Force mount with HPUX 11.00 when Block Read Error

Hello,

as a consequence of a recent blackout one logical volume reports a
block that can't be read. This error can't be fixed by fsck. Running
fsck I am informed that Block 8926464 can't be read. The filesystem is
marked as not clean...

Asking Google I found (of course) that this is not the first time,
something like this has happened. But all the answers I was able to
find suggest to force the mounting of the involved filesystem. I can't
find a -f switch in HPUX 11.00, so I can't mount the filesystem. All I
can get is:

kelain [~]# mount -r /dev/vg01/lvol1 /users
mount: /dev/vg01/lvol1 needs to be fsck'ed before mounting
mount: warning: if device /dev/vg01/lvol1 is mounted to another system
then do not run fsck

Any hints on how the data in this volume can be saved would be greatly
appreciated!

Thanks in advance

Hinnerk
