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 (Including VMWare virtual hard disks)
- File Systems (ext3, ext4, vxfs, xfs and nfs) Note: btrfs is not currently supported by the SIOS Protection Suite for Linux. For detailed information see LifeKeeper Core – Known Issues / Restrictions.
- Communication Resources (TCP/IP)
- Database Applications
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.

| 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) v9.4.0. OpenJDK is compatible with SPS-L v9.4.0, therefore customers may use this version or any compatible version of OpenJDK with SPS-L v9.4.0. 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. | |

Hot Fixes and Add-on Support Packages
The patches are located here.
| steeleye-lkHOTFIX-Gen-LB-PL-7172-9.5.1-7154.1.x86_64.rpm | Current Version addresses: PL-13953: Restore should return success even if daemon process is running. PL-14238: Check_exist_process sometimes doesn’t work after reboot. Previous version (steeleye-lkHOTFIX-Gen-LB-PL-7172-9.5.1-7154.x86_64.rpm) addressed: PL-7172: Support for load balancers in Microsoft Azure and Google Cloud Platform. |
The Generic Application Recovery Kit for Load Balancer Health Checks provides a mechanism to receive and respond to a TCP health check probe for target instances of load balancers in Microsoft Azure (Azure) environments and Google Cloud Platform (GCP) environments. When updating the previous version of the HOTFIX use rpm -Uvh. See the readme.txt provided with this patch for further details on installing the patch and how to update all scripts in the cluster. |
| steeleye-lkHOTFIX-core-PL-11771-9.6.0-7333.x86_64.rpm | This patch fixes a problem related to failures during switchover of NFS hierarchies. In particular, in SAP environments, the fuser process has been observed to hang. | This patch avoids problematic hangs related to the fuser process. |
| steeleye-lkHOTFIX-ROUTE53-PL-11129-9.6.0-7333.noarch.rpm | Addresses failure of the Route53 recovery kit when accessing the AWS CLI from nodes without internet access or configured AWS role. | This patch exports NO_PROXY within the value_domain script prior to attempting an AWS CLI call. |
| steeleye-lkHOTFIX-SAP-PL-13003-9.6.0-7333.1.x86_64.rpm |
|
1) This patch fixes an issue where the properties panel for an ERS resource created prior to LifeKeeper 9.4.0 does not display the status of the protected instance on both cluster nodes. (Added in patch revision 7333.1) 2) This patch allows SIOS SAP HA Cluster Connector routines to communicate successfully with the SAP HA Script Connector Library on the affected SAP kernel versions and patch levels listed above. |
| steeleye-lkHOTFIX-DR-PL-13245-9.6.0-7333.noarch.rpm | Increased frequency of the Emergency message on unique identifier requirement for the mirrored device. | This patch provides an updated DRBase.pm file that limits the Emergency message to one quickCheck cycle for the resource per LifeKeeper start. A unique identifier is still required to protect the data from loss or corruption. |
| steeleye-lkHOTFIX-core-PL-7770-9.6.1-7412.noarch.rpm | This patch fixes a problem related to the lklicmgr command not properly recognizing licenses for the HANA ARK and showing them as unknown. | This patch avoids erroneous unknown status messages for installed HANA ARK licenses. |
| steeleye-lkHOTFIX-NFS-CE-2925-9.5.2-7301.noarch.rpm | NFS resource hierarchy switchover hangs when exportfs hangs. | This patch will wait up to 30 seconds for the exportfs command to complete before aborting the action. A notification will be provided to the user that the process appears to have hung and may require a system reboot to clear the hang. |
| steeleye-lkHOTFIX-systemd-PL-15331-9.6.2-7477.noarch.rpm |
|
This patch fixes lifekeeper.service file related issues. |

Installation and Configuration
See the SIOS Protection Suite Installation Guide for complete installation and configuration information.
Upgrades
LifeKeeper can be upgraded to Version 9.5.x from either LifeKeeper Version 9.3.x or Version 9.4.x. If upgrading from a version other than 9.3.x or 9.4.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 9.3.x or 9.4.x, then perform the upgrade to 9.5.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.
Known Issues
