We run a fully virtualised server setup, which includes the Solidworks License Server, running on Hyper-V. We use the built-in replication feature to replicate all our VM's to another host.
When testing replication failover the whole VM is powered up on the new host (the old VM is off). The license server host name, MAC address (set to static) and disk serial number all remain the same. However, when the replica server is brought up we still need to manually re-activate the Solidworks license. It seems to know that something has changed.
If all the machine information and virtual "hardware" remains the same I do not understand why this happens. Has anyone else had experience of this? Why it happens?
