Disable oracle database direct NFS

The DB was migrated to sun filer.The database came up ,but there were issues in bringing up hyperion shared services.Also we noticed that "alter system switch logfile" command was hanging.There were entries in alert log as below,

===
Direct NFS: mount complete dir /vol/XXXXXXX
Direct NFS: mount complete dir /vol/XXXX   fsport 2049

We disabled direct NFS on database,which resolved the issue.
1. mv ${ORACLE_HOME}/lib/libodm11.so ${ORACLE_HOME}/lib/libodm11.so.bak
2. rm ${ORACLE_HOME}/lib/libodm11.so
3. ln -s ${ORACLE_HOME}/lib/libodmd11.so ${ORACLE_HOME}/lib/libodm11.so
