I'm trying to get a subchannel link going between an IBM Z-series box running VM and my 7204VXR router with a CPA card in it. I have the same setup working on our production box, but the new one won't work. I'm close, but no matter what we do, we cannot vary the path online in VM, and the subchannel display shows as offline. Pertinant info and displays are attached. Not sure what I'm missing. No matter what we try, the subchannel remains offline. I have this working to our production VM system on the same 7204 (different interface). Any ideas??
In which interface of 7204, you have connected or created this subchannel link? get the output of show interface intf type no at your router console. And also, while debugging, wht is the error message you receive?
Thanks for the reply... The interface is 4/0. Interface 1/0 is currently working on our production box. I haven't gotten any error messages from the debugging I've tried; I'm either not turning on the correct debugging, or as far as the 7204 is concerned there is no error. Sh interface output:
