NOTE: The OMIVV 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 EMC alarms are enabled, the clusters should use DRS to
ensure that the virtual machines that send critical events are automatically migrated.
Configure events and alarms
Prerequisites
● Enable SNMP events on the iDRAC settings page for all the OMIVV-managed hosts.
● To receive events from the servers, ensure that the SNMP trap destination is set in iDRAC. OMIVV supports SNMP v1 and
v2 alerts.
● Ensure that you set event posting level before enabling alarms for hosts and its chassis.
● To receive the Memory Page Retire (MPR) alarm for all hosts, ensure that the Enable Memory Page Retire alarm for all
hosts option is enabled for all hosts that are managed using OMIVV. In addition, set the Event Posting Level to Post all
Events or Post only Critical and Warning Events or Post only Vitalization-Related Events.
● To receive the alarms for all hosts and its chassis, set the Event Posting Level to Post all Events or Post only Critical
and Warning Events or Post only Vitalization-Related Events.
● Ensure that you set the same time zone between OMIVV and vCenter. If the time zone is different, you might observe delay
in posting alarms.
