There was a software failure of the switch that serves many EECS services in Soda Hall this evening. That switch was rebooted restoring network connectivity to those servers but there was also a separate fiber channel failure involving home.eecs and project.eecs which both crashed. Work is ongoing to restore those services.

Sutardja Dai Hall switch updates
We’ve experienced unexpected blade reboots and multicast errors on some of the new switches in Sutardja Dai Hall. Per the vendor’s suggestion, I’ll be upgrading these to a newer software release.
Subnets Affected:
128.32.156.0/24, 128.32.247.0/25, 169.229.14.0/24, 169.229.222.0/23
The code revisions are close, so we expect to be able to perform a hitless upgrade; there should be no perceivable disruption. Nevertheless, I’m scheduling a 45 minute maintenance window (1715-1800) in case of problems.

network maintenance for BWRC network
We will upgrade the new image code for two BWRC switches on this Thursday May 14,2009. There will be brief network outages from 7:00AM to 7:10AM.
This will affect users who use wired connection in the BWRC lab and some machines that are connected to summit226-1 switch. Wireless in BWRC will not be affected. This upgrade should take less than 2 mins.
We regret any inconvenience this may cause. Please make your plans accordingly.

Planned Sutardja Dai Hall electrical shutdown
There will be a temporary shutdown of power on Sat May 2, from 8am to noon to verify Building Automation Function with loss of power.
All network equipment, including wireless, should run on UPS and then emergency power once the main generator kicks in. While we expect no problems, this is the first operational test of the network UPSs.
(Note: All switches successfully remained online over the weekend. May 4, 0900.)

AirBears Outage in CITRIS
It seem as a result of some work preformed by IST last night, AirBears clients in CITRIS are currently getting leases on the wrong subnet which renders them down. IST has been notified. The workaround would be to use one of the EECS WLANs.

Router Maintenance
As a followup to the network disruption Friday afternoon, I’ll be retesting the primary Cory Hall 10Gb module, and will reconnect the secondary links which were disabled Friday.
I anticipate no service disruption, but because the line card is suspect, and there is potential for problems, this work is scheduled for very early in the morning.
Unfortunately some of the problems we initially diagnosed as part of the routing troubles turned out to be server misconfiguration.
