How to Get Out of Single User Mode on HP-UX 11.0 K360

Laurie_2 — Tue, 21 May 2002 16:58:35 GMT

Hi All,

I was having some problem and I converted
to a TRUSTED SYSTEM and then converted Back
and a co-worker powered down my server.

Now the box keeps coming up in single user
mode and I can't get it into mult user mode.

When I reboot (shutdown -ry 0) it keeps coming
up in single user mode. I think a co-worker
was playing with the keyboard trying to fix
the system console which is not hook up right.

HELP... What command do I need to do to get out
of this stupit single user mode...

Laurie

Hi Laurie:

You need to investigate why it's going to single user mode ? Any warnings/errors ?

# init 3 - will take the system to run level 3 (multiuser mode)

Check system default init level in /etc/inittab

Hi Laurie:

The 'init' level is specified in the first line of '/etc/inittab'. It should look like:

init:3:initdefault:

This will bring the system to run-level 3.

You can manually move to a level with 'init [n]'.

Have a look at the man pages for 'inittab(4)' and for 'init(1M)'.

Regards!

Hi (again) Laurie:

Make sure you are trully stuck in single-user mode.

Do '/sbin/who -r' to determine the run level.

Are any of your filesystems mounted?

Regards!

Do a "/usr/sbin/setboot" to see what your boot parameters are set to. Interrupt the boot process and see what the AUTO file contains (if it had "hpux -is" that would be the culprit). That's all I can think of for now.

Good luck,
Pete

Hi Laurie

init 2 will take you to multiuser mode with network disabled and init3 will take you to the multiuser mode with netwrok enabled . That should be initdefault in /etc/inittab file.

Hi Laurie,

init 3
will take you into multi-user mode but before you do you need to see if you have any HW or other issues preventing atuoboot into multi.
Do a ctrl-b on the console then do a
ps
at the prompt - then
e
for errors
Look thru the list - you can sort if necessary & see if there any failures stopping the boot.
If you see nothing then
ma
back to main menu
and do
co
back to console & do the
init 3
When boot complete check the /etc/rc.log for any boot errors.

HTH,
Jeff

Control B doesn't break the console...

I typed init 3 and nothing is happening...so
I figured I would wait...

It's a K360...are you sure it's Control B to
get into the GSP?

I don't believe there is a GSP on the K class models.

Hi Laurie:

On K-class machines turn the KEY to the maintenance position. Then you should be able to do CTL_B ...

Laurie

type in co to get into the console mode , then try command like ls etc ? In you can see that then may be try mount -a and then init 2 or init 3.

Darrell Allen — Tue, 21 May 2002 17:36:34 GMT

Hi Laurie,

Any messages on the console?

Have you checked /etc/rc.log for clues?

Does mount or bdf show all the filesystems that should be mounted?

Does ioscan -fn show everything it should?

Have you any disks, etc that did not get powered up after the server was powered down? You need to always bring up peripherals before the CP.

I'm not sure but James makes me think: is the key in the correct (run?) position?

I stand corrected. Thanks JRF - I learn something new everyday around here.

Dooooh.....I forgot that you stated K in the title.
Absent minded today I guess.....
Sorry, Pete's right - no GSP on K.
You should get the CM> prompt from ctrl-B though where you can enter
rs
to restart the system if init 3 is doing nothing.

Sorry,
Jeff

Laurie_2 — Tue, 21 May 2002 17:46:35 GMT

OK i put the key back to service mode and
now I can do a CNTRL B.

However there is no PS otion.

Would RS be OK? I don't see a choice to look
at logs..RS seems the best choice.

It's still stuck in init 3 and nothing
is happening...

Pete Randall — Tue, 21 May 2002 17:53:16 GMT

Yeah, it's not a GSP but an "Integrated Access Port" and doesn't seem to offer much in the way of log access other than re-displaying the last 50 front panel status codes. At this point, do a reset.

Jeff Schussele — Tue, 21 May 2002 17:56:52 GMT

Hi Laurie,

Appears rs is your only choice at this point.
I'd follow the POST to see if there are any console warnings.

Jeff

James R. Ferguson — Tue, 21 May 2002 17:57:03 GMT

HI Laurie:

Do you have the /etc/rc.log checklist on the console? If so and if hung in a startup script do a CTL + pipe (|) to kill that script.
Have you changed a network component? DNS, NIS, NFS, etc?

Regards!

Laurie_2 — Tue, 21 May 2002 18:42:04 GMT

OK I'm in init 3 (single user ?) can't telnet
to the box.

I mounted all the file systems..but the informix files won't mount. I run fsck and it
complains.

I can do a basic bdf command and see the OS.

What do I do now?

By the way, I forgot to power off and on
the drives, so that is why the disks are
corrupted.

Laurie (I'm glad this is a test system but
I didn't expect it to break so soon)

Jeff Schussele — Tue, 21 May 2002 18:59:12 GMT

Did you use the
-o full
option in the fsck command?
If not try it again.
Also be sure to use the raw disk device
i.e. /dev/rdsk/cxtydz
in the command.

Rgds,
Jeff
