Robin, First of all, what did you do to get the tape IPL to work? Use a .tdf file, or something else?
I've never worked with a 2216, so take this with some skepticism. Yes, you need to define an LCS interface. Then, when you IPL your Linux system, you will need to tell it you have an LCS interface, not an ESCON one. I forget which flavor of Linux you're testing, but at some point you should be asked for chandev.conf parameters. You'll need to provide the appropriate device type and device numbers as documented in IBM's "Device Drivers and Installation Commands" book at http://www10.software.ibm.com/developerworks/opensource/linux390/docu/l390dd 09.pdf Chapter 12 will be a start, although most likely confusing. (I have to re-read various sections of that book several times whenever I try to do something new.) There should also be lots of discussion about LCS in the mailing list archives. The "escon0" designation it uses is simply the interface name, similar to eth0, eth1, etc. for Ethernet devices. When you tell the installer that you're using an LCS device, it will use a different name. (To be honest, I don't even remember what the interface name will be. I never had one to play with, so that bit of information didn't stick.) The system should tell you, in any case. If you want to get up to speed on Linux faster, install it on a spare PC or laptop laying around and play with it. When you don't need to get a network interface working right at the start, it's a little easier to learn stuff when you can just start exploring.
