Unable to cut, paste or delete UIM models in Spectrum
This is Functioning As Designed. It is as expected and devices discovered into Spectrum from UIM as part of integration will have the Copy & Cut options grayed out. This may be designed because when the next sync happens the model will be discovered again or probably to disallow users from pasting it to another topology view.
As a workaround, you can change the EditModeMask attribute value for the VMs to 224 using Attributes tab or Attribute Editor. Once you do that, you should be able to copy and paste the VM’s.
Also if we need the Cut option, we can set that value to 223 and getting the full privilege set it to 0. You can multi select the VMs in any view (Locater, topology, etc) and use "Attribute Editor" to write to all VMs in one action.
