Function Description:

This function provides high-availability services for virtual machines. When any one of the node's hardware, storage, or network fails, the HA mechanism will automatically restore the virtual machine (including virtual network devices) to run on other nodes to ensure business continuity.

Precautions:

When the management interface and edge port are disconnected simultaneously, only the virtual machine HA in the two-node scenario takes effect, and the HA in the three-node scenario does not.

Prerequisite

The virtual machine needs to enable the HA function, and other hosts have sufficient resources.

Steps:

Log in to the SCP platform, and navigate to Reliability > HA. You can set the Monitoring Sensitivity, and the setting is set for the entire cluster. Example: If the fault sensitivity level is high and the fault status is detected for 30 seconds, HA will shut down the virtual machine on the faulty node and try to restore the virtual machine to other nodes in the cluster.
