Sierrah is a spelling of Sierra, pronounced the same way, so it shares Sierra's meaning and origin.
Sierra is a Spanish word name. In Spanish, sierra means a saw and, from the jagged look of a saw blade, a range of mountains; the Real Academia Española and the American Heritage Dictionary both trace it to Latin serra, saw.
