The xprep command will issue the request to the redirector and exit without waiting for the restore to finish. The redirector will look up the requested files and record there location (which Xrootd server has a file) in its lookup cache. For files that are not on disk the redirector will send a restore request to a data server that is allowed to restore files (-s option). There is no notification ones all files are on disk but a client has to check for them self.
