- My machine got into a state in which it would execute
- shutdown -h -y now
- during the startup, like it was the last thing in /etc/rc.
-
- Thus, my console would eventually tell me that it was ok to cycle
- power. If I cycled power, it would reboot and execute shutdown -h
- again.
-
- The only way I could get control back was to boot off another HP on
- the lan, which involved rebuilding the root disk. That was not a
- disaster since I had backups of my /users and /usr/local trees.
-
- But if I could have coaxed HP-UX to boot single user I might have been
- able to fix the problem without rebuilding.
-
- I checked laserrom but the only way I was able to find was to do
- shutdown without the -r or the -h flags. (I actually tried to do this
- by telneting to my machine from a remote machine during the 10-20
- seconds I had between activation of the networking daemons and the
- shutdown -h, but I was never fast enough).
-
- So, my question is, is there any way during a normal cold boot to
- force the OS (HP-UX 8.07 in this case) into single-user mode?
