vRealize Operations Manager provides an feature of High Availability so that you don’t have to worry when your one of the cluster node is down. HA creates a replica for the vRealize Operations Manager master node and protects the analytics cluster against the loss of a node. In this post we will see on How to configure High Availability in vRealize Operations Manager.
When any issue occurs with the master node, failover to the replica node is automatic and requires only two to three minutes of vRealize Operations Manager downtime. In case of High Availability replica node becomes the master node, and the cluster runs in degraded mode.
With HA, data stored on the master node is always 100% backed up on the replica node. To enable HA, you must have at least one data node deployed, in addition to the master node.
