        • <big> Service type change and SAM LFC Tests.
          https://savannah.cern.ch/task/?7108

          On Wednesday when Gilles implements the new, sanitized, GOCDB service names, SAM will submit LFC_LOCAL and LFC_CENTRAL tests instead of the current LFC tests. The only difference is that an LFC-ping test has been added, and the tests will no longer attempt to write to read-only LFCs. An EGEE briadcast will be sent after the meeting.

        • <big> LHCb report </big>
          1. Some modification on the critical SAM tests for LHCb
            Set new critical tests targeted to test the infrastructure under the LHCb perspective: JS Shared Area and CSH test from ops. This gives a disentangled from DIRAC view of the health status f the site and guarantees to have always SAM test results for the CE (that ultimately for LHCB suffered several internal problem preventing to have CE properly rated)
            Further to that we also have set critical (after month of test) the condition DB test (only valid for T1)
            For the SE two more LHCb specific tests are also coming soon (they are in a test phase before becoming critical)

          2. A second point is about warning sites that LHCB is going to broadcast the request for the pilot role as discussed at the GDB and last Workshop.

          3. Non critical GGUS ticket submitted last week against GridKA today escalated at the daily ops meeting it looks like from the answer that streams to GridKA are off since half a year now. Some words from GridKA are welcome
