Over the weekend I had to run a failover test for an application within SRM. As SRM can only replicate down to the datastore level and not the VM level this meant doing a full test failover of all VMs but ensuring beforehand that all protected VMs in the Protection Group were set to Isolated Network on the recovery site. This ensure that even though all VMs would be started in the recovery site they would not be accessible on the network and therefore not cause any conflicts. The main concern, outside of a VM not connecting to the isolated network, was that the VM being tested and the application that sits on it are running on Windows 2000. Yes, that’s not a typo the server is running Windows 2000. The application is from back around that period as well so if it drops and can’t be recovered then it’s a massive headache.
Failover Test:
Step 1: Power down the production VM
Step 2: Perform Test Recovery
Go to Recovery Plans -> Protection Groups and select Test
When the prompt comes to begin the test verify the direction of the recovery, from the protected site to the recovery site. Enable the Replicate recent changes to recovery site. In most cases you will be already running synchronous writes between the sites and the data will just about be up to date anyway. It is recommended however to perform a recent change replication anyway to make sure that all data is up to date.
Click Next and then click Start to confirm the test recovery
