstall the old version of LifeKeeper and reinstall LifeKeeper for Windows v8.

Does LifeKeeper for Windows operate in a cluster with Microsoft Cluster Services (Windows 2003) or Windows Server Failover Cluster (Windows 2008 and later)?

No. LifeKeeper for Windows v8.0.1 is an alternative clustering product and does not support either Microsoft Cluster Service or Windows Server Failover Clustering.

Does LifeKeeper for Windows require that all servers in the cluster be identically configured?

No. As long as all servers are powerful enough to run any application that may run on them as the result of a failover operation and meet all other LifeKeeper for Windows requirements, a cluster can be built. LifeKeeper for Windows does not require identical hardware, but the software should be the same and configured with the same service pack levels.

Does LifeKeeper for Windows support 64-bit environments?

Yes. LifeKeeper for Windows supports only 64-bit platforms.

How do I change permissions on LifeKeeper for Windows protected File Share resources?

The EditFileShareResource utility can be used to update a file share resource with all current file shares and permissions on the associated volume(s). This can be useful in environments where there are a large number of file shares, and file shares have been added or deleted since the resource was created or permissions have been modified. Using the utility can prevent the need to delete and re-create the file share resource. The EditFileShareResource utility is located under %LKROOT%\bin directory.

To invoke the utility, on the command line enter:

EditFileShareResource <Tag name>

where <Tag name> is the tag name of a file share resource that is currently in service.

The utility protects all eligible file shares defined on the volumes that are associated with the file share hierarchy. It deletes any previously protected shares that have been deleted from the system and adds newly defined shares (meeting the eligibility criteria) to the list. It will also update the file share permissions defined on the file share.
