EMERGENCY MAINTENANCE
Began 2:56 p.m. Aug 02, 2017

Due to a fire threatening our transformers, PG&E has advised campus we will be losing power.

IRIS is taking proactive steps to shut down as much equipment safely before we totally lose power.

See https://www.nixle.us/9HHZX for the warning from UCPD.

Soda Hall Power Outage June 21 2017

A power outage to Soda Hall which began around 12:30pm on June 21, 2017 has taken out many IRIS services.  This backup website will be updated until our main website is working again.

Update 3:15pm

Power has been restored to Soda Hall and staff are bringing up network equipment now.  The power conditioner in the main Soda machine room is having problems recovering.  Electricians are on site assisting.

This incident was fully resolved around 12:30am on June 22.  See this IRIS news article for details.

Brief outages to various IRIS services, tonight Apr 12, 6pm-6:30pm

Routine RedHat Linux operating system patches have been released which require system reboots. Starting at 6pm Wednesday, April 12, IDSG will be patching and rebooting affected servers. The following services will experience brief outages of 10 minutes or less between 6pm and 6:30pm.

  • Department mailing list services (lists.eecs.berkeley.edu)
  • Department jabber/xmpp service (jabber.eecs.berkeley.edu)
  • IRIS website (iris.eecs.berkeley.edu)

EECS Network Outage

The EECS networks became unreachable around 1:20pm on Monday, April 10.  Staff are investigating.

Update (2:15pm):   Staff investigation found the problem to be at or with one of the department border firewall devices. The secondary firewall device has been made primary now, and traffic is routing properly. Staff will further examine the problem firewall device, to narrow down the specific cause.

Fileserver maintenance, Nov 24 2016, 10am

Scheduled Maintenance

Services Affected: Home Directory Storage, IRIS Website, Project Storage, Repo Service, and Unix Login Server

Begins 10:00 a.m. Nov 24, 2016

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.
  • Upgrade NetApp OS.

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.

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

COMPLETION UPDATE:

FILESERVER MAINTENANCE COMPLETED
