About Upgrading HySecure Cluster
To upgrade HySecure cluster, you need to upgrade:
- HySecure Standby Cluster Manger Node
- Dedicated HySecure Gateway Node First
- HySecure Active Cluster Manager Node
Points to be considered before upgrading:
It is recommended to keep a downtime of 30 minutes per gateway node in the cluster. If there are 3 nodes, it is recommended to take 1.5 hours of downtime.
| Scenario | Details | Solution |
|---|---|---|
| Upgrade HySecure Standby Node | Cluster status in unaffected. If HySecure gateway is active on this node, this load will be disrupted. Load is shared by other gateway nodes in the cluster |
Users’s active connection to this HySecure Gateway node will be disconnected. Users do not have to re-authenticate. |
| Upgrading Dedicated HySecure Gateway Node | Load on HySecure Gateway node is disrupted. Load is shared by other Gateway nodes in the cluster. Cluster status is unaffected | Users’s active connection to this HySecure Gateway node will be disconnected. Users do not have to re-authenticate. |
| Upgrade HySecure Active Node | Cluster failover will happen. Temporary delay in routing connection from current active to standby. Standby node will become Active. If HySecure gateway is active on this node, this load will be disrupted. Load is shared by other gateway nodes in the cluster. |
Users’s active connection to this HySecure Gateway node will be disconnected. New user sessions while standby was being upgraded, will be become invalid and such users must re-login. Any configuration changes done on HySecure Active node will not be preserved and will be lost. |
