Booting into Single User Mode

Ted McLean — Thu, 18 Mar 2004 12:28:32 GMT

Hello,

One final question, how do I boot into single user mode? On an earlier post someone instructed me to use teh shutdown command "shutdown -y -r 0" and then cancel the boot process when it was reloading. After that I was supposed to select the boot primary option and then the instructions said that I was supposed to answer "yes" when a question about SLI came up but when I tell it to boot primary it just resumes booting as if I hadn't canceled the process before hand...What am I doing wrong?

You interrupt the boot process then
BOOT PRIMARY
Interact with ISL(or IPL)? Y
hpux -is

You will then boot in single-user and be logged in as root.

when you tell it to boot primary, it should give you a prompt to interact with the ISL. You should reply 'y' to this.

once the ISL> prompt is there , use this command to boot to single user mode:
hpux -is

You should be able to abort the boot sequence when prompted. Most HP9000's give you 10 seconds to do so, so keep your eyes peeled.

Once aborted, you can do the following:

boot pri

Here it will prompt you "Interact with IPL" or something like that. You must answer Yes here.

Then you will arrive at another prompt (The IPL prompt) where you do:

hpux -is

and the machine should boot into single user mode.

After answering 'yes' to the boot primary and ISL prompts you should type in
'hpux -is' (no quotes), that puts you in single user mode.

I tried following those steps the problem occues when I type

"Boot Pri"

When I do so I don't get the command that asks me about SLI but instead the machine continues to boot up...Any ideas?

Thanks
