System startup messages



We have an HP11.11 server that I rebooted last night. Do the messages that appear on the "console" when going into single-user mode / multi-user mode get written to a logfile anywhere?


Kind Regards,

Re: System startup messages

There are a couple of places to look for messages, once the system is up again:


For shut down messages -- /var/adm/syslog/OLDsyslog.log & /etc/rc.log.old


For start up messages -- /var/adm/syslog/syslog.log and /etc/rc.log

Always a good idea to boot from the console. That way if something unforeseen happens for example the boot hangs, you can see what happens.

Some of the console messages may still be in the MP logs.

Re: System startup messages

When you are in single user mode, all your normal logfiles do not exist. The filesystems such as /var are not mounted. You can see the console messages while you are in single user but you will have to save them in a file using dmesg, something like this:


    /sbin/dmesg > /dmesg.log


Otherwise, when you reboot, you will see the reboot console messages.


Now if what you really want is the list of commands given during single user mode, you can look at .sh_history, probably in /.sh_history or /root/.sh_history. There is no way to log what is displayed on the screen (in single user mode) except to use a PC and capture the text locally.
