Check Certificate UIs
We are going to check the following:
- You can create a proxy using your certificate, which means it is registered to the VO
- [CMS only] We can extract your username from siteDB based on your certificate.
- 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
should give you
Enter GRID pass phrase for this identity: Created proxy in /tmp/x509up_u20522. Your proxy is valid until Fri Nov 06 04:33:33 CET 2015
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 .
