Configure CTE and create a guarded Oracle ASMFD

To configure CTE and create a Guarded Oracle ASMFD:

1. Create a raw device disk, for example:

    /dev/sdc
   

2. Partition the targeted raw device, for example:

    /dev/sdc1
   

3. Guard the partitioned raw device, that you just created, using CTE.

4. Create an ASMFD disk on the guarded partitioned raw device, type:

    $GRID_HOME/bin asmcmd afd_label '<disk_label>' '<guarded_raw_partition>'
   

   Example:

    $GRID_HOME/bin asmcmd afd_label 'DISK1' '/dev/secvm/dev/sdc1'
   

5. Verify that the new disk was created, type:

    $GRID_HOME/bin asmcmd afd_lsdsk
   

   The disk should display in the list of disks, similar to the following:

   Label  Filtering   Path
   ================================================================================
   DISK1  ENABLED   /dev/secvm/dev/sdc1
   

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

7. Now you can use the Oracle Grid ASM Configuration Assistant GUI to create the targeted guarded ASMFD disk group on the above created guarded ASMFD disk, DISK1. See the Oracle GRID documentation for more information.
