Stopping VCS does not unregister port f from GAB membership

In an SF Oracle RAC cluster with all the CFS resources under VCS control, when you stop VCS, all the CFS resources must go down cleanly and CFS must unregister port f from GAB membership.

Oracle 10g Cluster Ready Services (CRS) does not clean up all its processes when it is stopped. Now, when you stop VCS, all the CFS resources go down. However, due to the left over Oracle processes, CFS does not unregister port f from GAB membership.

Workaround: Perform the following steps to bring down port f.

1. Kill all the Oracle processes.

   # kill -9 `ps -u oracle|awk '{print $1}'`

2. Verify that all CFS files systems are unmounted.

   # mount | grep cluster

3. Unregister port f from GAB membership.

   # fsclustadm cfsdeinit
