Deciphering the hardware profile

Administration
Updated November 7, 2023

When the hardware profile of the server changes, is there a service online that will compare the 2 profile keys in order to determine what changed?

We have a system that has consistent unexpected hardware changes which is not the network MAC address and we are trying to find out what is being changed.

Can you switch to a domain license? This is the exact scenario they're designed to address.

As for what could be causing the HWFP to change, if the NIC/MAC is stable, and there are no obvious changes to CPU/RAM/etc. amounts, I'd look into if the VM is getting shuffled around to different physical hosts that might be running different hardware.

I'd personally start by trying to figure out how to use a domain license before diving into why the HWFP is changing.

Looks like to use Domain Licensing you must have Directory Server?

The hardware profile can see not only the virtual hardware presented to the operating system, but also the physical hardware that the hypervisor is running on?

I thought with VMWare we can no longer see anything physical and everything is presented virtually by the hypervisor.

Software cannot see the physical hypervisor or machine, but when VMs are moved it is possible some hardware identifiers could change if the 2 hosts have different hardware. Here are a couple of pages that explain it a little more. The first one is a page for VCenter Converter, but it is in regards to VM migration.

Thank you, I sent this over to IT to see if maybe they have something setup for performance reasons that automatically performs this operation

Unless specifically told not to, most VM solutions will move a VM to a new host when the VM is restarted. The main reason for a VM restart that I've seen in the past is when Windows Updates are applied.

In regards  to VMWare, VMs can be VMotioned for a number of reasons. They could be done manually if a host needs to have maintenance done and all VMs are moved off to another host. They could also have it set up so if a host starts to have too much CPU usage (or whatever parameters they determine), VMs could be automatically VMotioned to another host to balance things out.

VMs need to have the ability to be moved to different hosts. What you can ask for is for the settings to be set such that if there are 2 or 3 hosts that have the same hardware, your VM is only allowed to be VMotioned to those hosts and not another host that has vastly different hardware, if possible. They can set up which hosts the VM is allowed to run on.

We just don't want the hardware presented to the operating system to change, because Laserfiche was installed on a specific set of hardware and will not operate on another set of hardware without being installed again.

That is correct.
