Back in my VSE days (DOS/VSE) we created a stand alone IPL tape weekly. I managed to screw up an IPL volume and we needed the tape and the procedure. At the time we hadn't a clue how to IPL from tape (yes!).
Fortunately, the systems programmer who set up the procedure was down the road and he jumped in a taxi and rescued the day. I don't think anything disk resident was needed to get us going to the point where we could start things like CICS, which came from disk.
