We have a client who had the following requirements:
OCR and voting disk is configured on CVM raw volumes or CFS and managed by VCS, it is not possible to place ASM disk group as a dependency in main.cf. So what I’ve done is that I placed the file system housing rdbms/grid binaries as cluster resource group. That mount point also depends on the public interface (there are two private interconnects but those were not set as resource groups, RAC uses the same cluster interconnects as SFRAC).
To complete the integration, questions now is on configuring the CSSD resource manually. Actually this could be done, based on my understanding of the software stack, by adding cssd to the same group I mentioned above (the mount point housing binaries), this resource will use the standard CSSD Start/Stop/Monitor/Clean available as /opt/VRTSvcs/rac/bin/cssd-XXX.
This should work, conceptually! I just need to make sure that this is solid enough to use for a global cluster setup.
