Yeah, and there is a solution to it. You change the heartbeat timeout from 5 seconds to 10 seconds. This is discussed on Tim McMichael's blog. You can probably google/bing the proper article as easily as I can. :)
Personally, I don't like taking snapshots of entire VMs. For one thing, it's not a supported way to restore an Exchange server. From: Paul Hutchings [mailto:[email protected]] Sent: Thursday, March 22, 2012 12:49 PM To: MS-Exchange Admin Issues Subject: Issues snapshotting virtual Exchange servers in DAG? I've read that if you have a DAG and use a backup application that tries to quiesce the VM prior to snapshotting it, you can find that because the VM is "stunned" for a second or two, your DAG can failover, presumably because the heartbeat mechanism thinks the host being snapshotted has gone down/offline? Has anyone experienced this please? I'm still looking into adding a second Exchange 2010 box which would be virtual, and this is something that sounds like it could be quite a problem.
