What is wrong at my HP-UX box?

My guess is that nothing is wrong with it.

ls -ld /t_dk1 /t_dk2

mount

I can "cd /lib", too, but that doesn't mean
that "/lib" is a mount point or file system.

As Steven says, there is likely nothing wrong with it. Find the real mount point by:
$ bdf /t_dk1 /t_dk2

Hi,

if the two mentioned mount points exist in /etc/fstab the described behavior could mean that no disks are presently mounted on these mount points. Try this:

# cd /t_dk1
# bdf .

to see which file system is used; probably the / file system.

Then perform
# mount -a
If something new is mounted, try the above mentioned commands again.

regards,
John K.

please check your /etc/fstab file. is /t_dk1 and /t_dk2 already at that file.

if not please add. when server reboot, the server will be looking /ec/fstab. so if you not mention, it will be not mount.

thanks
Freddy

Finally, i use "bdf /t_dk1" and "bdf /t_dk2" and found that
>bdf /t_dk1
/dev/vg00/lvo13
>bdf /t_dk2
/dev/vg00/lvo13

both of them are mounted into the same logical volume.

So, i use "fuser -k /t_dk1" and then "umount /t_dk1", and then mount into the new mount point.

Now, i can bdf

You can add it manually to /etc/fstab.

Yes, one or the other.

Adding data to /etc/fstab will get your file
system mounted when someone does "mount -a".
Mounting a file system adds nothing to
/etc/fstab.

man 1m mount

and also when you reboot your system, if you dont add a line in fstab, everytime you have to manual mount.
