Some classroom podium workstations were unable to load Operating System (OS) images. Client’s were seeing an error message “Vdisk is lost. Press any key to continue”
Some classrooms managed by IST were potentially affected. The specific locations known to have been impacted were:
The affected client’s were unable to boot the classroom podium workstations.
Start: 2017/06/05 10:02 - Client's began reporting CCIS podium workstations were not booting.
2017/06/05 10:30 - IST analysts were notified of the issue and were dispatched to the affected sites.
2017/06/05 10:40 - Error message confirmed as “Vdisk is lost. Press any key to continue.”
2017/06/05 10:45 - IST analysts began to restart the General Services Building (GSB) Citrix Provisioning server environment in an attempt to restore service.
End: 2017/06/05 11:00 - Server environment restart was completed. The affected podium workstations were now able to boot OS images. Service was confirmed restored.
The image that is delivered to classroom podium workstations was inexplicably locked on one of the servers that is part of the GSB Citrix Provisioning environment. This error occurred at the Operating System level of the server, as a result the failover protection in the environment did not trigger.
Restarting the Citrix Provisioning servers resolved the issue.
A weekly maintenance restart of the Citrix Provisioning servers will be scheduled.
