Brent,
Thank you very much for replying.
I think you pointed out my problem. "zipl.conf" specifies "console=hvc0"
1st, 2nd is "console=ttyS0" .
I was curious as to what was being run in that particular run mode. My
zipl.conf:
hvc_iucv=2 console=hvc0 console=ttyS0 hvc_iucv_allow=linux1,linuxtst
Can I confirm coding of your "upstart" job?
"start on stopped rc RUNLEVEL=[2345]" is correct, no "S"
start on stopped rc RUNLEVEL=[2345]
stop on runlevel [S016]
respawn
exec /sbin/agetty -L 9600 hvc0 xterm
Thanks again
Joe

Subject: Re: Problem using IUCVCONN in single user mode
To get our IUCV console working in Single User Mode, our upstart job looks like
this:
# This service maintains two agetty sessions on /dev/hvc0
start on stopped rc RUNLEVEL=[2345]
stop on runlevel [S016]
respawn
exec /sbin/agetty -L 9600 hvc0 xterm
I believe the /etc/rc.d/rc.sysinit should be directing console traffic in
runlevels S and 1 as long as your kernel parameters specify console=hvc0 AFTER
console=ttyS0. Order is important, the second console statement is your primary
console, and in runlevels S and 1, you can only have one console.
Hope this helps,
Brent
