            Italy, France and CERN had not validated their ROC reports as of the 14:00 deadline. Reports show no major operational issues encountered during the reporting period, and no points to raise at this meeting.

            FZK-LCG2 wishes to convey the following information:

            • INFO: GridKa is going to move the remaining SL4 worker nodes (WNs) to SL5 starting next Monday (August 24) with the exception of the Babar share. After Friday 28th August SL4 WNs will no longer be available for WLCG VOs at GridKa.
            • OUTAGE: 24.08.09 7:00 am - 9:00 am UTC Due to cluster upgrade to SL5 next week two more CEs get configured to point to SL5. The ce-3-fzk and cream-1-fzk will be unavailable in the information system for the time. No jobs will be lost.
            • OUTAGE: 25.08.09 8:00 am - 8:30 am UTC Due to a necessary update of the SRM services, atlassrm-fzk.gridka.de and gridka-dCache.fzk.de will be down for up to 30 minutes. This downtime will only affect the *SRM* but no other dCache services!

            • SAM default DPM upgrade

              Last reminder that the default DPM used for SAM tests will be upgraded to SL4, and that sites with obsolete client S/W will start failing tests.

            • SAM MPI tests will be activated

              At the TMB on 05/08/2009 it was agreed that SAM MPI tests should be re-instated and results followed up.

            • SL5 Rules, OK?

              WLCG MB agreed on 4th of August to ask for the SL5 migration at all Sites, including the Tier-2 Sites.

              A web page is available to provide pointers to the relevant information to support the migration, including links to the necessary packages. (https://twiki.cern.ch/twiki/bin/view/LCG/SL4toSL5wnMigration).

              It is understood that the Experiments are all ready and able to use SL5 resources.
