Getting a certificate for the T2

If you need grid access on the T2, please follow all the steps below:

1. Get a Grid certificate (new).

   • If you already have a CERN grid certificate and are associated to a Belgian university, you can temporarily use the CERN certificate. But, for accounting reasons, we need you to get a Belgian certificate.
   • If you are not from a Belgian institute, request a certificate through your national institute.

2. Extract your certificate from your browser: Chrome | Firefox
3. Put your certificate on the UIs
4. Register to the VO

   • CMS
     1. Register to the CMS VO
     2. Check if your certificate is ok on SiteDB. Note the DN.
     3. Check that your certificate is the only one registered on the CERN website.
   • IceCube

   • Solid

5. Send a mail to the T2B support (grid_adminATlistserv.vub.ac.be) with your DN in order to have write access on the T2.

   • You can find it via the following commands on the cluster, once your certificate has been installed there:

voms-proxy-init

Send us the result of the last command
