The kfed is an undocumented utility located at $ORACLE_HOME/bin that can be used to support ASM deployments.
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.
