can’t mount /dev/vg00/var

I’m trying to access data on a hard drive using a rescue system. I’ve mounted the root partition as so:

mount /dev/md1 /mnt

If I do

cat /mnt/etc/fstab

I see

/dev/vg00/var  /var     xfs

So I tried:

mount /dev/vg00/usr /mnt/usr/

But I get the error message:

mount: special device /dev/vg00/usr does not exist

Why does it say that the device doesn’t exist if it exists?

Try this:

pvscan
vgscan
vgchange -a y

And after that try mounting again.
