hi,

I don't like the question marks....

Where does this disk come from? Was it in use before? Just added to the system?....

pvdisplay does not give an error, so it should be in the lvmtab...

Was a pvcreate already performed on this disk after adding it to the system?

good luck,
Thierry.

John,

this look exactly as if someone had created an lvol and "removed" it not using lvremove but did rm /dev/vguv/lv_whatevername /dev/vguv/rlv_whatevername

To get this straigt you can use
cd /dev/vguv
ll

look at the group file and the 2 numbers after 0x
*suppose* it was 0x030000
look at lvux_d01 and lvux_ins
they should have minor numbers 0x030001
and 0x030002 then

So enter
mknod lvol_nix b 64 0x030003
mknod rlvol_nix c 64 0x030003

Then pvdisplay will show lvol_nix instead of the ????s

The use lvremove -f /dev/vguv/lvol_nix

That should settle it

MAYBE there is a file with 0x030003 named
rand-something

Then enter
mknod and-something b 64 0x030003

Else enter
mknod lvol_nix b 64 0x030003
mknod rlvol_nix c 64 0x030003

Then pvdisplay will show lvol_nix or lvoland-something instead of the ????s

The use lvremove -f /dev/vguv/lvol_nix

That should settle it
