Do you still really need heartbeat v1???
There are some advanced SAP Resource-Agents for heartbeat v2, which
also include monitoring and service restarts.
The problem with your own(?) RA is it could damage your data, if the
unmounts are not work properly (failing due to open files). This could
cause dual mounted file systems - ugly!
