‘False’ Alarm Host connection failure
Posted by jlchannel - on May 28th, 2010 in Tips | 1 Comment »
For the past few weeks, my customers keep received an alarm “Host connection failure” email alerts via VMware vCenter but end up it’s a false alarm.
The email alert example as below:
Target: kulsrvprd01.malaysiavm.com
Stateless event alarm
Alarm Definition:
([Event alarm expression: Cannot connect host - incorrect Ccagent] OR [Event alarm expression: Cannot connect host - network error] OR [Event alarm expression: Cannot connect host - time-out] OR [Event alarm expression: Cannot connect host - time-out] OR [Event alarm expression: Host connection lost])
Event details:
Host kulsrvprd01.malaysiavm.com in DC1 is not responding
VMware Technical support team was told us this is a known bug in current release vSphere 4.0. The VMware engineering team is still working on it and the fix for this issue will be next released.
Quick Help: You can stop the alarm immediately after make any changes on the alarm definition such as changed the Alarm Action notification setting frequency from 5 minutes to 10 minutes.
Anyway, I would suggest to keep “Host connection failure” alarm enable. And let’s wait for the patches. Hope you’re aware about the problem.

Hi Jas,
i have a similar problem here. We use VDR and when we try to Backup a VM with VDR, which also has a Third Party Backup Client installed, the snapshot operation fails because of the quiescing, which obviously didn´t work with thirdparty vss providers installed (vssadmin list providers). when i restart the VM after snapshot operation has failed, the host on which the VM resides looses connection to vCenter Server but comes up again 1-2 min later. I think theres a problem with the vpxa or mgmt-vmware service because the host and other VMs on that host answer ping requests. Maybe i file a Support request of this behavior, but sadly i think VMware will blame the thirdparty vss provider.
