From ROC CERN ROC Italy
To ROC DECH ROC Russia

  • Handover was from ROC CERN to Italy, but no Italian representative in the meeting. Last week, the number of alarms was low, and "everything went well".
  • Site concerned by escalation (GGUS:36262 and GGUS:37110), IL-IUCC, has been closed (confirmed by Kostas).

PPS Reports

  • No news other than what's on the Twiki (see agenda).

gLite Release News

  • See agenda

EGEE Items From ROC Reports

  • dCache at DESY (CMS SE) will be down 17 July, 09:00-15:00
  • dCache & LFC (ATLAS) at GridKa will be down 24th July, 07:30-12:00

Kostas mentioned getting "access forbidden" when accessing lcg-sam web-page. No one else is experiencing this; Steve suggested opening a GGUS ticket if the problem persists.

Documents for Review

Steve commented that the document sent out by Christoph Witzig on security command-line tools is an interesting one for site administrators. Please read it and send comments to Christoph. The other document for which comments are sollicited is from SA3 and TMB, and relates to multi-platform support. Not having not read it, Steve could not pass judgement.

Gunther Grein offered to decipher the Tier 1 alarm workflows introduced with the last release of GGUS (online 3rd July). A well-advertised workflow test is scheduled for Thursday, 17th, and will send alarm tickets to each Tier 1 site and test the recipient lists. Guenter will report on results next Monday.

Alessandro (ATLAS) asked which kind of answers were expected, and whether the recipients would be roused from their beds. Guenter explained that the tests would not be sent at night, but they would indeed be to the list of those normally to be woken out of hours.

WLCG Items

No experiment reports received.

WLCG issues coming from ROC reports

Nothing not already mentioned in the EGEE reports.

Upcoming WLCG Service Interventions

Steve mentioned that 2500 nodes are in the process of being switched off at CERN. All should be OK, but if an overlooked service disappears, please submit GGUS tickets to CERN ROC.

ALICE Service

CMS Service

LHCb Service

WLCG Service Coordination

Permanent link to CCRC daily reports will be added to agenda. Summary of previous week deemed to be useful.

OSG Items

Maria mentioned an unhandled OSG ticket GGUS:37446, open since 13th June. Rob replied that he had 3 tickets opened, but that it wasn’t one of them. Rob checked, and found that he had the ticket as closed (by Atlas ticketing system). He will forward resolution to GGUS. Maria would like to understand why the interface is broken. Rob explained that it's a manual step that needs to be fixed. However, no effort available so far and not deemed high priority. Rob will tell his staff to ensure GGUS gets updated with resolutions.

Rob wanted to double-check that OSG shouldn't be affected by CERN node removals, and Steve re-iterated that "shouldn't" was the keyword..
