Using LVM in Linux Rescue Mode

So, the OS disk at  one of RHEL boxen on my vm farm is toasted and I need to check the health of the remaining disks, which are using LVM2. Booting to rescue mode with RHEL disk, I found out that I can’t right away use LVM related tool:

sh-3.2# vgscan
sh: vgscan: command not found

So what we need to do is to start the command with “lvm” prefix

sh-3.2# lvm vgscan
  Reading all physical volumes. This may take a while. . .
  Found volume group 'VG00' using metadata type lvm2 
sh-3.2#
