dhcp server downtime Wednesday November 4, 2015 07:00-07:30 am

November 4, 2015 by Mark Kraitchman

The departmental dhcp server will be down for a needed reboot to activate changes delivered by some RHEL patches.

Though the scheduled downtime is 7am to 7:30am, we expect actual downtime to be less.

scheduled dhcp server outage Wednesday September 30, 2015 7am to 7:30am

September 30, 2015 by Mark Kraitchman

The IRIS dhcp server will be down for maintenance on
Wednesday September 30, 2015 from 7am to 7:30am.
Devices with existing leases / IP assignments
on the IRIS wired and wireless networks
will not be affected. Devices broadcasting for
dhcp support will not be able to obtain an
IP assignment during the maintenance period.
We do not expect to need the full thirty
minutes for maintenance. New hardware is
being deployed to replace the old hardware
supplying DHCP service.

Miscellaneous services affected by project space outage

June 18, 2012 by Rob McNicholas

Last night’s outage of project.eecs caused a few other services to misbehave this morning. We believe all services are functioning as of around 11am.

An automatic process that generated configuration files for our DHCP server was generating truncated files, causing DHCP service to be out for some clients. That was resolved around 9:15am.

The server iris.eecs had some email stuck in its queue related to recent laptop purchase requests. Fixing that required a reboot of the server, and iris.eecs was down from around 10:30am until around 10:50am.

The ACG application server buffy.eecs apparently hung last night due to the project.eecs outage. It was rebooted this morning around 9am.

UPS Installation/Various System Outages

March 21, 2011 by IRIS Staff

Delivery is expected Monday for our new UPS which will be installed in the 290 Soda Hall server room. Some services will be down for short periods on Tuesday while they are moved off of room power and onto temporary power. Later in the week, there will be a second outage while those machines are moved onto the new UPS. Additionally, there may be a longer outage of our storage systems while some upgrades are done.

While I realize that this post is somewhat vague, a lot depends on exactly when the UPS is delivered and how long it takes to install it. I will be posting more refined notes to narrow down the scope of what services will be out (and when) as time goes on.

While we realize that there may be some inconveniences for some, please bear with us as we strive update our services and minimize outages for the future

Problems with various EECS services due to electrical work

February 24, 2011 by IRIS Staff

Due to work related to the installation of a new UPS, damage occurred to cabling used by the EECS Storage systems, causing unplanned downtime for a variety of EECS services, including:

* EECS Home Directories and Project space (should be back up)
* Unix Login Server – login.eecs (rebooted)
* DHCP (back up)
* Departmental Webserver (rebooting)
* Matlab licensing (still down)
* EECS IM/Jabber (still down)
* EECS Mailing lists – lists.eecs (still down)

Staff are working to bring these services and others back up now.

idsg.EECS.Berkeley.EDU provided services are down

November 11, 2010 by Mark Kraitchman

DHCP activations and updates for mobile devices and
desktops without a fixed IP address are not being processed.

DHCP support for mobile devices and
desktops without a fixed IP address is currently frozen
with the last update happening at Thursday November 11, 2010 12:30.

While trying to fix this issue, the IDSG web server and
the pages it server went off the network.

Staff is working on resolving these issues.

December 28th Shutdown

December 28, 2009 by IRIS Staff

IMAP/mail, home/project, Windows services (AD/WINS/printing), LDAP/NIS/DNS, DHCP and most other IDSG and IMG services will be affected. We will try to keep some basic network services running (DHCP, DNS/NIS), possibly in a reduced capacity.

While EECS-Secure, EECS-Guest and EECS-Open wireless LANS will be out of service during this time, the EECS and AirBears wireless LANS will remain operational during the outage.

The reason for this extended downtime is multi fold. The first is to repair the UPS that failed a couple of weeks back. The repaired unit will be placed back on line and extensive testing must be done to ensure it’s operation before we can depend on the UPS again. The second is to move data around which will allow us to remove from service a piece of software used to manage storage. This software is no longer under development and we need to remove our dependency on it. Lastly, some routine maintenance will be done which can only be done when systems are down. These are the kind of things that can only be done between semesters and we ask for you understanding during this disruption in service.

While the stated outage is from 10:00AM to 9:00PM, it may not take that long. This is a worst case scenario. If possible, services will be brought up sooner than 9:00 PM.

No Network Access for Some Machines

February 27, 2009 by Lars Rohrbach

As a result of some work being completed on the DHCP server this morning, some properly-registered mobile devices were refused DHCP support, so they were not granted access to EECS networks. Staff are in process of fixing the problem.

AirBears usage is not affected.
