Issue/Introduction
CA Spectrum device modeling is not doing a fully automated Device reconfiguration. Background here is to see the "Different Type Model" alarm indicating a device (model change) conflicting to a current device modeling. This is FAD.
To resolve this issue, CA Spectrum provide the ./Install-Tools/Postinstall -> NewMM.pl script.

Why is the "NewMM.pl" script failing to resolve the "Different Type Model" (PCause 0x10203) (EventType 0x10006 / The model created is not the same type as device)?
We see the script runs fine for many device reconfigurations.
The major background is, that for the NewMM.pl scripting/processing logic the type conversion is defined in pairs for "current model type" converted to "new model type".
So in case the current device model-type is not matching to the script declared paring (current_model-type : new_model-type) then script logic cannot convert this device model. Not any model-type pairing is declared by default.
Sample:
- initially the network device was modeled as "HubCat29xx" model-type - and this device hardware is now replaced by a current Cisco-Switch (C3850 class)
- the Spectrum logic can proper discover and create a device model for the C3850 - using the SwCiscoIOS model-type
- the NewMM.pl script does not cover a HubCat29xx to SwCiscoIOS conversion rule for i.e. 1.3.6.1.4.1.9.1.1745
Checking the NewMM.pl script for this (sample here is conversion pairing HubCat29xx to SwCiscoIOS):
grep "Destination mtype is SwCiscoIOS" NewMM.pl
# Source mtype is Rtr_Cisco / Destination mtype is SwCiscoIOS
# Source mtype is SwCat6xxx / Destination mtype is SwCiscoIOS
# Source mtype is SwCat35xx / Destination mtype is SwCiscoIOS
# Source mtype is SwCat4xxx / Destination mtype is SwCiscoIOS
# Source mtype is GnSNMPDev / Destination mtype is SwCiscoIOS
# Source mtype is GnSNMPDev / Destination mtype is SwCiscoIOS
grep HubCat29xx NewMM.pl | cut -c1-80
# Source mtype is Rtr_Cisco / Destination mtype is HubCat29xx
["HubCat29xx", "0x11c000f", 0,0, "$sysObjectID", "1.3.6. .......
# Source mtype is GnSNMPDev / Destination mtype is HubCat29xx
["HubCat29xx", "0x11c000f", 0,0, "$sysObjectID", "1.3.6. .......
This shows the checked NewMM.pl script does not support the conversion "HubCat29xx" to "SwCiscoIOS".

This shows the checked NewMM.pl script does not support the conversion "HubCat29xx" to "SwCiscoIOS".
Environment
This applies to all supported CA Spectrum platforms and CA Spectrum releases.
Resolution
CA Spectrum NewMM.pl script supports a "single" conversion pairing mode per command-line option "-m".
Documentation https://docops.ca.com/ca-spectrum/10-2-3/en/managing-network/certifications/customizing-identification-with-device-certification/change-the-model-type-for-a-single-device-type-using-a-script
Running the NewMM.pl script in single-device mode is the solution to address non_defined device model-type pairing for the NewMM.pl script.
The NewMM.pl script could be used to do a manual conversion in case:
- the current CA Spectrum install will support the device model-type assignment per auto-discovery logic out of the box
(so please do a single device discovery by "IP" and verify the default model-type assignment.)
- the Device SysObjID is supported and listed in the "Device Certification" Utility
Now make use of CA Spectrum install owner - while having the SpectroSERVER running - to run the script with "-m"
./Install-Tools/Postinstall/NewMM.pl -m
In the upcoming dialog update the "device model-type" pairing and SysObjID as appropriate. Below find additional information for the above sample device problem (obsolete Model-Type HubCat29xx - new targeted Model-Type SwCiscoIOS for device models with SysObjID 1.3.6.1.4.1.9.1.1745)
You may have to rerun the NewMM.pl script with option "-m" then for further model-type conversions.
Each run will do so for one single criteria set: current_model-type : targeted_new_model-type : SysObjID

NewMM.pl is running using custom conversion criteria. To use out-of-the-box conversion
criteria, run NewMM.pl without the `-m' option.
