root problem

[cys691018]

My root(hp-unxi 11.xx) has no sufficient space to boot for my mistake. Can anyone help me ?
I can't enter hp-unix to delete useless files in root .

login as single user mode and extend the filesystems

It looks like your root filesystem is full, and you cant login to the box.

-If you have open session you can do cleanup as it is not allowing any other user to login,

- If you have rebooted the box, reboot to single user mode:
in Itanium : Iterupt boot sequence:

from HPUX> boot vmunix -is

You will get single user mode,
# vgchange -a y vg00

Mount the / , /usr/ , /var , /opt /home , do necesseery cleanup of / , where you thing the unwanted files are.

Reboot the box and check.

Hth,
Raj.

Hi

Note to you and 1st comment posted by David Williams regarding extending the root filesystem.

No, you can not do this. The first three logical volumes of a boot disk are contiguous (* sequential *) and MUST remain that way. Extending one would make it random and unbootable.
