Check Certificate UIs

We are going to check the following:

1. You can create a proxy using your certificate, which means it is registered to the VO
2. [CMS only] We can extract your username from siteDB based on your certificate.
3. You have write access to the T2_BE_IIHE

All the commands below need to be executed on an UI (mX machine). This requires your certificate is correctly installed there ( check here for all the steps, although it should already have been done).

1. Checking you can get a proxy with your certificate

voms-proxy-init --vo cms|icecube|beapps

should give you

Enter GRID pass phrase for this identity:
Contacting voms01.begrid.be:18004 [/DC=org/DC=terena/DC=tcs/C=BE/ST=Brussels/L=Brussels/O=Le reseau telematique belge de la recherche/CN=voms01.begrid.be] "beapps"...
Remote VOMS server contacted succesfully.


Created proxy in /tmp/x509up_u20522.

Your proxy is valid until Wed Nov 09 01:47:29 CET 2016

if not, then first check with the error message if you can't fix it (check -again- all the steps to install the p12 on the UIs have been followed), or send us a mail with the content of the error message.

[For CMS only steps] Get a working CMSSW environment

In order for the next steps to work, you need a working cmssw environment. You need to check out any CMSSW version available on the site. To determine which exist, do:

source $VO_CMS_SW_DIR/cmsset_default.sh
scram list CMSSW

This returns a list of CMSSW versions. Just pick one and do:

cmsrel CMSSW_<version>                (replace<version> by the version you chose)
cd CMSSW_<version>/src
cmsenv

3. [CMS only] Extraction of your username from siteDB

For this, we are going to use crab3. Source the init script to enable crab3:

source /cvmfs/cms.cern.ch/crab3/crab.sh

then do:

crab checkusername

It should print your DN, as well as your username.
If it doesn't work, make sure all the steps here have been followed.

4. Test write access to T2_BE_IIHE

• For CMS users, again, using crab3:

crab checkwrite --site=T2_BE_IIHE

It should give you the following

 Checkwrite Result:
  Success: Able to write in /store/user/rougny on site T2_BE_IIHE

If it doesn't work and all previous steps are fine, then send us an email with your DN, we will make sure it matches what we have.

• For everyone, you can try writing a file in your /pnfs directory:

gfal-copy file:///user/$USER/mytestfile srm://maite.iihe.ac.be:8443/pnfs/iihe/MYEXPERIMENT/store/user/$USER/

where MYEXPERIMENT is either cms, icecube or solid .

You should now be able to submit grid jobs ! Congratulations !! And that's the end of the story ...
