Invalidating the Hardware Finger Print - Replication and Disaster Recovery

Backup and Recovery Directory Server Laserfiche

Updated July 28, 2016

asked on February 20, 2015 • Show version history

Hello,

Do Laserfiche publish what changes are allowed before a license key becomes invalid? I think I heard somewhere that up two hardware changes are permissible. Is that true?

Note: License files for some applications include hardware fingerprints. If you make significant modifications to a computer on which one of these applications is installed, you may need to generate new licenses for applications registered on that computer.

I've a customer using VMWare SRM for disaster recovery. How much will they need to replicate? MAC Address? CPUID? Memory? Anything else?

Laserfiche licensing has some flexibility as far as hardware changes go before the license is invalidated. One or two changes will generally not invalidate it.

In your scenario however, this does not even need to be a consideration. You can simply keep a backup of their current working master/server license (depending on whether they have RIO or Avante) on another machine. This contains the HWFP information required to then manually deactivate. You can then simply deactivate the old license first (https://support.laserfiche.com/KB/1012301) using the old HWFP and hostid then reactivate the new VM when it is up. The deactivation process itself does not even need to occur on the same machine.

Do you know what the specific size of RAM or storage increase that will create a new hardware fingerprint?

One or two changes will not invalidate a license. It can be a combination of hardware changes.

Hi Raymond,

Yes, that's possible but it requires manual intervention. In the case of a fail over of a mission critical business system, the fewer steps (and the fewer human resources on hand) that are required the better.

That's why I was trying get a precisce answer about how much can change. How much RAM, is a good question. Also, where you say "one or two changes generally..." I need something precise for the disaster recovery planning. As the system architects will ensure as little changes as is needed.

If the honest asnwer is "Laserfiche do not provide details, as is their policy," for example, then that's fine too. At least that's something conctrete to give back to the customer.

Raymond,

In the article 1012301 above, does this article still apply in regards to laserfiche 10? specifically 10.1? The article does not include this version so I wanted to double check.

Our servers are also hosted in a Virtual Environment.

While troubleshooting performance issues we changed the RAM multiple times and never had a problem though. We changed from 2gb to 4gb to 10gb and back down to 8gb and never had to re-license it. When a second hard drive volume was added though the license went down (we didn't move the install directory or anything, just added one more drive to the VM). We were using Directory Server though so re-licensing was quick and easy for the Forms Server.

We changed nothing but memory allocation to the VM and it blew up Laserfiche licensing and thoroughly irritated our customer. Started working again when we set the vRAM back to its original value. To anyone with a formal DR plan I recommend including some verbiage regarding Laserfiche and what to do if/when it dies.

Does this apply to the Directory Server as well?
