Our procedures don't say much.
If any main gear is stuck, we will get a message saying "Gear Disagree". If the lever is down, this means that not all gear were successfully extended. The procedure is to use the Alternate Gear Extend Switch and see if that works. If not, then we simply land on what we have. Our checklist says not to try and taxi the airplane or use the tiller. Braking action will also be affected.
If both body gear are not out, then there is a danger of the aircraft tipping onto it's tail, in which case we are not to use the slides at door one for evacuation.

It did could be 20 yrs ago SFO Pan Am I think. Took of to low cought the runway lights on the way out ripped up the belly and body gear landed on the wing gear after she rolled to a stop she sat back on her tail. all the fwd escape slides were useless. The nose was way of the ground.

YES, you're right, IFIX747's......
On July 30, 1971, a Pan Am 741 hit the light structure at SFO and returned with several useless wheels. The pilot used reverse thrust on just one engine to compensate.
The above episode made an excellent chapter in a book I recently received about non-fatal air crashes.
Interestly (for anybody who might care about such co-incidences) .... The Pan Am SFO problem occurred on the exact same day as another major airline crash. ......
>> Morioka, Japan, July 30 1971 - 162 dead
All Nippon Airways B-727-281 collides with an F-86.
This was the 44th worst air crash (by deaths) in history.

A United Airlines Boeing 747-422 landed at Los Angeles International with a hydraulic system failure.
The body gear was fully retracted, the wing gear was extended and the nose gear doors were open with no gear extension.
After doing a touch and go to try shake the gear down the aircraft landed on the wing gear alone and settled onto the nose gear doors.

just like Avi said. It also depends on your load factor too. How heavy is your aircraft? Many passengers? Cargo? Fuel? In the best case it would be near the end of the flight when you lower the gear (meaning you've used-up the fuel from the flight you just did, therefore you weigh much lighter too), making it easier for the remaining gear to support the aircraft. I don't wish this to anyone though.
