vRealize Operations Manager 6 brings new high availability options to the table and has several deployment modes. In this 2-part series I will show you how to create a 2-node vROps High Availability Cluster mode cluster and put it behind a vShield Edge Load Balancer.
This is more of a “how to” post and less about the architecture, once again Sunny did a great job in his on-going vROps series explaining you about the bits and bites.
In my previous post I showed you how to migrate from vCOps 5.x to vROps 6. In order to create High Availability Cluster you must have the first node which is the Master node in place, the migration part is optional.
As you can see in the figure below, this is how a single node cluster looks like.
After deploying the second vROps virtual appliance VM, login to its URL and hit the “Expand an Existing Installation” button. Make sure you have all your DNS A records in place prior the deployment.
Enter the second node name, select “Data” as the node type and enter the Master node FQDN.
At this point, the second node will start its initial configurations and will be added to the cluster. Once it’s finished, click the “Finish Adding New Node (s)” button.
Notice the cluster is now expending. During this process both nodes will not be available so just wait, it usually takes around 10min to complete.
We now have two online nodes; Master and Data. Click the “Enable” button and follow the wizard in order to enable the “High Availability” cluster.
At this point the cluster will go offline and online again.
Notice that now the Data node becomes the Master Replica node and all your vROps objects and metrics are spread across the cluster.
As a final touch, go to vCenter and create a DRS anti-affinity rule for your vROps virtual appliance virtual machines.
You now have an up and running vROps High Availability cluster 🙂
In the next part I will show you how to put vROps cluster behind a vShield Edge Load Balancer, stay tuned.
