Submitting to all sites

There is a pre-prepared DIRAC script for submitting SAM jobs to all sites.

$ dirac-lhcb-sam-submit-all

If problematic sites are found, then they can be excluded from the daily SAM test by adding the DIRAC site name to the following CS option:

/Operations/SAM/BannedSites

Tests are normally run by hand for CERN.

Targetting one site

If a job fails at a site, you may want to target it specifically to find out more about what is going on.

$ dirac-lhcb-sam-submit-ce

To get the CE of the site, use this tool to query the CS:

$ dirac-admin-site-info LCG.UKI-SCOTGRID-ECDF.uk

In case of shared area corruption, the targeted job should specify:

• CE of the site
• The existing lock file should be removed (--removeLock=True)
• Deletion of the shared area (--deleteSharedArea=True)

This will help to correct the problem. Only one such job should be sent at a time to prevent both jobs being able to write to the shared area simultaneously.
