Aircraft; Procedure
Ferry flight. Previous to flight I knew maintenance was determining whether the flight would be flown with the gear down and locked or gear up. Due to icing conditions we had to go gear up. Ferry permit was adjusted and we left. Once airborne the gear would not raise. While the CA (Captain) was hand flying; the FO (First Officer) used the solenoid switch to raise the handle. Gear did nothing; but soon followed a gear disagree warning message; WOW (Weight On Wheels) Output caution message; Nose Wheel Steering Inop Caution Message; and a Prox Sys 1 Fault status message. We ran the QRH procedures; which basically had us land with no nose wheel steering and unpressurized the airplane as well as manually deploy the spoilers on landing. We did [notify ATC]. Asked for a tug to be available to tow from the runway; also asked for them to verify gear down on final (both Tower and an aircraft over the approach end verified for us they were down) and landed without further incident. After coming to a stop; I tried to cycle the nose wheel steering switch in hopes of being able to move ourselves off the runway with no luck. Tug came out. We did the procedure for two engines shut down and prepared to finish the WOW checklist prior to power down. Called maintenance upon parking and they told us we did not need to comply with the WOW checklist that had us pulling a bunch of circuit breakers to prevent the ADG from deploying since the WOW message disappeared and the prox sys message disappeared. Called [Operations] and scheduling for further guidance.
CRJ-900 Captain reported the landing gear failure to retract was accompanied by several caution messages.
