Hydra Cluster : New Login Node and Maintenance Completed
Dear Hydra users,
we are opening up a new node officially known as "tera.tamu.edu" to host the interactive login sessions for Hydra. Interactive logins can take place against this IP name. Interactive and batch processing has restarted.
NOTE: We have modified the DNS (IP Name Services) information so that effective 02/07/2013 at around 9:00AM, IP names hydra1.tamu.edu and hydra2.tamu.edu will map to this host.
We applied a number of reconfigurations on the cluster to allow tera.tamu.edu (or f1n2) take over the roles the crashed node (f1n9 or hydra1.tamu.edu) was playing, including, GPFS I/O server, alternate LL scheduler and interactive host. We restarted LL to clear stale state information for jobs. Please let us know if you find something that is not working as expected.
