SRVCTL add database fails with osdbagrp error 

This seems to have caused missing ASM group entry in config.c

 $ srvctl add database -d ERPDBA -o /erp_base/app/11.2.0 -p +DATA/spfileERPDBA.ora -c RAC -a EBS
 PRCR-1006 : Failed to add resource ora.ERPDBA.db for ERPDBA
 PRCT-1011 : Failed to run "osdbagrp". Detailed error: null

 You can fix it by following below action plan.

 $ cd $ORACLE_HOME/rdbms/lib
 $ cp config.o config.o.backup
 $ rm -f $ORACLE_HOME/rdbms/lib/config.o
 $ make -f $ORACLE_HOME/rdbms/lib/ins_rdbms.mk $ORACLE_HOME/rdbms/lib/config.o
 $ cd $ORACLE_HOME/srvm/lib
 $ make -f ins_srvm.mk iosdbagrp

 $ srvctl add database -d ERPDBA -o /erp_base/app/11.2.0 -p '+DATA/spfileERPDBA.ora' -c RAC -a EBS
 $ srvctl add instance -d ERPDBA -i ERPDBA1 -n nizam-rac1
 $ srvctl add instance -d ERPDBA -i ERPDBA2 -n nizam-rac2

 $ srvctl start database -d ERPDBA
 $ srvctl status database -d ERPDBA
 Instance ERPDBA1 is running on node nizam-rac1
 Instance ERPDBA2 is running on node nizam-rac2
