prvf 5300 failed to retrieve active version for crs on this node

We tried to install  11.2.0.2 oracle software version.When we ran the runInstaller it throws the
 prvf 5300 failed to retrieve active version for crs on this node error.
 11.2.0.3 ASM Grid already installed in server also the server has 11.1.0.7 version software and 11.1.0.7 databases using 11.2.0.3 ASM

Solution:-

1. Backup the files /etc/ocr.loc or /etc/oracle/ocr.loc and /etc/oracle/olr.loc, then rename them to some other names.
2. Retry the standalone (non-RAC) Database 11.2.0.2 installation.
3. After installation completed; restore/rename the backed up files to ocr.loc and olr.loc files in the /etc/ocr.loc or /etc/oracle/ocr.loc and /etc/oracle/olr.loc

Note:-
--No need to shutdown the existing databases and ASM while performing this operations.
--In some environment ocr.loc file is located in  /etc/ocr.loc or /etc/oracle/ocr.loc. It depends on the Operating System.

Problem we have faced at our environment:-


After renamed both the files we are unable to log in to existing databases available in that server.
We have not restored the original files ocr.loc and olr.loc files in original location after completing 11.2.0.2 oracle software installation ,so we have faced the below error;  
Note:- We came to know ; These 2 files are needed if we are using a grid,.
after renamed both the files to original name; we are able to log in to existing databases available in that server.

see the below error message:-
SQL> select status from v$datafile;
select status from v$datafile

ERROR at line 1:
ORA-00204: error in reading (block 1, # blocks 1) of control file
ORA-00202: control file: '+DG1/eagleb/controlfile/current.716.751453263'
ORA-15081: failed to submit an I/O operation to a disk

we have renamed the files ocr.loc and olr.loc again from backup. and the problem got resolved.
   
These 2 files are needed if we are using a grid,.

I really thank my colleague Krishna; We worked together in this problem.
