By default, the opposite side is anode (A). You may need a magnifying glass to make sure though, because other diodes can have quite similar markings. You can usually tell by looking at the markings on the diode, but if they've worn off or don't exist you can use a multimeter to test the diode. These handling difficulties prompted development of alternative SMT packages for common MELF components (like diodes) where the power handling capability needed to be similar to MELF components (superior to low-power 0805/0603, etc. To address this, manufacturers use a color banding system like that of leaded resistors, well-suited to the curved surface of MELF resistors.
