Hydra DDN Maintenance Completed

Hydra today Tue, May 17th, received a new disk enclosure for the DDN storage array. That was necessary to recover completely after several components of channel E enclosure had failed.

DDN and GPFS appear to be stable and the system has returned to service. Users may now re-establish interactive sessions and submit batch jobs.

That was a major h/w maintenance so please let us know if you notice anything out of the ordinary.
