A co-worker was removing old NFS mounts and replacing them with new ones.   So same named NFS mount was being used.   He did an esxcfg-nas -d and then an esxcfg-nas -a and per our instructions, restart the mgmt agents so VirtualCenter would see them properly.   In doing this with U4 plus a month of patches, VirtualCenter lost connectivity with the host agent with a vim.fault.NotAuthenticated.

vim.fault.NotAuthenitcated

The fix is to disconnect and reconnect as you can’t put these systems into Maintenance Mode since VMotion doesn’t work.    Together we figured out a nicer way to do the mount point cleanup.

  • esxcfg-nas -d <mountpoint>
  • esxcfg-nas -a <mountpoint> …
  • vimsh -n -e “internalsvc/refresh_datastores”
  • vimsh -n -e “hostsvc/datastore/refresh <mountpoint>”
