Customer stated that for maintenance in USM, when they created an ad hoc maintenance schedule, e.g., 'Once Only,' they used to be able to see the schedule details displayed in USM but after upgrading to UIM v9.02, the details no longer display. Instead, after the schedule window has passed, it shows “No Maintenance Scheduled.”
This was reproduced in the Lab - and details of the schedule are no longer displayed in UIM 9.x versions.
This unexpected change/outcome is most likely due to a few changes introduced in UIM v9.02 for performance improvement. DEV/Sustaining Engineering suggest opening an enhancement request (Idea) and the Product Management team will take it under consideration.https://community.broadcom.com/participate/ideation-home?IdeationConfigurationKey=275c031b-44b4-489f-91c7-0c83235f2d8c
In the meantime, please try to workaround the issue if possible by creating ad hoc schedules (once only), that contain more helpful/descriptive data in the name.
