I made both changes. 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 Cell 917-903-0102 -----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.
