The total and free space is calculated on the redundancy of the Disk Group. The calculation is complicated when a Disk Group has more then the required number of Failure Groups. The check expects 2 for NORMAL and 3 for HIGH redundancy without and 3 or 5 with voting files. The size of every Failure Group of a Disk Group must be the same, which is a recommendation from Oracle. Otherwise the calculation is wrong.

The expected number of Failure Groups for a Disk Groups is the default for nearly every Oracle installation.

This fix changes nothing when EXTERNAL redundancy is used.
