DBA’s you must have come across below error post cloning a RAC database to single instance node

RAC database shared server storage must have been managed by third party cluster vendor tools like VERITAS or so

Refer below steps to resolve it 

Issue:

ORA-17612: Failed to discover Oracle Disk Manager Library, return value 2



Solution: 

Step 1: Make sure proper .profile/environment variables & pointing to new/cloned ORACLE_HOME
-ORACLE_HOME
-ORACLE_SID
-LD_LIBRARAY_PATH
-LIBPATH
-PATH

Step 2: Perform below on destination server where cloning has taken place

cd $ORACLE_HOME/rdbms/lib
make -f ins_rdbms.mk rac_off





Step 3: 
cd $ORACLE_HOME/rdbms/lib
make -f ins_rdbms.mk ioracle


Step 4: After detaching binaries from RAC configuration, move below 4 RAC libraries to backup

#cd /oracle_temp/product/9.2.0/lib
#ls -lrt libodm9.a
-rw-r--r--    1 oracle9i oinstall       7386 May 13 2002  libodm9.a
#mv libodm9.a libodm9.a_old
#ls -lrt libodm9.so
-rw-r--r--    1 oracle9i oinstall      48077 Jun 14 2008  libodm9.so
#mv libodm9.so libodm9.so_old
#ls -lrt libodmd9.a
-rw-r--r--    1 oracle9i oinstall       7386 May 13 2002  libodmd9.a
#mv libodmd9.a libodmd9.a_old
#ls -lrt libodmd9.so
-rw-r--r--    1 oracle9i oinstall       6470 Oct 26 2004  libodmd9.so
#mv libodmd9.so libodmd9.so_old





Step 5: Now copy the above 4 library files from the single node binary of similar OS & DB Version

#cp /oracle/product/9.2.0/lib/libodm9.a  .

#cp /oracle/product/9.2.0/lib/libodm9.so  .

#cp /oracle/product/9.2.0/lib/libodmd9.a  .

#cp /oracle/product/9.2.0/lib/libodmd9.so  .



Step 6:

-Copy/Ensure init.ora , listener ,tnsnames , password have been copied to cloned ORACLE_HOME

-Remove/unset Cluster parameters from parameter file e.g.

cluster_database=FALSE

thread=0

-Make sure all dump/audit location folders are accessible

Step 7:

Relink database binaries

#relink all
 



 Step 8:

Startup the database
