    To minimize the impact to running jobs we are declaring a downtime for Tusker to complete this work. We will use this maintenance window to update various software components across the cluster.

  • 2017-01-04:  HCC Sandhills Extended Downtime
    Category:  Maintenance

    Facilities Management has extended the chilled water outage for Schorr Center until Jan. 9.
    Because of this we will maintain the service outage of Sandhills to avoid damage to the
    machines. The login node and filesystems will stay up. If you have any questions or concerns
    please contact hcc-support.unl.edu.


  • 2016-12-15:  Sandhills shutdown Dec. 21 - Jan. 4
    Category:  Maintenance

    Campus chilled water will be shut down completely from Dec. 21 to Jan. 4. Since the Schorr machine room relies heavily upon this supply for cooling, and since this overlaps with the holiday shutdown, we plan to shut down most of Sandhills over this time period. We will leave up the filesystems and login node, but all compute (worker) nodes will be turned off to avoid damage to any machines. If you have any questions or concerns please contact hcc-support@unl.edu.


    HCC has no control over this chilled water outage, and will take the above action since it will result in a significantly lower cooling capability.
