Migrating Oracle ASM Disk Groups without Oracle Cluster Registry or Voting Files

To migrate Oracle ASM disk groups without Oracle Cluster Registry (OCR) or voting files to Oracle ASMFD:

  1. Log in as the Oracle Grid Infrastructure owner on any node to run the commands in this procedure.

  2. List the existing disk groups:

    $ $ORACLE_HOME/bin/asmcmd lsdg

  3. List the associated disks:

    $ $ORACLE_HOME/bin/asmcmd lsdsk -G diskgroup

  4. Check if Oracle ASM is active:

    $ $ORACLE_HOME/bin/srvctl status asm

  5. Stop the databases and dismount the disk group on all nodes:

    $ $ORACLE_HOME/bin/srvctl stop diskgroup -diskgroup diskgroup -f

  6. Label all existing disks in the disk group by running the following command for each disk on a Hub node:

    $ $ORACLE_HOME/bin/asmcmd afd_label label disk_path --migrate

  7. Scan the disks on all Hub nodes:

    $ $ORACLE_HOME/bin/asmcmd afd_scan

  8. Start the databases and mount the disk group on all nodes:

    $ $ORACLE_HOME/bin/srvctl start diskgroup -diskgroup diskgroup
