False Alerts

I keep getting alerts that 8 of my vmware host servers are down when they are not.  It is the same 8 servers every day.  The details of the alert are as follows:

Name:  omeAlertSystemDown

Type:  SNMP

Catalog:  MIB-Dell-OME

Severity:  Critical

Format String:  $1: $2

SNMP Enterprise OID: .1.3.6.1.4.1.674.11000.1000.100.1

SNMP Generic Trap OID:  6

SNMP Specific Trap OID:  1001

I do not have snmp enabled on the discovery of these devices, I use only WS-MAN.

Rather than create a rule to ignore this alert on these devices only, how can I stop these alerts on these devices?

Thank you!
