Hi, I've a real newbie question. I've been investigating migrating the T2K grid software for files transfers/job submission from LCG/WMS to DIRAC. As part of this I was hoping to register a sub-section of our data files into the GridPP DIRAC instance to begin experimenting. I've read that this is possible via the CLI using the 'register file' command. The data is current stored at 3 locations, KEK, TRIUMF and RAL such that for a typical file the output of lcg-lr is: srm://kek2-se01.cc.kek.jp/t2k.org/nd280/raw/ND280/ND280/00013000_00013999/nd280_00013512_0005.daq.mid.gz srm://srm-t2k.gridpp.rl.ac.uk/castor/ads.rl.ac.uk/prod/t2k.org/nd280/raw/ND280/ND280/00013000_00013999/nd280_00013512_0005.daq.mid.gz srm://t2ksrm.nd280.org/nd280data/raw/ND280/ND280/00013000_00013999/nd280_00013512_0005.daq.mid.gz The output of dirac-dms-show-se-status does not appear to have kek2-se01.cc.kek.jp, srm-t2k.gridpp.rl.ac.uk or t2ksrm.nd280.org (or is this CA-TRIUMF-T2K1-disk?) as available SE. Is it possible to add new SEs to the GridPP deployment of DIRAC? Cheers Trevor Stewart
