Migrating Oracle ASM Disk Groups in an Oracle Grid Infrastructure Standalone (Oracle Restart) Environment

To migrate your existing Oracle ASM disk groups to Oracle ASM Filter Driver in an Oracle Grid Infrastructure standalone environment, perform the following steps:

Log in as the Oracle Grid Infrastructure standalone server owner to run the steps in this procedure.
List the existing disk groups:
```
$ $ORACLE_HOME/bin/asmcmd lsdg 
```

List the existing disks:

$ $ORACLE_HOME/bin/asmcmd lsdsk -G diskgroup_name

Check if the status of your Oracle ASM instance is active:
```
$ $ORACLE_HOME/bin/srvctl status asm
```

Stop all the databases and dismount all disk groups. For each database, run the following commands:

$ $ORACLE_HOME/bin/srvctl stop database -db db_unique_name

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

Label all existing disks in the disk group by running the following command for each disk:
```
$ $ORACLE_HOME/bin/asmcmd afd_label label disk_path --migrate
```
Rescan the disks:
```
$ $ORACLE_HOME/bin/asmcmd afd_scan
```

Start the database and mount the disk group:

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