Rx2600 single user mode

[Achilles_2]

hi all,

I have rx2600 server and now I want to extend the size of /opt directory. I haven't any idea to boot to single user mode in order to unmount the /opt? Do you know the procdures?

Thanks
Alex

Hi,

you select the HP-UX at boot option
then intrrupt the prompt

it will come to HPUX>hpux -is

Hi Alex

first do a controlled shutdown of the server

/etc/shutdown -hy now

switch the system back on and press and key on the keyboard in the first 10 seconds to interrupt the boot sequence.

now type "bo"

the system will ask if you wish to interct with IPL answer "YES"

now type hpux -is

this will fetch the system up in single user mode with a hash prompt. You will now be able to extend the /opt filesystem

hi alex,

here goes:

u may do a shutdown but most importantly, u must break the 10 seconds before u can proceed to single user mode via:

after breaking to PDC Menu --> bo pri

ISL> hpux -is

# mount /usr
if /dev/vg00/lvol6 is the logical volume for /opt
# /usr/sbin/lvextend -L 1024 /dev/vg00/lvol6
# /usr/sbin/extendfs -F vxfs /dev/vg00/rlvol6
# lvdisplay /dev/vg00/lvol6
# mount /opt
# bdf
to check if the size is correct.

regards.

The replies from the other responders
contain good info. However, the rx2600
is an Itanium machine so the boot process
is a little bit different. The terms
PDC, ISL and IPL refer to the PA-RISC boot
process.

To get into single user mode on Itanium,
wait until you see the Boot Manager Menu.
This will list several options like "Boot
HP-UX" and "Start EFI Shell". I believe
you have 10 seconds to select an option.
Using the arrow keys, highlight "Boot HP-UX"
and then hit Enter. Then you have 10 more
seconds to hit any key to stop autoboot.
Then you can type "hpux -is".

Hi again,

intrrupt the HP-UX at boot time.

use the boot -is option.
It will work.

Thanx
