Copying Files from CASTOR to Zuerich directly
How to
In order to copy files directly from CASTOR to a machine in Zurich, first do
export LHCBPRODROOT=/disk/dirac
. ${LHCBPRODROOT}/gLite/external/etc/profile.d/grid-env.sh
. ${LHCBPRODROOT}/lcg/etc/profile.d/grid_compat_env.sh
export X509_CERT_DIR=/disk/dirac/gLite/external/etc/grid-security/certificates
grid-proxy-init
which will prepare your machine for file-transport. Then do (e.g.):
lcg-cp -v 'srm://srm-lhcb.cern.ch:8443/srm/managerv2?SFN=/castor/cern.ch/user/myInitial/myUsername/myFile' file://home/hep/myUsername/myFile
The -v option just means verbose.
Note: You need a Grid Certificate to do this!
Transfer with a Script
In /home/hep/decianm/scripts you will find the script castortrans.sh. The best is to make an alias in your .zshrc-file like: alias castortrans=“source /home/hep/decianm/scripts/castortrans.sh”
The script can be used the following way:
- Open a new shell (it's always a good idea to open a new shell for transfers)
- Type
castortrans -i
This will set up your Grid environment.
- Type
castortrans -f yourFileOnCastor -t yourDestinationFile
. If you have the same username at CERN as locally in Zurich, yourFileOnCastor will be the path starting in your home-directory on CASTOR. yourDestinationFile will start in your home-directory in Zurich. If your usernames are not identical in Zurich and at CERN, you have to set them manually in the script.
- The script has been tested on a z-shell. As it is sourced and not only executed, it can not be guaranteed to work with all the other settings (hence the new shell).
