Narrative:
Air carrier X TCASII equipped made an evasive maneuver up and to the right then advised responding to RA. Air carrier Y was also on visual approach behind and to the left approximately 1 mi for left runway. Air carrier X asked about traffic and was advised that only target was air carrier Y behind and to his left for parallel runway. Air carrier X maneuvered back to right runway requiring additional traffic calls.
