The G flat minor chord is enharmonically the same as the F minor chord. The Gbm chord actually contains a B double flat (Bbb). This is because the Gb Major chord contains Bb as its 3rd. Therefore, when we lower the 3rd by another semitone, it becomes Bbb (B double flat), which is the same note as A.
The Bbb can technically be played on an open string (5th string), but because it is so low, it sounds muddy and is impractical. Therefore, Gbm is not practical as an open chord. Instead, the chord is usually played as a bar chord, on the 2nd fret (root 6) or 9th fret (root 5).
