Table 25. Event posting level
Event Description
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 Dell hosts, and creates
alarms for those events. Use these alarms to trigger actions from vCenter, like 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 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 need to 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 alarm
configurations have been changed since installation, those changes are reverted by using this button.
NOTE: To receive 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 hosts and chassis, or restore default alarms. You can configure events and alarms for each vCenter or for all registered
vCenters at once.
