RAL Tier1 Operations Report for 18th March 2019
Review of Issues during the week 4th March 2019 to the 18th March 2019.
|
- All very much business as usual in Tier-1 world.
- We have experienced an issue with ATLAS SRM tests where ATLAS are requesting incorrect CASTOR space token. Although this is not overly an issue for ATLAS, it does impact the apparent availability metrics for the Tier-1. This have been passed to the appropriate liaison to resolve.
