Enable Oracle ASMFD for CTE

To enable Oracle ASMFD:

1. Log in as the root user and stop the Oracle Grid Infrastructure for a standalone server, type:

   $GRID_HOME/bin/crsctl stop has
   

2. Configure Disk Discovery for AFD. Modify the following files by adding the content of /dev/secvm/dev/sd* to the OS files in /etc/oracleafd.conf and /etc/afd.conf with aft_filtering enabled, type:

   1.  cat /etc/afd.conf
      afd_diskstring='/dev/sd*,/dev/secvm/dev/sd*'
      afd_filtering=enable
      

   2.  cat /etc/oracleafd.conf
      afd_diskstring='/dev/sd*,/dev/secvm/dev/sd*'
      afd_filtering=enable
      

   3. To prevent the file from changing back to afd_diskstring='/dev/sd*' make it read only, type:

      # !yaml
      chmod 444 /etc/oracleafd.conf /etc/afd.conf
      

3. Restart ACFS before proceeding, type:

    acfsload stop
    acfsload start
   

4. Restart the Oracle Grid Infrastructure, type:

   $GRID_HOME/bin/crsctl start has
   

5. Verify that /dev/secvm/dev/sd* is part of the SQL output and the state is enabled as a grid, type:

   SELECT SYS_CONTEXT('SYS_ASMFD_PROPERTIES', 'AFD_DISKSTRING') FROM DUAL;
   

   Expected Response

   SYS_CONTEXT('SYS_ASMFD_PROPERTIES','AFD_DISKSTRING')                
   --------------------------------------------------------------------------------
   /dev/sd*,/dev/secvm/dev/sd*
   

   If using Oracle RAC (Real Application Clusters), repeat the previous steps for all of the nodes in the related RAC cluster.
