Jaguar entered phase 4 of the upgrade on January 16. During this phase:

– Users will not have access to the 200-cabinet Cray XK6 system.
– Jobs in the queue at the time of the upgrade have been removed from the queue and must be resubmitted once the system returns to service
– The data transfer nodes (dtn01 and dtn02) can be used to access data on the /ccs home and /tmp work filesystems as well as the HPSS.
