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.

Re: Problem using IUCVCONN in single user mode
Hey Joe, You are correct, I do not have S in the start line of my upstart job. You can always try your upstart job the way you had it, but I vaguely remember testing a similar upstart config a couple years ago and it not working as I thought it would. The strange thing that will occur when you have a failed filesystem check is your output just goes away on your 3270 as it gets directed to the iucv console. I don't like this solution, but I put in an echo statement that is directed to /dev/ttyS0 in /etc/rc.d/rc.sysinit so we could see the failure in 3270 and know to switch over to IUCV.

After boot hvc0 console kept logging on root and then the standard logon prompt. Seems 2 processes are on hvc0 console. Both from /etc/init/tty.conf and /etc/init/ttyH0.conf I removed from tty.conf: --autologin root but would not accept root id/password. I see I am on console: # who root console 2014-01-24 14:41 /etc/securetty has hvc0 hvc1 listed tty.conf: stop on runlevel [S016] respawn instance $TTY exec /sbin/mingetty $TTY --autologin root ttyH0.conf: start on stopped rc RUNLEVEL=[2345] stop on runlevel [S016] respawn exec /sbin/agetty -L 9600 hvc0 xterm Thanks Joe Joseph Vitale Technology Services Group Mainframe Operating Systems 95 Christopher Columbus Drive Floor 14 Jersey City, N.J. 07302 Work 201-395-1509 Cell917-903-0102 -Original Message- From: Linux on 390 Port [mailto:LINUX-390@VM.MARIST.EDU] On Behalf Of Brent Kincer Sent: Friday, January 24, 2014 12:54 PM To: LINUX-390@VM.MARIST.EDU 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.

Problem using IUCVCONN in single user mode
Hello, I notice when zLinux 6.2 drops into Single User mode at boot up say due to bad /etc/fstab, I cannot connect via iucvconn Guest lnxhvc0. The command just hangs. Appears /etc/init/ttyH0.conf is not run in single user mode. I logon as root to 3270 console and enter exec command from ttyH0.conf and hvc0 is usable. Any idea how to start this when entering Single user mode?
