Thanks for your reply. Here are the fqdn of one data server, one manager and one supervisor :

server : g26n03.hep.wisc.edu

manager : cmsxrootd.hep.wisc.edu

supervisor : s15n01.hep.wisc.edu

xrootd config file  is same for all these and roles are defined inside the config files. Both cmsd and xrootd depends on the same ‘/etc/xrootd/xrootd.cfg’ file.  Please find it in the attachment.
