RAL Tier1 Operations Report for 29th November 2017

Review of Issues during the week 23rd to 29th November 2017.
  • IPv6 issues have now been resolved – [Tier1] Unit 2 is master for IPv6 but there is no physical connections to that router from the switch core. Consequently the fail-over did not complete successfully. Once understood this was resolved 23/11/17.
Current operational status and issues
  • Certificate deployment issues with UKeScience 2B ICA 1.88-1 and SL6. Possible SHA-1/SHA-2 incompatibility with user application.
Resolved Disk Server Issues
  • GDSS896 (CMS_DEFAULT) has been returned to full production
  • GDSS771 has been returned to full production
Ongoing Disk Server Issues
  • GDSS753 - Faulty drive - Port 5:6. Being investigated
Limits on concurrent batch system jobs.
  • CMS Multicore 550
Notable Changes made since the last meeting.
