RAL Tier1 Operations Report for 6th August 2018
Review of Issues during the week 30th July to the 6th August 2018.
|
- Although a relatively quiet week after the fun and games of the previous weeks power testing there were a couple of points of interest. The Production team experienced the intermittent working of its paging system (the cause was finally found to be a faulty SIM). This meant that there was no guarantee that call-outs were being sent to the relevant Duty Admin or On-Call. Despite this, periodic checking (at least every 2 hours), of mail and the RT queues did ensure that no call-outs were missed for longer than 2 hours i.e. within our accepted SLA.
- LHCb suffered a 2 servers outage over the weekend although they are now back in production. CMS continued to have their on-going SAM test issues (however, at time of writing these have been resolved). Finally, the Docker xrootd containers have been updated to use the Luminous client.
