One way to find out your hard drive serial number information is if you open to open a terminal and run: sudo lsblk --raw -o name, type, serial. Further instructions for VMWare ESXi are included below.

Solution on a  VMWare ESXi Guest OS:

When VMWare ESXI creates a virtual machine hard drive, it does not always enable the setting to pass the hard drive serial number through to the guest OS. This prevents Nalpeiron from being able to identify the computer and the -3087 error code is returned.

How to check if the hard drive serial number is not available:

Linux

1. Open a terminal window

2. Run
   udevadm info --query=all --name=/dev/sda | grep ID_SERIAL

3. If nothing is returned, then the guest OS does not have a hard drive serial number

Windows

1. Open a command window

2. Run
   wmic diskdrive get SerialNumber

3. If the the SerialNumber is empty, the guest OS does not have a hard drive serial number

How to enable the hard drive serial number

...

:
