On Friday, July 5, from about noon to 2pm, we will be performing an OS upgrade for dhcp.eecs.
During this time, DHCP service will be handled by our backup DHCP server, so there should be no significant interruption of service — but no new DHCP updates will be processed (i.e. new system network registrations will not become effective until after the upgrade is complete).
[Read more…] about Upgrading dhcp.eecs Friday, July 5Microsoft will release their patches for the month on Tuesday, June 11th, 2024. Various IRIS Windows and Linux servers will be patched and rebooted Tuesday or Wednesday.
PRINT, WINTERM and WDS will automatically patch and reboot Wednesday, June 12th, at 3:00am. WINTERM may be unavailable until 10:00am Wednesday, depending on additional software updates.
Linux servers lists.eecs, iris2.eecs (for access to the network and roster databases), and login.eecs will be patched and rebooted Wednesday night. DNS servers cronus and rhea may also be briefly unavailable while rebooting at approximately 8:00pm Tuesday.
On Wednesday, June 12th, the departmental DHCP server is scheduled for downtime from 10pm to 10:30pm (actual downtime is expected to be shorter than scheduled).
[Read more…] about June IRIS Server PatchingAs noted following the January 4th Soda Hall power outage, an additional power outage for the second floor of Soda Hall is being scheduled to complete a circuit breaker replacement. Electrical power to the Soda Hall second floor will be down during much of the day on Thursday, June 13, 2024. Critical systems will be down from about 6am until perhaps 5pm.
Of primary note is that the department NetApp fileservers will be down, so any systems that depend on HOME or PROJECT storage will be shutdown or nonfunctional. Services that will be unavailable during the maintenance period include: department webservice (including people.eecs, www2.eecs and all other IRIS-hosted web sites), IRIS account & network forms, login servers (login.eecs, login-mfa.eecs, winterm.eecs), print server print.eecs, and outgoing SMTP server gateway.eecs.
Any systems that remain powered-on but make use of HOME or PROJECT storage may become unresponsive during this time. Rebooting after maintenance is completed is usually recommended.
Services that will remain online and available include: DHCP, EECS Active Directory, EECS LDAP, wired networking, DNS (cronus.eecs), and maillists (lists.eecs), and the main department website eecs.berkeley.edu.
[Read more…] about Soda Hall 2nd Floor Power Outage on June 13, 2024Just before 6:30pm, the campus experienced a wide-spread power outage. Most of the east side of campus remains without power at the time of this writing. There is currently no estimate for when power will be restored.
IRIS services in Soda and Cory will be either shut down imminently, or will soon become unavailable, as UPS power is used up. Once power is safely restored to campus, we will work to bring services back online to the best of our abilities.
[Read more…] about Unplanned East Campus Power OutageBeginning at about 3pm Friday, May 24, we will be upgrading the EECS Linux login servers login.eecs, login-mfa.eecs, and setsecretkey.eecs, from RedHat Enterprise Linux 7 to RHEL 8.
During the upgrade process, the servers will be unavailable for general logins, and will be rebooted multiple times. We anticipate that normal login service should be available by 9pm Friday evening.

[Read more…] about April IRIS Server PatchingWe are scheduling a NetApp ONTAP upgrade, to update our NetApp fileserver, from 8am to 12pm on Saturday, March 30, 2024.
All Home directories and Project shares (CIFS/SMB and NFS) may experience disconnection during the update that may cause data loss on active, open files. Please close your open files and save them before Saturday Morning. Services (e.g. webservice) that depend on this storage will also be temporarily down or unresponsive.
When maintenance is completed, NFS clients should automatically resume normal operation, but a reboot should help if they don’t. CIFS clients (such as Windows and MacOS) may need to remount filesystems, or simply be rebooted.
