I have 1 server out of a cluster on ESXi5 that will not update via vUM. In the update logs I see:
2011-12-27T16:29:01Z esxupdate: downloader: DEBUG: Downloading http://[SERVER IP]:9084/vum/repository/hostupdate/csco/csco-VEM-5.0.0-metadata.zip to /tmp/tmpB8onUT...
2011-12-27T16:29:01Z esxupdate: Metadata.pyc: INFO: Unrecognized file vendor-index.xml in Metadata file
This is repeated for several patches. Any idea why one server would choke on the file, but others process it OK?
