[edit] Storing ATLAS Files on the GRID

You need an LCG UI machine for this.

First, check whether you have created your LFC catalog directory:

lfc-ls /grid/atlas/users/<your username>/

If it exists, good. If not, create it with:

lfc-mkdir /grid/atlas/users/<your username>

Now, look up your local storage element:

lcg-infosites --vo atlas closeSE

This will return a long list; the relevant part for TRIUMF looks like:

Name of the CE: lcgce01.triumf.ca:2119/jobmanager-lcgpbs-atlas
Name of the close SE:   lcgse01.triumf.ca
Name of the close SE:   sc4.triumf.ca

Name of the CE: snowpatch.hpc.sfu.ca:2119/jobmanager-lcgpbs-atlas
Name of the close SE:   wormhole.westgrid.ca

Since the TRIUMF ones are pretty experimental, go with wormhole (the WestGrid dCache I/O node for ATLAS):

lcg-cr -v --vo atlas -d wormhole.westgrid.ca -l lfn://grid/atlas/users/<username>/myfilename.root file:/my/full/local/path/myfilename.root

This worked for me and returns a gsiftp destination URL and guid (probably useful to note these down as they are not very memorable, but you can use them to copy the file directly using globus-url-copy gsiftp...). But the nice thing is that I can also access the file via

lfc-ls /grid/atlas/users/<username>/myfilename.root

and copy it back (or to somewhere else) using:

lcg-cp -v --vo atlas lfn://grid/atlas/users/<username>/myfilename.root file:///any/full/local/path/somefilename.root
