Event Description
Post only virtualization-related critical, and warning events Post virtualization-related events received from hosts into related
vCenters. The virtualization-related events are events that Dell
selects to be most critical to hosts that run virtual machines.
When you configure the events and alarms, you can enable them. When enabled, the critical hardware alarms can trigger the OMIVV
appliance to put the host system into a maintenance mode, and in certain cases, migrate the virtual machines to another host system. The
OpenManage Integration for VMware vCenter forwards events received from managed the Dell EMC hosts, and creates alarms for those
events. Use these alarms to trigger actions from vCenter, such as a reboot, maintenance mode, or migrate.
For example, when a dual power supply fails and an alarm is created, the resulting action puts the machine into maintenance mode, which
results in workloads being migrated to a different host in the cluster.
All hosts outside of clusters, or in clusters without VMware Distributed Resource Scheduling (DRS) enabled, can see virtual machines
being shut down due to a critical event. DRS continuously monitors usage across a resource pool and intelligently allocates available
resources among virtual machines according to business needs. To ensure that virtual machines are automatically migrated on critical
hardware events, use clusters with DRS configured Dell EMC alarms. The details of the on-screen message list the clusters on this
vCenter instance that might be impacted. Ensure that you confirm that the clusters are impacted before enabling events and alarms.
If you ever must restore the default alarm settings, you can do so with the Reset Default Alarm button. This button is a convenient
option to restore the default alarm configuration without uninstalling and reinstalling the product. If any Dell EMC alarm configurations
have been changed since installation, those changes are reverted by using this button.
NOTE: To receive the Dell events, ensure that you enable the events.
NOTE: The OpenManage Integration for VMware vCenter preselects the virtualization-related events that are essential
to hosts successfully running the virtual machines. By default, the Dell host alarms are disabled. If Dell alarms are
enabled, the clusters should use DRS to ensure that the virtual machines that send critical events are automatically
migrated.
About events and alarms for chassis
The events and alarms corresponding to a chassis are shown only at the vCenter level. The events and alarms settings for hosts at every
vCenter is also applicable at the chassis level. You can edit events and alarms settings from OpenManage Integration for VMware vCenter
within the Manage > Settings tab. From here, you can select the event posting level, enable alarms for Dell EMC hosts and chassis, or
restore default alarms. You can configure events and alarms for each vCenter or for all registered vCenters at once.
