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.
To perform upgrade in the two-node HA scenario, choose System Management > HA Management, 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.
