Single user mode on ia64

How does one boot in single user mode on an ia64?

Thanks in advnace,

Re: Single user mode on ia64

Basically the same way as PA-RISC systems. Interrupt the boot process (by default there is a 10 second period where you have the option to intterrupt it), and enter 'hpux -is' at the prompt. That's it.

Re: Single user mode on ia64

Actually, the procedure is a bit different from PA systems. Essentially, instead of
'hpux -is /stand/vmunix' you type
'boot vmunix -is' to get to single user mode.
Screen log below...

After rebooting, interrupt
the boot sequence:

Please select a boot option

Re: Single user mode on ia64

Hi All, 


after you switched diff drives like fs0: or fs2: .. you have to give it full path to boot in single user mode.  Below is step by step with typos to test commands ... or maybe fat fingers! ..
