Since I do not know your implementation of SAP but more than likely, it either will break SAP or will not stop the nfs client. Or even worse, it may do both.

SAP, in my datacenter implementations, uses NFS to access /sapmnt/ directory where the SAP binaries are located. So, short of stopping SAP, you can not unmount this mountpoint. Although, sometimes, strangely, nfs client, when requested to stop, attempt to unmount it and leave you in a limbo where there is nothing else but reboot to clear it up.

My suggestion, don't do it unless the packages are failed over to the other node.
