Disaster Recovery Plan. Make sure you formulate one, and have it in place as corporate policy for next time.
I worked for a 1000 seat facility with an AS-400 system. There were two of them (second one was for backup), and not only that, we had an off-site service that had a third one in-house just in case the worst happened. Backup tapes were delivered to the off-site location every night. There was a guy who worked in the department whose sole job was to ensure that we had a continually-improved disaster recovery plan - he even ran worst-case scenario simulations. Everyon was aware of what they were supposed to do in the event of our server room blowing to kingdom come or whatever.
IBM and Sungard both have great disaster recovery programs - we used them both in case one of THEM had a disaster to recover from, in the midst of our disaster.
