Viewing HA Information

If your system is deployed in HA mode, you can choose System Management > HA Management and view HA information, including the IP addresses and virtual IP addresses (VIP addresses) of the active and standby nodes, running time of the active and standby nodes, and metrics.

For a single server group deployed in HA mode and having data assets, pay attention to the following:

• If a VIP address is added, you need to manually change the proxy addresses of all existing data sources to the VIP address.
• If the VIP address is set to the original physical IP address of the single-node system during HA configuration, you do not need to change the proxy address of each data source.

To perform upgrade in the two-node HA scenario, choose System Management > High Availability, disable data synchronization, disable HA on standby server B (in dual-active mode, disable HA on either of the servers), and upgrade server B. After the upgrade is successful, enable HA on server B, disable HA on server A, and then upgrade server A. After the upgrade is complete, enable HA on server A and then enable data synchronization. This step minimizes the impact on services during the HA upgrade.
