I can not remove a volume group

Hello,

I am a HPUX 11.11 administrator.

I have a volume group  I can not remove, neither using vgremove or vgexport, because is activated and has still missing logical volumen associated.  The logical volumens were deleted by force, removed from directly from /etc/fstab , so the file system associated.

 

In this way, if I try to execute a vgexport , I get the error :

vgexport: Volume group "/dev/caprep" is still active.

vgexport. Couldn´t export volume group "/dev/caprep"

 

And if I try to deactivate it, fails too:

vgchange : Couldn´t deactivate volume group "caprep"

 

Any idea, how can I force the deletion?

 

Thank you in advance

There is not any reference to the old file systems, neither the directory. In this way , I do not know whay it is still busy.

Device busy
