Purpose of this page
- we are trying to collect information about upcoming Fermi computing outages (disks, oracle, network) to improve planning
- when planning an outage, please send an email to datalist and write the description here (including requested duration and preferred timeframe)
- we will try to combine outages as much as possible, in order to maximize uptime for time-critical services (FASTCopy, pipeline, etc.)
- once the plan is finalized, don't forget to send a message to glast-outage and the collaboration (if applicable)
Upcoming outage requests
- July 11 11:00 AM - noon. Replacing a bad fan on sulky34. Since that server holds the LAT raw data, FASTCopy ingestion will be stopped about an hour beforehand to let the pipeline drain.
July 9, 2012: 9:30 - 11:00 AM.
An internal disk on glast-oracle03, the host of the GLASTP database, is in danger of failing. This outage is to allow for its replacement.
