I use the Unmanage Scheduling Utility to automatically set certain nodes to Unmanaged for nightly maintenance. If I want to set one Unmanage time on one of those nodes today to go Unmanaged tomorrow, It looses that Unmanage time when the nightly Unmanage happens via the Scheduling Utility.
Example: Node is set to go Unmanaged from 21:00 to 22:00 nightly via the Unmanage Scheduling Utility. I put in Unmanage time for the same node for 4:00 to 5:00 before going home. At 21:00 the Unmanage Scheduling Utility sets Unmanage time, over-riding the 4:00 to 5:00 time that was set earlier.
The Unmanage time is recorded in the nodes table in the database with a single field for start and end times. Orion cannot currently hold more than 1 Unmanage time record for a node.
I need a way to set multiple Unmanage times on a node so previous entries do not get over-rid.
