SIOS Product Descriptions
LifeKeeper for Linux
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, vxfs, xfs and nfs) Note: btrfs is not currently supported by the SIOS Protection Suite for Linux. For the detailed information see Troubleshooting > Known Issues and Restrictions.
- 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
DataKeeper for Linux
The SIOS DataKeeper product:
- Provides volume-based synchronous and asynchronous data replication.
- Integrates into the LifeKeeper Graphical User Interface for administration and monitoring.
- Automatically resynchronizes data between source and target servers at system recovery.
- Monitors the health of underlying system components and performs local recovery in the event of failure.
- Allows manual resource switchovers and failovers of mirrored volumes.
- Can be easily upgraded to provide high availability clustering and automatic failover and recovery using a license key to enable new functionality.

New Features of SIOS Protection Suite for Linux Version 9
| IMPORTANT NOTICE: As our valued customer, we want to proactively notify you of an issue that we discovered in the md/raid1 kernel module of several Linux releases. Due to this issue, a partial resync of data within supported versions (v9.3.2 – v9.5.1) of SIOS Protection Suite for Linux with DataKeeper cluster nodes may NOT resync all blocks. Refer to this link for more information. | |
| LifeKeeper Core | Red Hat Enterprise Linux 7.6 is supported. Note: DataKeeper asynchronous mirrors are not supported because of a Linux kernel bug. |
| CentOS 7.6 is supported. Note: DataKeeper asynchronous mirrors are not supported because of a Linux kernel bug. |
|
| Oracle Linux Version 7.6 is supported. Note: DataKeeper asynchronous mirrors are not supported because of a Linux kernel bug. Note: Unbreakable Enterprise Kernel Release 5 (UEK R5) is NOT supported. (i.e. DataKeeper resource does NOT work on UEK R5.) |
|
| Linux Enterprise Server 12 SP4 is supported. Please see this IMPORTANT NOTICE. | |
| SUSE Linux Enterprise Server 15 is supported. Note: Upgrading from one kernel version to another major version such as from SLES 12 to SLES 15 is NOT supported. (i.e DataKeeper resource does NOT work when upgrading from SLES 12 to SLES 15.) |
|
| OpenJDK v10.0.2 is supported. SIOS has tested OpenJDK v10.0.2 downloaded from https://jdk.java.net/10/ with SIOS Protection Suite for Linux (SPS-L) v9.3.2. OpenJDK is compatible with SPS-L v9.3.2, therefore customers may use this version or any compatible version of OpenJDK with SPS-L v9.3.2. If a customer encounters an issue due to the OpenJDK version, SIOS may recommend using a newer version of OpenJDK or the OracleJDK included in SPS-L package. |
|
| Install | The -s option for saving the current setup configuration has been added to the setup command. |
| RHEL7.6 also does not support DataKeeper’s asynchronous mode. The warning message is output by setup. | |
| DataKeeper | Wait For Previous Source for multi-target mirrors. For a multi-target mirror DataKeeper keeps track of the last server, aka previous source, that had the mirror in-service. When there is a failover, the bitmap from the previous source is required to keep all of the targets in-sync. DataKeeper will now automatically wait for the previous source to join the cluster before resuming replication to any target. This allows the bitmap from the previous source to be merged so that only partial resyncs are necessary. |
| Unnecessary synchronization is avoided in the environment with three or mode nodes. | |
| Add updated messages for “wait for source” in GUI and mirror_status. | |

Client Platforms and Browsers
The SPS web client can run on any platform that provides support for Java Runtime Environment JRE8 update 51. The currently supported browsers are Firefox (Firefox 51 or earler) and Internet Explorer running on Linux, Windows Server 2008 R2, Windows Server 2012 R2, Windows Server 2016, Windows 7, Windows 8 or Windows 10 with JRE8 update 51. Other recent platforms and browsers will likely work with the SPS web client, but they have not been tested by SIOS Technology Corp. In addition, particular features of each browser have not been tested.
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.
Installation and Configuration
See the SIOS Protection Suite Installation Guide for complete installation and configuration information.
Upgrades
LifeKeeper can be upgraded to Version 9.3.x from either LifeKeeper Version 9.1.x or Version 9.2.x. If upgrading from a version other than 9.1.x or 9.2.x, the older version will need to be uninstalled, and SIOS Protection Suite for Linux will have to be reinstalled. An alternative to uninstalling the older version would be to upgrade from the older version to 9.1.x or 9.2.x, then perform the upgrade to 9.3.x.
Storage and Adapter Options
For a list of the disk array storage models and adapters currently supported by SPS in shared storage 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 and adapters are listed in the Storage and Adapter Configuration topic.
Technical Notes
We strongly recommend that you read the Technical Notes section concerning configuration and operational issues related to your SPS environment.
Location of pdksh Has Changed
The location of pdksh installed by the SPS setup script in versions prior to 8.1 has changed. The pdksh was previously located at /usr/bin/ksh. It is now located at /opt/LifeKeeper/bin/ksh. Any customer written scripts that relied on the pdksh version installed by the SPS setup (/usr/bin/ksh) should be modified to reflect the new path.
Known Issues
See Known Issues and Restrictions in the Troubleshooting section of SIOS Protection Suite for Linux Technical Documentation and the DataKeeper Troubleshooting section.
