Boot into HPUX L2000

root's picture

The other day I got into the situation where I had to boot up a hp-ux OS from L2000 console. For whatever reason, the OS was down and all available option was the console.
Even if the internet is full of tutorials and documentation, it was a bit difficult to find a quick way to start the system.

On the following I will show you how I did it:

some@hp>telnet 10.10.10.10

[Read only - use ^Ecf for console write access.]

[size=15]At this point, you have to type SHIFT+Ctrl+E c f in order to get write access to the console.
The prompt should change to:

[bumped user - ]

[size=15]Obviously, typing help got me nice information:[/size]

[size=15]Of course, this menu was totally unfriendly, every obvious command giving error (e.g. help, exit, quit :D). Googling a little I have found [urlnew=http://www.unixhub.com/docs/hpux/hpux_boot.html]this website[/urlnew] which got me to the right track. There is a lot of useful information there and I am welcome you to read it. So, I proceed with one command that I would never guess, [abbr=secondary system loader]hpux[/abbr]:
