First Cluster Node Installation
Before starting the SAP Installation, make sure you have created a DNS Type A record for SAP Virtual Instance Host at DNS Server as we described in an earlier step.
You will perform a regular SAP Windows Cluster installation. For more information regarding SAP installation on Microsoft Windows Failover Cluster, please refer to official SAP documentation here.
Current Host Server
Before you begin, make sure the primary server is the Current Host Server.
Grant the Cluster Name Object (CNO) Permissions on the OU
In order to avoid possible security issues with creating the cluster objects in the next steps, it is advisable to grant the CNO permissions on the OU that contain the computer objects. This can be done on one of the domain controllers by a domain admin.
In the next steps we will install the ASCS/ERS cluster on the first cluster node. Follow along with the screenshots below.
Log on as Domain Admin user at the first Windows Cluster instance and run the SAP Installation through sapinst.
The computer will log off at this point. Log back on to continue the installation.
It may take a few moments before the next screen appears.
The SAP System ID is just three letters that identify this system. The Network Name for ASCS and ERS are the same as the names we entered in DNS in an earlier step. The DataKeeper Volume D is the DataKeeper Volume Resource we created earlier.
Specify the folder where you have downloaded the SAP software.
Click Next and it will find your package location.
Click Next to continue.
Notice at this point there are two cluster resource groups with related resources being created in WSFC.
