ESXi 6.0 U1b - VM MAC Conflict alarm on Veeam Replicas

[mbrownwfp]

If you compare the MAC addresses on the source VM and the VM that the alarm references you will see that VMware has already changed the MAC on the second VM. The MAC Conflict alert is triggered but doesn't clear automatically when the MAC is changes on the replica/backup VM.

We've disabled the MAC Conflict alert on our Prod environment.

Editing the alarm works great, thanks!

Go to the VM MAC Conflict alarm definition. It’s in the vCenter inventory object under Manage > Alarm Definitions. Click the alarm and on the right, click Edit.

Under the bottom box that reads, “The following conditions must be satisfied for the trigger to fire”, add a condition that says the VM name does not end with “_replica”. Once applied, the alarm disappears for your replica VMs.
