Result was that some disk groups were not mounted:

SQL> select NAME, STATE, COMPATIBILITY from v$asm_diskgroup;

NAME  STATE 		COMPATIBILITY
----- ------------ ---------------
REDO  MOUNTED     	19.0.0.0.0
DATA  DISMOUNTED  	0.0.0.0.0
FRA   DISMOUNTED  	0.0.0.0.0

When trying to mount it:

SQL> alter diskgroup FRA mount;
alter diskgroup FRA mount
*
ERROR at line 1:
ORA-15032: not all alterations performed
ORA-59303: The attribute compatible.asm (10.1.0.0.0) of the
