I have a couple of clusters producing unexpected behaviour. The problem is the same for both.
Two nodes in the cluster, all resources are on Node A. SAP section of the cluster fails over to Node B for no apparent reason, SQL stays on A.
Node A and Node B can see each other no problem. However, users cannot connect to the B Node, only A.
Node B doesn't failback and if you try to make it by using Move Group it fails and switches back to Node B.
To make it move back you have to shut SAP on Node B and Node A. It will then let you move it back.
Any help or advice much appreciated.
