Viewing events
Ensure that you configure events before you can view them in the Events tab. See Configuring events and alarms.
View the events for a host, cluster, or data center in the events tab.
1. In the OpenManage Integration for VMware vCenter Navigator, click Hosts, Datacenter or Clusters.
2. In the Objects tab, select a specific host, data center, or cluster for which you want to view events.
3. In the Monitor tab, click Events.
4. To view the event details, select a specific event.
Hardware component redundancy health—
Proactive HA
NOTE: Only servers that support redundancy health status for the supported components (power supply, fans, and
IDSDM) are eligible for Proactive HA.
NOTE: The configured Proactive HA policies on the Proactive HA cluster might be affected when global alerts are
configured through OMIVV.
NOTE: Proactive HA is available only on the platforms that support redundancy on power, fan, and IDSDM.
NOTE: Proactive HA feature is not supported for PSUs for which redundancy cannot be configured (for example, cabled
PSUs).
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 based on degradation of redundancy health of supported components in a host.
NOTE:
All hosts from the 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.
After assessing the redundancy health status of the supported host components, the OMIVV appliance updates the health status change
to the vCenter server. The available states of redundancy health status for the supported components (power supply, fans, and IDSDM)
are:
• Healthy (Information)—component operating normally.
• Warning (Moderately degraded)—component has a noncritical error.
• Critical (Severely degraded)—component has a critical failure.
NOTE:
The moderately degraded and severely degraded states are represented as Warning in the Type column on the
Events page.
NOTE: An Unknown health status denotes the unavailability of any Proactive HA health update from the Dell Inc
provider. An unknown health status might occur when:
• All hosts that are added to a Proactive HA cluster may remain in the unknown state for a few minutes until OMIVV
initializes them with their appropriate states.
• A vCenter server restart may put the hosts in a Proactive HA cluster into an unknown state until OMIVV initializes
them with their appropriate states again.
When OMIVV detects a change in the redundancy health status of supported components (either through Traps or polling), the health
update notification for the component is sent to the vCenter server. Polling runs every hour, and it is available as a fail-safe mechanism to
cover the possibility of a Trap loss.
Configuring Proactive HA for Rack and Tower servers
To configure for the Rack and Tower servers, perform the following steps:
Ensure that all hosts are properly configured for redundancy of all the three supported redundant components (power supply, fans, and
IDSDM).
