CHPC Major Downtime: Tuesday, June 23rd, 2009 - ALL DAY

Posted: June 9, 2009

Duration: From 7:00 a.m. until evening

Systems Affected/Downtime Timelines:

  • All HPC Clusters - will be taken down starting at 7 a.m. until sometime in the evening.
  • Intermittent outages of CHPC supported networks (INSCC, 7th & 8th floor of WBB and CHPC supported networks in Sutton) from 8:30 until Noon.
  • All CHPC supported desktops mounting CHPCFS file systems. From about 7 a.m. until late afternoon.
  • INSCC Machine room - no cooling from 8:30 until the repair on the faulty electrical.

    Instructions to User:

    • Expect intermittent networking outages in INSCC, WBB 7th and 8th floors, and CHPC supported networking in the Sutton building.
    • Desktops mounting the CHPCFS file systems plan for CHPCFS to be unavailable most of the day. Those with Windows and Mac desktops should be able to function, but will not have access to the CHPCFS file systems. CHPC recommends that you reboot your desktops after the downtime.
    • All HPC Clusters will be down most of the day. One maintenance task will be updating the queuing system on the clusters. We expect queued jobs to ride this out, but there is a possibility we may lose queued jobs.

    During this downtime maintenance will be performed on the electrical system in the INSCC datacenter, requiring most equipment to be shut down. Physical Maintenance will be performed in Komas. CHPC will be performing maintenance on the clusters and networking in the Komas machine room network.

    All file systems served from CHPCFS will be unavailable for a good part of the day. This includes HPC home directory space as well as departmental file systems supported by CHPC. We will work to get things online as soon as possible, hopefully by late afternoon.
