Storage Problems
We are currently experiencing issues with IMAP, Home, and Project Storage. Staff are currently working on resolving the issue. News will be posted when services are restored.
There has been an outage on project and IMAP server earlier today. While the service has been restored, we are continuing to monitor it and investigate the root cause. Depending on the vendor recommendations, we may have to schedule additional work on a relatively short notice.
December 28th Shutdown
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.

Unplanned storage/email outage
Departmental storage went offline around 2:40PM affecting Home Directories, Project Storage and IMAP/E-mail service.
Service has been restored and IRIS staff are investigating further into the causes and full extent of this outage. If you are still having problems with these or other services, please contact the [IRIS Helpdesk – (formerly known as EECS Helpdesk)](mailto:help@eecs)

Widespread service disruption due to UPS failure
Last evening about 21:26 there was a power failure in the main EECS server room in Soda Hall. The UPS held up some systems until about 22:00 at which time staff shut the room down completely. Many EECS services were disrupted as a result. The problem was found to be in the UPS which fried the high voltage output terminal block. The terminal block was bypassed and the UPS has been removed from service until further notice. Most EECS computing services have been restored as of 03:15 this morning with the exception of the IRIS web server, which was restored around 10:15am Sunday.
Thanks to the staff who came in early Sunday morning to deal with this issue.

Follow-up SAN updates
Some of the issues with yesterday’s upgrade could not be resolved yesterday, so we’ll be addressing them today. We expect the services to stay up, but there could be minor delays/slowdowns or short outages.

Major Upgrades on June 6, 2009
On Saturday, June 6th, we will be doing major upgrades to some of our
backend systems. This work will start at 10 am. We expect that some of
services will start coming back up in about 3 hours, but due to the
complexity and extensiveness of the upgrades, the downtime may extend well
beyond the 3 hour mark. These upgrades are imperative for the continuing
reliability of the infrastructure services. We apologize for the
inconvenience.
The following services will be affected:
* Home directories
* Project space
* UNIX SWW
* Departmental/IDSG web servers
* IMAP (due to the additional work, IMAP will be down for an additional 2 hours)
* argus/login (UNIX login servers)
* Department websites www.eecs / www.cs and all hosted project sites
* Department mailing lists hosted on lists.eecs
* buffy and all ACG applications
* wikis hosted on wiki.eecs
* Department’s jabber server, jabber.eecs

Storage Area Network Maintenance
There will be some minor Storage Area Network (SAN) maintenance tonight at 5pm. Services are not expected to go down, but there could be occasional minor delays or very short outages.

Home Directory Downtime
home.eecs will go down briefly (a minute or two) twice on Saturday (03/07). The first downtime will be around noon, and the second will probably happen within the hour. This is to replace some failing hardware.
Clients that access home.eecs via Network File System (NFS) should not be affected by this scheduled maintenance. Clients that use Common Internet File System (CIFS), such as Windows and MacOS machines, may notice a disconnection (and should re-connect automatically).

Windows file service outage on home/project today
There will be a brief (few seconds) CIFS outage at 6pm today. This will affect Windows clients and Samba users.
Most people won’t notice the brief outage, but there’s a possibility that some Windows applications with open files may get a bit confused. We recommend all affected users save any open files before 6pm and wait until a few minutes after 6pm to resume work.
The purpose of this brief outage is to resolve a problem that has prevented some Mac users from accessing our file servers. Once we have confirmed that problem has been resolved, a separate announcement will be made.
