The kfed is an undocumented utility located at $ORACLE_HOME/bin that can be used to edit the contents of ASM blocks and return information about ASM.
The kfed does not depend on the mount state of an ASM instance or ASM disk group, so it can be used with ASM instance down and on a disk group that does not mount. KFED can also be used on ASM disks with corrupt ASM metadata.
unable to open file '<file_path_and_name>' corresponds to ORA-15031
