To migrate Oracle ASM disk groups without Oracle Cluster Registry (OCR) or voting files to Oracle ASMFD:
- Log in as the Oracle Grid Infrastructure owner on any node to run the commands in this procedure.
- List the existing disk groups:
1$ $ORACLE_HOME/bin/asmcmd lsdg
- List the associated disks:
1$ $ORACLE_HOME/bin/asmcmd lsdsk -G diskgroup
- Check if Oracle ASM is active:
1$ $ORACLE_HOME/bin/srvctl status asm
- Stop the databases and dismount the disk group on all nodes:
1$ $ORACLE_HOME/bin/srvctl stop diskgroup -diskgroup diskgroup -f
- Label all existing disks in the disk group by running the following command for each disk on a Hub node:
1$ $ORACLE_HOME/bin/asmcmd afd_label label disk_path --migrate
- Scan the disks on all Hub nodes:
1$ $ORACLE_HOME/bin/asmcmd afd_scan
- Start the databases and mount the disk group on all nodes:
1$ $ORACLE_HOME/bin/srvctl start diskgroup -diskgroup diskgroup
