We are experiencing a strange issue in our VMware environment, We have three esxi 5.5 hosts all managed by a virtual centre appliance which has been running well for some time now
Just recently our backups were failing for any VM that was sitting on host #, after much troubleshooting and diagnosis we found that, from this server (being a physical server, 2008 r2, running veeam, vsphere client) we could not login to host #2 directly using the vsphere client, we get "Call "ServiceInstance.RetrieveContent" for object "ServiceInstance" on Server host2" failed " error, yet any other machine on the network could log directly into this host with no issues at all
the other test was to see if we could download the VMX file of a running VM on that host, again from any other machine we can do this no issues, from this server, connecting to vcentre and browsing the datastore of a VM sitting on host#2 we get "file operation failed"
the strange this is that nothing has really changed, this appeared to literally just stop working. for this host.
