Changes

Below are a few of the changes which can cause this issue:

1) Some changes have been made with the LVM configuration like adding a new LUN from SAN which was previously being used as LVM on another decommissioned system and have been added to new system without proper cleaning from SAN side and has previous metadata.

2) A new VG was created using the same name which already exists on the system.
