I’m in root on lxplus trying to open a data file and I’m getting a lot of errors back. This is my first time trying this, I’ve just set it up so I might have done that wrong. But I tried opening the file with:
root  TFile::Open(“root://cms-xrd-global.cern.ch///store/user/velicanu/Merged/Pythia8_Z30mumuJet_pthat30Norm_TuneCUETP8M1_5020GeV_cff_ppFOREST_PrivMC_v10/0.root”)
And it gives me:
160603 05:53:24 19223 Xrd: CheckErrorStatus: Server [xrootd.cmsaf.mit.edu:1094] declared: (error code: 3010)

Error in TXNetFile::CreateXClient: open attempt failed on root://cms-xrd-global.cern.ch//store/us … v10/0.root
So that’s a lot of errors. I think I’ve used the correct xrootd redirect per the CMS Offline workbook, I’m in New Zealand so I use the global one. I’ve loaded my grid certificate onto lxplus, set up my runtime environment in lxplus with cmsenv inside my CMSSW_5_3_32/src directory. I’ve set up ROOT with the 2 lines it tells me in the workbook:
I don’t know what’s happening so any help would be very much appreciated.
