Upgrading or rebooting a cluster
Upgrading or rebooting a cluster has to be done by logging into each device or through the primary unit's Cluster Management page. You must upgrade the cluster in the following order:
- Workers
- Secondary
- Primary
It is highly recommended to setup cluster level failover IP set so the failover between primary and secondary can occur smoothly. If you do not want the failover to happen, you can change the secondary unit role to worker. You can either do this through the UI dashboard or the CLI prior to the failover, then change the role back after the unit boots up. |
