> If a SSVM in the zone is not available, meaning either it does not exist or the host
entry is not Up or Connecting, DownloadCommand will get routed to LocalHostEndpoint.  This
is particularily dangerous in a NFS setup.  If the mgmt server handles the DownloadCommand
it has sudo access to mount NFS and perform the action.  This mean the mgmt server is now
in the data path, or worse, it could hang if it does not have network access to the NFS server.
