ORA-15221: ASM operation requires compatible.asm of string or higher

Hi,

Sometimes you can get  “ORA-15221: ASM operation requires compatible.asm of string or higher  ” error.

 

Details of error are as follows.

ORA-15221: ASM operation requires compatible.asm of string or higher

Cause: The ASM operation specified requires a higher disk group attribute value for compatible.asm.

Action: Set the disk group attribute compatible.asm to or above the requested version.

ORA-15221: ASM operation requires compatible.asm of 12.1.0.0.0 or higher

 

 

Check the database and ASM Compatibility.

SQL> select group_number, name,compatibility, database_compatibility from v$asm_diskgroup;
 
GROUP_NUMBER NAME  COMPATIBILITY DATABASE_COMPATIBILITY
------------ ----- ------------- -------------------------
 1           DATAC1  11.2.0.0.0    11.2.0.0.0
 2           RECOC1  11.2.0.0.0    11.2.0.0.0

 

 

 

Change compatibility and database compatibility attributes of disk group as follows.

 

SQL> alter diskgroup DATAC1 set attribute 'compatible.asm'='12.1.0.0.0';

Diskgroup altered.

SQL> alter diskgroup RECOC1 set attribute 'compatible.asm'='12.1.0.0.0';

Diskgroup altered.

SQL> alter diskgroup DATAC1 set attribute 'compatible.rdbms'='12.1.0.0.0';

Diskgroup altered.

SQL> alter diskgroup RECOC1 set attribute 'compatible.rdbms'='12.1.0.0.0';
Diskgroup altered.

 

Check disk groups attributes again, they are changed.

SQL> select group_number, name,compatibility, database_compatibility from v$asm_diskgroup;
 
GROUP_NUMBER NAME COMPATIBILITY DATABASE_COMPATIBILITY
------------ ---- ------------- -------------------------
 1           DATA 12.1.0.0.0    12.1.0.0.0 
 2           FRA  12.1.0.0.0    12.1.0.0.0

 

Problem has been solved.
