CLA-OIT System Maintenance Window



October 19, 2013

8:00 AM - 2:00 PM

Services Affected(avoid these during the window)

  • Research servers

  • Unix-based file servers (clio and thalia)

  • Database servers (including CSOM Oracle servers)

  • Web servers

  • CLA-hosted Active Directory File storage

    • This includes art-ema, cla-web, mctfr-fs5, cla-transana, and art-2d. User home directories and department shares (accessed throughfiles.umn.edu)are not affected.

  • CLA Terminal Server(wts.umn.edu): users may be unable to log in or may experience long waits attempting to log in during this window. Data synchronization may not function correctly until maintenance is finished. The service will not be shut down and may be used at your own risk during this window.

Services Not Affected(common services that users often ask about)

  • Google Apps (Gmail, Doc, Sites)

  • Active Directory File storage (Home, Shared, and Project folders onfiles.umn.edu)

Specific Details:

  • Hardware maintenance:

    • Maintenance is required on a storage device that hosts most CLA Research data, and some Active Directory file shares. This maintenance is being required by our vendor, and requires all of the attached servers to be down.

  • Security Patching:

    • perform routine maintenance tasks which will require rebooting most Unix servers.

  • Storage Migration:

    • Data is being migrated to new storage devices. This is unrelated to the storage device that requires maintenance.


What is a "system maintenance window"?

In order to correct a technical issue, install a security patch, or upgrade server hardware, CLA-OIT must occasionally disrupt normal networked services. Whenever possible, we plan such service outages in advance during times that minimize the disruption to our users.

Can I work during the maintenance window?

In general, CLA-OIT recommends that you avoid using the affected services during the maintenance window. Systems may be available during the maintenance window, but they can and will be shut down without warning and may be unavailable for hours at a time. So, use only at your own risk.

Can't this be done without disrupting service?

Certain tasks require server reboots and/or physically unplugging electricity. We do our best to group these tasks together to minimize the number of outages we schedule each year--which is generally less than five.

Can you reschedule this window to a more convenient time?

CLA-OIT strives to select times that minimize disruption. It isn't possible to pick a time that will not affect somebody. We also have to consider the availability of our staff and central OIT staff who run the data centers and networks. We try to soften the impact by announcing maintenance windows well in advance.

How do I find out more?
