HP-UX 9 - booting in single user mode

[Matthias Oswald]

Hello,
I'm trying to boot a HP-UX 9 workstation in single user mode.
AT the ISL propmt, I type "hpux -iS",
but it jumps back to the ISL prompt.
Typing just "hpux" boots automatically ..

Thanks,
Matthias.

Hi Matthias,

Have you tried "hpux -iS /hp-ux" ?

Hello,

Try as ISL >hpux -is /stand/vmunix
or ISL > hpux -is /hp-ux

Matthias,
I know it should not really matter, but have you tried in lower case i.e. hpux -is

If that does not work, define the kernel you are booting after the -is.

If you are re-booting due to kernel rebuild,
perhaps use your earlier kernel

If that also does not work boot into maintenance hpux -lm

Finally use the recovery CD

hi matthias,

in the worst case, you may also wish to boot normally and then issue:

init -s

This should bring you to the single-user environment

hope this helps too!

kind regards

Its casting my mind back about 10 years, but I *think* that in v9 you may have had to put the full hardware path in, something like:
hpux -iS (8.2.1.0;0)/hpux

At least you could try this one:
hpux -iS (;0)/hpux

I cannot clearly remember where the kernel was located and what the kernel filename was back in v9. I am sure you know that yourself, but you had to put the location of the kernel to boot from at the end of the line.

The correct syntax would be:
hpux -is (;0)/hp-ux

or from the backup kernel
hpux -is (;0)/SYSBCKUP

If you use -iS (capital s) that was for installing the system (if I recall correctly from that far back)

[Lolupee]

as indicated by melvyn. The correct syntax is hpux -is(;0)/hpux or if you have the old kernel

hpux -is(;0)/hpux.prev or old as the case amy be

[Lolupee]

Yes, the backup is SYSBCKUP and not hpux.prev

Please, do not forget the SYSBCKUP is without "A"
