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:

$ $ORACLE_HOME/bin/asmcmd lsdg

1

$ $ORACLE_HOME/bin/asmcmd lsdg
List the associated disks:

$ $ORACLE_HOME/bin/asmcmd lsdsk -G diskgroup

1

$ $ORACLE_HOME/bin/asmcmd lsdsk -G diskgroup
Check if Oracle ASM is active:

$ $ORACLE_HOME/bin/srvctl status asm

1

$ $ORACLE_HOME/bin/srvctl status asm
Stop the databases and dismount the disk group on all nodes:

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

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:

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

1

$ $ORACLE_HOME/bin/asmcmd afd_label label disk_path --migrate
Scan the disks on all Hub nodes:

$ $ORACLE_HOME/bin/asmcmd afd_scan

1

$ $ORACLE_HOME/bin/asmcmd afd_scan
Start the databases and mount the disk group on all nodes:

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