Expected results:
1. It should keep the same output before and after register to rhevm in rhevh. So it should not list the single path after register to rhevm also.

This is a side effect of bug 1173290. sda, which is used for booting was not claimed, because it is already in use, so there should be not functional impact on the core RHEV-H functionality.
