The UIM inventory models created when Spectrum is integrated with UIM only include a reduced set of information, under Information tab. For instance "System resources" is not included as a subview.
This is expected, and working as designed.
The UIMHost model include just basic information extracted from UIM
Release : 10.0
Component : MITS SPECTRUM INTEGRATION
Only way to get all subviews on these models is to discover the device in Spectrum
Once modeled, the new model will be reconciled with the UIM model, like is shown on next example:
In the above example the Net-SNMP agent was installed on the Linux box, and then it was discovered in Spectrum. The new Net-SNMP model is then automatically reconciled with the UIMHost model.
