MAKE sure, you have picked the right side and match the storage element to it..

For names of the possible storage elements and sites have a look at: http://atlas.web.cern.ch/Atlas/GROUPS/DATABASE/project/ddm/releases/TiersOfATLASCache.py
And infos on how to find fitting computing sites in general https://twiki.cern.ch/twiki/bin/view/Atlas/GangaTutorial427#4_5_Important_notes_and_useful_g

Also important: if you change something in the JO-file in the transfor-archive, make sure you change the softlink in
AtlasProduction/12.0.6.1/InstallArea/jobOptions/DC3_joboptions/
