CHAPTER 4 – DEFENSEPRO VA
RECOVERY AND LICENSE MIGRATION
PROCEDURE
Creating a new VM machine to replace a failed machine (recovery procedure) requires the re-
installation of the VA licenses. Because DefensePro VA licenses are dependent on the virtual MAC
address or IP address assigned to the original VA, to use the same licenses, the new VA must have
the same MAC address or IP address as the original VA. Otherwise, the new VA will need new
licenses.
To migrate the VA licenses to the new machine, it is crucial that a list of license strings and MAC
address should be maintained for each VA, because in case of disaster the VA licenses and MAC
addresses may not be otherwise available.
This chapter describes the procedure for migrating existing VA licenses to a newly installed machine
and DefensePro VA recovery procedure in case of disaster recovery.
Note:
Do not start the appliance before the procedure is completed. If the appliance is started
before the Linux UDEV sub-system recognizes the new MAC addresses and creates a new rule file, if
you later change the MAC addresses and start the system again, the UDEV will add the new MAC
addresses to the rule file. The new NICs will receive non-acceptable names (eth4, eth5, and eth6).
Recovery and License Migration Procedure over a KVM
Hypervisor
This section details the recovery and licensing procedures for DefensePro VA running on a KVM
hypervisor.
Recovery Procedure
The following recovery procedure creates a new VM machine to replace a failed machine.
This recovery procedure also includes the re-installation of the VA licenses.
Note:
For this procedure, you have to find and record the original MAC addresses in order to
perform the recovery procedure. To find the MAC address, you can use a Virtual Machine Manager
(virt-manager) which is a graphical tool for creating and managing guest virtual machines.
To perform VA system recovery
1. Install a new machine for the DefensePro VA.
2. Find and record the original MAC address.
To find the MAC address, use a virt manager application to find the second virtio interface (as
shown in the example below).
