Question LVM issue can not see a volume group that is clearly there

Hello out there!

I would like to add a logical volume to the rootvg as we know it has about 35 -40G available on it. When we went to check it we get an error stating that it doesn't exist...
We can however see the other 2 volume groups.

Can anyone help us gain access to it?

See details below:

# vgdisplay rootvg
Volume group "rootvg" not found

#df -h

You might check whether the "filter" rule in /etc/lvm/lvm.conf is improperly excluding a device from the scan.
