Over the past month or so, I’ve been looking at disaster recovery of some of the vCloud Suite components.
In this configuration, I deployed vCO in HA mode, meaning that there were two vCenter Orchestrator servers, one running and one in standby mode. I am not going to repeat the detailed steps to set up vSphere Replication (VR) or Site Recovery Manager (SRM).
I also ensured that when the vCO servers were being setup, the SQL server database reference was via fully qualified domain name (FQDN) and not IP address. Both my vCO servers and SQL DB were eventually brought up on my recovery site, once the IP customization had run, and the prompt to change the IPAM DNS entries for my VMs had been dismissed. The network issue was due to the fact that the original IP from the protected site was still configured. This only happened on one occasion – on another failover attempt, the nodes came up in the correct state (one running, one standby).


Note that I also did this test with the vCO servers referencing the SQL server database using IP address instead of FQDN. My experiences of using vSphere Replication and Site Recovery Manager to protect and recover vCenter Operations Manager in the event of a disaster can be found here and here. Needless to say all the required steps such as pairing the sites, mapping resources, creating the protection group and recovery plan were all necessary. At this point, my vCO environment was up and running with new IP addresses on the recovery site, so now was time to validate that everything was working as expected.
I manually changed this in the Network portion of the Configuration UI here by selecting the new IP address (IP address of vCO server on recovery site).
However you should definitely only have one vCO server in a Running state, so verify this and rectify it before proceeding.
You will have to resolve the vCO configuration networking however post failover, and possibly flick the vCO configuration out of and back into cluster mode.


In that case, I had to change the vCO Configuration database settings on both servers and update the IP address to the new IP address on the recovery site.
Now it was time to look at vCenter Orchestrator (vCO) to see if that could be protected and recovered. One point to note however is that the SQL server database can use VSS (Volume Shadow Service) for application quiescing during failover.
I also added a prompt step to the SQL Server DB start-up which gave me an opportunity to modify the IPAM entries of my VMs and update them with DNS with new IP addresses on the recovery site.
