In case if Instance Tree is not able to finish allocation due to Capacity Scope closed on the machine, and all it's instances supposed to end up on given machine, Operator needs to take proper actions.

Locate the Support Request

Locate the relevant Support Request related to the Instance Tree not being able to allocate. After navigating to Instance Tree the Operator will see a lot of Software Instances not allocated, which has Service Level Agreement XML set to computer_guid with value equal to Compute Node Ref. of the root instance.

Take actions

Navigate to the Compute Node of the root Software Instance, there go to the Capacity tab. Assert that Capacity Scope is Close.

Get value of Capacity and calculate 10% of it, remember this as Delta Capacity.

Repeat until the whole Instance Tree will be allocated:

  • to current Capacity add the Delta Capacity
  • wait until:
    • Compute Node Capacity Scope goes to Open
    • all of Software Instances get allocated
      • it might require resetting the Capacity value
  • observe if there are enough of Compute Node Partitions available on the Compute Node, if not, increase it by following how-to-XXX

When it's done wait for the Support Request have empty Current Monitor Status in Monitoring tab and close it.
