Upgrade Scenarios and Mapping Behavior

casp1031
Go through the following scenarios for the expected behavior of models in Spectrum after you complete configuring and enabling multi-tenancy.
Upgrade Scenarios
Enabling Multi-tenancy after upgrading to 10.2.2, from a CA Spectrum 10.2.1 DSS environment which is already integrated with CA UIM 
Scenario:
I am currently on CA Spectrum 10.2.1 and the the bidirectional integration with CA UIM (with VMware and Server management) is enabled in my DSS environment. What happens to the models that already exist in my Spectrum environment in specific landscapes in the Universe view when I configure and enable Multi-tenancy?
Expected Behavior:
 After you have successfully upgraded to CA Spectrum 10.2.2, ensure that all the models exist in the selected Landscape.
  1. Map CA Spectrum landscapes (or Landscape + SDC) to CA UIM Origins from the
    Landscape Mapping
    section and enabled multi-tenancy from the spectrumgtw probe Admin Console. The following behavior is expected:
    • If the models already exist in the mapped landscape, then they should be retained and ensure that the UIMOrigin (0x1337f) attribute has correct value. 
    • If the models exist in different landscape, they should be removed and modeled in the new landscape which is mapped to the origin. 
Enabling multi-tenancy on a new CA Spectrum 10.2.2 DSS setup (Install 10.2 and upgrade to 10.2.2)
Scenario:
I have a new 10.2.2 setup, after I upgraded from CA Spectrum 10.2.2 from CA Spectrum 10.2.
Expected Behavior
: After you complete the upgrade to 10.2.2. from 10.2, validate the modeling behavior before and after receiving the mapping.
  1. Integrate Spectrum 10.2.2 with UIM [In DSS].
  2. Enable Server and vmware management for a selected landscape. 
  3. Map CA Spectrum landscapes (or Landscape + SDC) to CA UIM Origins from the 
    Landscape Mapping
     section and enabled multi-tenancy from the spectrumgtw probe Admin Console. 
    The following behavior is expected:
    • If the models already exist in the mapped landscape then they should be retained and ensure that the origin attribute has correct value. 
    • If the models exist in different landscape, they should be removed and modeled in the new landscape which is mapped to the origin.
If the CA Spectrum-CA UIM integration via spectrumgtw probe is already in place, but some of the device models have origin not mapped to a landscape, the related models (coming from from the origin that is not mapped) are not removed from the Landscape they are currently modeled in. You need manually remove those models.
Mapping Behavior
Points to note:
  • Once the Origin to Landscape mapping is in place, any new entities coming in from CA UIM (with an origin that is not mapped to a landscape), are not modeled in CA Spectrum. Alarms are not be stopped but are asserted to Main Location Server's UIM EventAdmin model. Existing alarms will remain with previous EventAdmin, even after multi-tenancy is enabled. If you do not need the models, you have to remove the models manually.
  • If the origin gets mapped to new landscape, then the existing models corresponding to that origin are deleted from the old landscape and are modeled in the new landscape.
  • If a new SDC is specified for an origin, in the origin to landscape map, then all the entities are associated to that SDC. Similarly if you change the mapped SDC all entities are associated with the SDC most recently mapped. 
  • If Origin to Landscape mapping is removed, corresponding device models are not removed from CA Spectrum. If you do not need the models, you have to remove the models manually.
  • When a new configuration of Origin to Landscape mapping is added, device models of that origin are synced during the next inventory full synchronization, after the map update is received by CA Spectrum.
  • Till CA Spectrum 10.2.1, you could see all the VMware Datacenters in the
    UIM Manager
