Virtualization

Replaced certificates and get vSphere HA Agent unreachable? I have heard this multiple times in the last couple of weeks. I started looking in to it and it seems that in many of these scenarios the common issue was the thumbprints. The log files typically give a lot of hints that look like this: [29904B90 verbose 'Cluster' opID=SWI-d0de06e1] [ClusterManagerImpl::IsBadIP] is bad ip Also note that the UI will state “vSphere HA agent unreachable” in many of these cases. Yes I know, these error messages can be improved for sure. You can simply solve this by disconnecting and reconnecting the hosts. Yes it really is as simple as that, and you can do this without any downtime. No need to move the VMs off even, just right click the host and disconnect it. Then when the disconnect task is finished reconnect it. "Replaced certificates and get vSphere HA Agent unreachable?" originally appeared on Yellow-Bricks.com. Follow me on twitter - @DuncanYB.
