Deconfiguring Oracle ASM Filter Driver

If Oracle ASM Filter Driver (Oracle ASMFD) is installed but you do not use it for device path persistence, then deconfigure Oracle ASMFD.

  1. Log in as root.
  2. Set the environment variable $ORACLE_BASE to a temporary location.
    # export ORACLE_BASE=/tmp
  3. Shut down the Oracle Clusterware stack on the local node.
    # crsctl stop crs
  4. Stop Oracle ACFS kernel modules.
    # $ORACLE_HOME/bin/acfsload stop
  5. Deconfigure Oracle ASMFD filtering.
    # $ORACLE_HOME/bin/asmcmd afd_deconfigure
  6. Start Oracle ACFS kernel modules.
    # $ORACLE_HOME/bin/acfsload start

    Note:

    This step is required even if you do not use Oracle ACFS.
  7. Start the Oracle Clusterware stack on the local node.
    # crsctl start crs
  8. Repeat steps 1 through 7 on all other cluster nodes.

Note:

Starting with Oracle Database 23ai, Oracle ASMFD is desupported. When upgrading from Oracle Grid Infrastructure 19c to 23ai, you must ensure that the Oracle ASM devices are owned by the asmdba group. For more information about Oracle ASM device user and group ownership requirements, refer to Configuring Device Persistence Manually for Oracle ASM.
