IT Support During Winter 2024 Energy Curtailment

December 10, 2024 by Lars Rohrbach

Due to the Winter Holiday, Energy Curtailment, and New Year’s Holidays, the Berkeley campus is officially closed for the period Tuesday, December 24 to Wednesday, January 1, reopening on Thursday, January 2, 2024. Additionally, much of campus is on reduced support for January 2-3.

All departmental computing servers will remain on and should be available during the break, but there will be no staff on site to provide any computing support or handle any requests. Automatic monitoring systems will alert staff to critical infrastructure problems, and any such problems will be dealt with on a best-effort basis. You may wish to turn off any workstations or printers in your office, to help with energy savings.

The IRIS Helpdesk office will be closed Monday, December 23 through Friday, January 3, re-opening on Monday, January 6. If you need assistance between January 2-3, please email help@eecs, and we may be able to schedule an appointment with you. Problem reports can be left on the Helpdesk voice mail (510-642-7777) or emailed to help@eecs during the campus closure period, but staff may not receive or reply to these messages until at least January 2.

Requests for network support or new IRIS accounts that are received after noon Tuesday, December 17 may not be processed until January 6, 2024.

During the break, Instructional labs will be locked, but the main servers will remain online (for details, see the Instructional website). Instructional support staff will occasionally monitor inst@eecs email over the break. Please be aware, though, that staff may not be able to respond or reply to messages until at least January 2.

Computing support staff will be monitoring their email when possible, so please use standard email addresses to report any urgent problems. As a reminder:

Instructional Computing Environment: inst@eecs

Research / Staff Computing Environment: help@eecs

DNS disruption for eecs.berkeley.edu, Nov 19

November 20, 2024 by Lars Rohrbach

Tuesday afternoon and evening, November 19, we had a disruption of DNS resolution for the eecs.berkeley.edu domain on the campus nameservers. This meant that many systems outside of the EECS network were temporarily unable to resolve *.eecs.berkeley.edu hostnames — so people may have been temporarily unable to reach EECS websites or deliver email to some @eecs.berkeley.edu addresses.

NetApp Fileserver Maintenance, Saturday November 30, 2024

November 13, 2024 by Lars Rohrbach

We are scheduling a NetApp ONTAP upgrade, to apply a necessary update to our NetApp fileserver, from 8am to 12pm on Saturday, November 30, 2024.

All Home directories and Project shares (CIFS/SMB and NFS) may experience disconnection during the update that may cause data loss on active, open files. Please close your open files and save them before Saturday morning. Services (e.g. webservice) that depend on this storage will also be temporarily down or unresponsive.

When maintenance is completed, NFS clients should automatically resume normal operation, but a reboot should help if they don’t. CIFS clients (such as Windows and MacOS) may need to remount filesystems, or simply be rebooted.
