Hello,

a new version of the "Deploying Highly available SAP servers using RHCS" whitepaper is available at https://access.redhat.com/knowledge/refarch/deploying-highly-available-sap-servers-using-red-hat-clu...

In appendix A of this whitepaper you can find an example cluster configuration showing how to use Red Hat Clustering to set up a SAP HA environment.

Hi,

I would choose "SAP Instance"..

See the document from below link (Page 45)

*Deploying Highly Available SAP® Servers using Red Hat*

You can also try using "luci" for cluster configuration... It is a browser based tool to configure cluster (you may already aware of it...)

Added the three sap instances,and everyone content "sap instance name"\"Sap Executeable DIR"\"Sap start profile name"\""sap profile Dir", and we add these to services,but we cann't enable the services.
