You can automatically upgrade a cluster to vRealize Log Insight 3.6.

About this task

Upgrading vRealize Log Insight must be done from the master node's FQDN. Upgrading using the Integrated Load Balancer IP address is not supported.

During the upgrade, the master node is upgraded first, and restarts. Then each of the cluster nodes is upgraded sequentially. You can see the current status of the rolling upgrade seen on the Admin > Cluster page. 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. Low-level details are written to the upgrade.log file on each individual node. A system notification is sent when upgrade completes successfully.

If an issue is encountered affecting one or more of the nodes during the upgrade process, the entire cluster is automatically rolled back to the original, working version. Because configuration changes performed after the upgrade started might be inconsistent or invalid, the configuration is reverted to a known-good state captured before upgrade. No ingested events are lost. Progress is written to rollback.log file on each individual node. A system notification is sent when rollback finishes. After the issue is investigated and fixed, you can retry the upgrade.

Prerequisites

  • Verify that you are applying the upgrade for a supported upgrade path. See vRealize Log Insight Upgrade Path.

  • Create a snapshot or backup copy of the vRealize Log Insight virtual appliance.

  • Obtain a copy of the vRealize Log Insight upgrade bundle .pak file for the release you are upgrading to.

  • Verify that you are logged in to the vRealize Log Insightportnumber Web user interface as a user with the Edit Admin permission. The URL format is https://log-insight-host, where log-insight-host is the IP address or host name of the vRealize Log Insight virtual appliance.

Procedure

  1. Click the configuration drop-down menu icon and select Administration.
  2. Under Management, click Cluster.
  3. Click Upgrade from PAK to upload the .pak file.
  4. Accept the new EULA to complete the upgrade procedure.

What to do next

After the master node upgrade process is complete, you can view the remaining upgrade process which is automatic.

Check for the email sent to the Admin to confirm the upgrade completed successfully.
