The VM (Factory Talk Historian/PI Database Server) is hosted on an HP BL460C Gen9/Gen10 Blade running VMWare ESXi 6.5. The VM files and disks are on a shared Datastore (VMFS 6) residing on an DELL/EMC Unity 450F. Then VM gets backed up daily using VEEAM. As I understand, VEEAM makes a backup of the VM by taking a temporary snapshot and deletes that snapshot when backup finishes.
The volume serial number B0C53B0B belongs to the C: drive (System Drive) of the VM (Factory Talk Historian/PI Database Server). Every time we are forced to reboot the server because of Windows Security Patches, the licensing breaks. Somehow, Licensing is seeing a new DISK_SERIAL_NUM. Please see below:
