Workaround.

Its a Bug below is the workaround –

Undefined subroutine &main::read_file called at /u01/oracle/product/11.2.0/grid/crs/install/crspatch.pm line 86.

 Take a backup of the file <GridHome>/crs/install/crsconfig_lib.pm

cd /u01/oracle/product/11.2.0/grid/crs/install

 cp crsconfig_lib.pm crsconfig_lib.pm.bak

Make the following change in that file crsconfig_lib.pm

From
     my @exp_func = qw(check_CRSConfig validate_olrconfig validateOCR
To
     my @exp_func = qw(check_CRSConfig validate_olrconfig validateOCR read_file

Now lock and relink the GI HOME as root user….

root@ # diff crsconfig_lib.pm crsconfig_lib.pm_bkp

<   my @exp_func = qw(check_CRSConfig validate_olrconfig validateOCR read_file

---

>   my @exp_func = qw(check_CRSConfig validate_olrconfig validateOCR
