Dept NetApp Filer Maintenance, 3pm January 3, 2022

December 21, 2021 by Lars Rohrbach

We will be performing an OS upgrade on our departmental NetApp filers (upgrading from OnTAP version 9.7 to 9.8), which will require a service outage from 3pm to 9pm on Monday, January 3, 2022. All NFS and CIFS access to the filer (home and project storage) will be down during that time. Services (e.g. webservice) that depend on this storage will also be down or unresponsive.

While we are scheduling a 6 hour maintenance window, we will attempt to minimize the service outage if possible.

When maintenance is completed, NFS clients should automatically resume normal operation. CIFS clients (such as Windows and MacOS) may need to remount filesystems, or simply be rebooted.

Following the lead of the campus, Google, and other industry leaders, IRIS will be ending support for the older security protocols TLS 1.0 and TLS 1.1 on the department web servers (e.g. people.eecs.berkeley.edu, www2.eecs.berkeley.edu, iris2.eecs.berkeley.edu, and any IRIS-hosted web site) on March 24, 2020. If you are using a modern web browser, you will not notice any changes.

Potential Campus Power Outage

October 8, 2019 by Lars Rohrbach

We have been alerted to possible PG&E power outages due to fire danger, and that campus power may be shutdown at some point over the next 2-3 days. If we receive notice of imminent shutdown, we will work to safely shutdown our NetApp fileserver and other critical infrastructure systems; this may occur on very short notice.

We will endeavor to update this News item as we receive any updates.

We recommend you proceed with shutting down any non-essential machines in advance, e.g. shutting down workstations at the end of the work day.

IT and Electrical Maintenance Shutdown, Sat. 6/16/18

June 15, 2018 by Derek Calderon

On Saturday, June 16th, the campus high voltage team will be cutting power to **Soda, Jacobs, Etcheverry, and North Gate Halls** to complete critical power grid maintenance. The electrical shutdown is currently scheduled for **8AM to 1PM** and these buildings will be **closed** during this time to all but critical staff related to the maintenance projects.

We are also taking this time to perform safety tests in our server and network rooms, as well as replacing the failed battery backup system in our primary server room. As a result, **the outage window for most IT services** (other than basic network connectivity) **is 11PM 6/15 – 9PM 6/16**.

Anybody with computers and electronics in Soda and Jacobs is **STRONGLY RECOMMENDED** to power off their noncritical systems when leaving the office on Friday, June 15. Critical systems **MUST** be powered off by 6AM on Saturday the 16th. This includes machines hosted in the 340 Soda server room, and a separate message will be sent to those system administrators next week.

As most of EECS’ IT infrastructure is hosted in Soda Hall, this will have some impacts which are detailed below. This will affect all EECS locations which are not undergoing electrical maintenance: **Cory, Sutardja Dai and Blum Halls, the Calvin Lab, and BWRC** as well as remote users.

* **Network infrastructure** (wired and wireless connections, including DHCP and DNS services) **will be offline for a brief period between 6:00 and 6:30 AM** in order to perform annual Emergency Power Off and Fire Alarm tests in our network core. Basic networking (including DHCP/DNS) will be restored by 6:30 and should remain up for the remainder of the day for all locations outside of Soda and Jacobs Hall.

* The IRIS website and portions of the department website including personal homepages, as well as other IRIS services that depend on file storage, will be shut down **starting at 11PM Fri. 6/15**

* Storage services, including home and project file storage, will be shut down at **12 AM Sat. 6/16**

* All services are scheduled to be **restored by 9PM**, but may be online earlier if maintenance is completed ahead of schedule.

As the IRIS website will be unavailable during this maintenance, https://status.eecs.berkeley.edu will be available for in-the-moment status updates.

Please contact help@eecs.berkeley.edu with any questions or concerns.
