How to Upgrade vRealize Log Insight Cluster – Step By Step

We have discussed about adding worker node to Log Insight Cluster in the previous article. We will discuss about How to upgrade vRealize Log Insight Cluster in this article. In this article, We will focus on upgrading vRealize Log Insight Cluster 4.0 to vRealize Log Insight Cluster 4.3. Upgrading vRealize Log Insight is not supported from vRealize Log Insight Integrated Load balancer IP address.

Upgrade must be done from the master node’s FQDN. During the upgrade, the master node is upgraded first, and restarts. Then each of the cluster nodes is upgraded sequentially.If the integrated load balancer is configured, its IPs are migrated among the cluster nodes so cluster services, including UI, API, and ingestion of incoming events, remain available throughout the rolling upgrade.

If any issue happened to any of the nodes during the upgrade process, The entire cluster will be automatically rolled back to the existing version prior to the upgrade. Cluster Configuration will be reverted to a known-good state captured before the vRealize Log Inisght cluster Upgrade. No loss to the ingested events. A system notification is sent when rollback finishes. After the issue is investigated and fixed, you can retry the upgrade.
