Dear Expert,
I was doing a PoC for SAP Netweaver 7.5 [A(S)CS/ER] HA Configuration on SLES 12 SP2 for SAP Application but it never worked. I have tried to follow SuSE Offical guide step by step but it never worked. I never faced this kind of issue with Red Hat or any other HA software vendor like VCS or HPE Service Guard.
