Server starting in single user mode only?

Irfan Ahmed_1 — Tue, 30 Nov 2004 09:52:22 GMT

Hi all,
My server is starting in single user mode everytime I restart. Also I am not able to use most of the commands. If I do cd /directory & then again inside that
cd /directory it is not working.
What should I do?

Thanks

Boot into single user mode. Do a mountall
Now do
mkboot -a "hpux -lq (;0)/stand/vmunix" /dev/dsk/cxtxdx

User the real boot disk.
lvlnboot -R
lvlnboot -v

Reboot. Now it should boot into multiuser mode.

Hello,

try to change your AUTO file in boot LIF area like this:

# mkboot -a "hpux /stand/vmunix" /dev/rdsk/cXtZdY
where /dev/rdsk/cXtZdY is your boot disk

it is better to make an ignite tape before...

Hi Irfan

Please check the entries of /etc/inittab

Check for the entry
initdefault

It may be pointing to single user mode.
By default it will be run level 3 with NFS Server run option.

Just a thought

Hi,

Could you please try to find the reason of such a behaviour ?
First, stop the boot and answer "Y" on the question whether you want IPL.
If the boot fail, you have to edit mkboot as:
mkboot -a "hpux /stand/vmunix" /dev/rdsk/XX
after boot completion
If the boot from the primary disk is OK, give the command:
hpux -is
This will boot the computer into single-user mode.
Run
fsck -y
mount -a
and look at /etc/inittab file
If initdefault entry is not 3, update it as following:
init:3:initdefault:
and run
init 3
Look at error messages. If everything is OK, reboot the computer, it must go level 3

Hi,
What kind of server is it? Did you change any hardware lately?
If it boots single user, you must have some error message on the console explaining whats going on unless someone changed the initdefault but since you seem to have a strange behaviour I would look for error message, knowing the type of box and OS would help here...

All the best

Are you seeing errors on the console during boot?
