Recently i have inserted a External hard disk in the HPUX server

created a new volume group through sam, and created PV, LV and mounted a directory name as /backup through command

Everything mounted successfully, and copied the data from server to hard disk.

Then again removed the hard disk and after this mouted folder backup was showing...

Removed the Volume group from sam, which took long time..

But when i execute bdf command is not getting end fully, not able to delete the folder backup, not able to cd backup also...

Because of this am not able to winscp the server...error as reading remote directory..

As usual, showing actual commands with their actual output can be
more helpful than vague descriptions or interpretations.

I don't see a "umount" command in your description. Why is that?

Again, actual commands with their actual output?

What happens if you reconnect the disk?

I removed it properly by SAM in OS level at Volume Group removal.

After removing also m able to see the /backup folder.

Now i just need to remove the /backup folder..

I removed the LV, PV by SAM in Os level.

But not able to remove the /backup folder and also not able to open it.

>umount /backup
umount: cannot unmount /dev/vdata/lv_back : Block device required
umount: return error 1.

Did you umount the file system first?

Unmounting a file system does not remove the mount-point directory.

As usual, showing actual commands with their actual output can be
more helpful than vague descriptions or interpretations. What, exactly
did you do, and what, exactly, did you see?

It may be too late for that now.

Have you tried rebooting the system?
