Add filegroup fails with ORA-15067: command or option incompatible with diskgroup redundancy

Problem:

I was trying to add filegroup to the FRA diskgroup:

SQL> alter diskgroup FRA add filegroup high_filegroup database orcl set ‘datafile.redundancy’ = ‘HIGH’;

Error:

ORA-15067: command or option incompatible with diskgroup redundancy

Troubleshooting:

Checking diskgroup type:

SQL> select name,type,compatibility,database_compatibility from v$asm_diskgroup where name=’FRA’;

NAME      TYPE   COMPATIBILITY    DATABASE_COMPATIBILITY
————- —— ————————– ————————————————————
FRA        NORMAL 18.0.0.0.0    12.2.0.1.0

Solution:

Change diskgroup type to FLEX:

SQL> alter diskgroup FRA convert redundancy to flex;
Diskgroup altered.

Check that type was changed:

SQL> select name,type,compatibility,database_compatibility from v$asm_diskgroup where name=’FRA’;

NAME      TYPE   COMPATIBILITY    DATABASE_COMPATIBILITY
————- —— ————————– ————————————————————
FRA        FLEX   18.0.0.0.0    12.2.0.1.0

Adding filegroup succeeds:

SQL> alter diskgroup FRA add filegroup high_filegroup database orcl set ‘datafile.redundancy’ = ‘HIGH’;
Diskgroup altered.
