General Information

Remember that this is a separate pool, so you should set in the environment STAGE_SVCCLASS=ATLASGROUPDISK in order to user the right pool. If you forget to set this, your files will end up in the default pool and soon become inaccessible. If you write in the right pool, but in any other directory different than /castor/, the files will be removed overnight, without prior warning.

export STAGE_SVCCLASS=atlasgroupdisk 

then you should be able to access the disk-space via usual rf-commands, i.e. rfcp, rfdir, ... The space is also available in the ATLAS Distributed Data Management System, under the endpoint CERN-PROD_PERF-EGAMMA. This means you can upload/download datasets there using DDM tools like dq2-put and dq2-get, or transfer datasets there using DDM subscriptions.
