Updated -



Applicable Environments

  • Red Hat Enterprise Linux (RHEL) with the High Availability Add-On

Useful References and Guides


This guide offers Red Hat's policies and requirements around managing an SAP HANA deployment with a RHEL High Availability (HA) cluster. Users of RHEL High Availability clusters should adhere to these policies in order to be eligible for support from Red Hat with the appropriate product support subscriptions.


Scope of Red Hat support with SAP software resources managed by a cluster: Refer to Red Hat's policy on Management of applications that Red Hat does not ship for further details on Red Hat's scope of support applicable to SAP software deployments in a RHEL High Availability cluster.

The focus of Red Hat's assistance may be limited to functionality of the High Availability software and the SAP resource-agent(s). In some cases SAP's input may be necessary to diagnose the nature of a problem - even if the problem originates in the resource-agent Red Hat ships. Solutions to problems with RHEL High Availability + SAP HANA deployments may be dependent upon some input or deliverable from SAP in cases where the issue can not be solved adequately through RHEL High Availability without SAP's assistance.

Red Hat subscriptions for SAP HANA support: Red Hat provides support for RHEL High Availability resource-agents managing SAP HANA deployments through the following subscriptions:

  • RHEL for SAP Solutions
  • RHEL for SAP HANA (no longer sold)

One of these subscriptions for each cluster node is required in order for Red Hat to assist with RHEL High Availability management of SAP HANA.

Supported platforms for SAP HANA on RHEL High Availability: Red Hat support for its software supporting the SAP HANA solution stack for Scale-Up/Scale-Out System Replication environments including RHEL High Availability and its resource-agents for SAP software - largely follows the policies laid out for RHEL High Availability and RHEL:

However in public-cloud deployments, Red Hat's support for this SAP HANA solution stack is limited to only the following cloud platforms:

  • Amazon Web Services Elastic Cloud (AWS EC2)
  • Microsoft Azure
  • Google Cloud Platform

Other cloud provider platforms are not supported by Red Hat for this solution at this time. Please contact Red Hat Support if you are interested in running SAP HANA on another cloud platform.

Supported deployment types

  • Single database deployments
  • MCOD (Multiple Components One Database)
  • MDC (Multiple Database containers),
  • MCOS (Multiple Components One System) is only supported if all databases running on the hosts are replicated and the replication is always to the same secondary node (for Scale-Up only)

Check the SAP Note 2235581 for certified/supported combinations of RHEL and SAP HANA releases.

For the list of x86_64 and IBM POWER servers, storage systems and cloud instance types that are certified for running SAP HANA Scale-Up and Scale-Out installations, please check Certified and Supported SAP HANA® Hardware Directory

Multitier System Replication is supported for SAP HANA Scale-Up and SAP HANA Scale-Out System Replication HA setups, and is only possible if additional SAP HANA instances are not managed by an HA cluster. The HANA instances running outside of the cluster must be registered manually and re-registered after each takeover.

Multi-Target System Replication is supported for SAP HANA Scale-Up and SAP HANA Scale-Out System Replication HA setups, and is only possible if additional SAP HANA instances are not managed by an HA cluster. The HANA instances running outside of the cluster must be registered manually and re-registered after each takeover.

For further details on using RHEL HA for SAP HANA in context of CCSP, please see KB 3751271.

Additional technical requirements for SAP HANA System Replication HA deployments:
The following conditions apply for Red Hat to provide support:

  • 2-Node clusters are supported for SAP HANA Scale-Up System Replication environments.
  • Up To 16/32 node (depending on pacemaker version) clusters are supported for SAP HANA Scale-Out System Replication environments.
  • Users and groups used by SAP HANA must be identically defined on all nodes (use the same UIDs/GIDs, home directories, ...).
  • The SAP HANA instances on all nodes must be configured with the same SID..
  • Using Full Sync Replication is possible, but due to the way Full Sync Replication works some functionality of the cluster will be restricted (for example the automatic start of the HANA instances on both nodes when the cluster is started will not work and the HANA instance on the secondary node will have to be started manually for the cluster to be able to resume operation if Full Sync Replication is enabled.). To check Full Sync Replication state you can run command hdbcons -e hdbindexserver "replication info"|egrep "(ReplicationFullSync|enable_full_sync)" as SAP HANA administrative user.
  • Active/Active (Read Enabled) SAP HANA System Replication setups are possible with SAP HANA 2.0 using version 0.152.17 or later of the SAPHANA and SAPHanaTopology resource agents. To enable such setups a second IPaddr2 resource and a co-location constraint have to be added to manage the second IP address.* (Scale-Up Only)*
  • If the cluster nodes are installed in different data centers or data center areas, the environment must match both
  • Time on all cluster nodes must be in sync (using NTP) or some other time synchronization method) - resource agents require the time to be the same on all nodes for proper operation.
  • Each cluster node must have a local installation of SAPHostAgent and the version of SAPHostAgent across the cluster must be the same. SAPHostAgent is installed with the HANA installation, if not already installed.
