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.

Fileserver maintenance 10apr18

April 10, 2018 by Pathma Venasithamby

This should be mainly non disruptive, but be forewarned in case of mount issues.

Any CIFs shares will experience a disconnect but upon reconnect it should reconnect to the the other HA node. If someone is doing a copy over a share they will have to restart that.

Fileserver maintenance 30th Jan

January 30, 2018 by Pathma Venasithamby

Due to the power failures on 20th Dec, the department fileservice has suffered some damage, and there is a non functional management interface. This needs to be repaired or replaced. This should *not* be disruptive to users, as per Netapp. But it does involves reseating or replacing a motherboard on one of the nodes, so please be forewarned that one of the clusters will not be running in HA mode during the replacement.

Fileserver maintenance

Upgrading NetaApp OS 11am-2pm on Presidents Day holiday 20th February

Department fileservice may experience some short interruptions during the maintenance window, approximately 11am until 2pm.

Many services that rely on access to department fileservice (home directories, webservice, repo service, NFS and CIFS mounts, etc) may notice some performance issues during this period.

We expect most, if not all, clients to recover automatically once work is complete. This news item will be updated to indicate when the maintenance is completed.

Systems still experiencing mount issues after the maintenance window, would need to remount or reboot.

EECS Full Network and Service Outage, Thurs. 12/22/16 7:30AM

December 22, 2016 by Derek Calderon

We will have a full system shutdown on Thursday, December 22nd at 7:30 AM to perform necessary fire and emergency power testing in our server rooms. The entire EECS network and all hosted resources will be offline during this maintenance.

This will affect networking in the following locations:

Wired and wireless networks offline:
* Soda Hall
* Cory Hall
* Sutardja Dai Hall
* Jacobs Hall
* BWRC

Wireless networks offline, wired remains online:
* Blum Hall
* Calvin Lab

Hosted resources such as the EECS website, file servers, etc. will be offline and globally inaccessible.

The facilities maintenance window is scheduled from 7:30 AM to 1 PM, but we anticipate the network and critical services should be back by 11AM if all goes well.

The intent is to perform these tests annually going forward; however we will learn from this year’s procedure and aim to keep more critical services online in the future.

If you have any questions about this maintenance, please contact help@eecs.berkeley.edu.

November 24, 2016 by Pathma Venasithamby

On the morning of Thursday, November 24 (Thanksgiving Day), we will be performing some disruptive maintenance on the department fileserver:
* Recable to new network datacenter switches.
* Upgrade cluster switches firmware.

Department fileservice will be unavailable during the maintenance window, approximately 10am until 1pm. Many services that rely on access to department fileservice (home directories, webservice, repo service, etc), will either be offline or will fail to work during this window. All NFS and CIFS mounts will be affected.

We expect most, if not all, clients to recover automatically once the fileservers are back online. This news item will be updated to indicate when the maintenance is completed.
