Thanks, Peter, Rob THe devices 400 and 401 didn't show up on the output from lscss, even though they were listed in the VM USER DIR for the virrtual machine.
I took a tip from the other thread today and logged the machine off and on. That seems to have fixed the problem. The lscss shows the devices, and the device looks online. ifconfig shows the mpc0 interface, as it did before I upgraded. It looks good apart from some error messages about the kernel being tainted by LiS - but I think I've seen those before. According to chap. 11 of the device driver manual, I should have 3 directories: /sys/bus/ccwgroup/drivers/ctcmpc/0.0.400 /sys/bus/ccwgroup/drivers/0.0.400 and /sys/devices/ctcmpc/0.0.400 I have the first two, but not the last one. I don't even have a directory /sys/devices/ctcmpc: ------------------------------------------------------------------- LNXCCL:~ # ls /sys/devices css0 cu3088 iucv platform qeth system ------------------------------------------------------------------ I'll have to wait until Monday to try it with commserver, but at least I've got my interface back up. Looks like a good weekend.
