OpenManage Integration for VMware vCenter Version 4.0 Web Client User's Guide

Hardware component health—Proactive HA

Proactive HA is a vCenter (vCenter 6.5 and later) feature that works with OMIVV. When you enable Proactive HA, the feature safeguards your workloads by proactively taking measures during redundant component failures in a host.

NOTE: All hosts from the Dell PowerEdge 12th generation and later, and the ESXi versions v6.0 and later that are part of a connection profile and successfully inventoried are eligible for Proactive HA.
To assess the status of redundant host server components, the OMIVV appliance updates the host component health status change to the vCenter server. The available status states of the major host server components, such as power supply, fans, and internal dual SD module (IDSDM) are:
  • Healthy (green check mark)—component operating normally.
  • Warning (yellow triangle with exclamation point)—component has a noncritical error.
  • Critical (red X)—component has a critical failure.
When OMIVV detects a component health status change (either through traps or polling), the health update notification of the component is forwarded with the status to the vCenter server. Based on the notification, the vCenter server takes either a manual or an automatic action, as configured by you. The vCenter server takes either of the following actions:
  • Place host in quarantine mode
  • Place host in maintenance mode
