After upgrading firmware on devices in CA Spectrum, Different Type Model (Modeltype Mismatch) alarms generate.

Products

Issue/Introduction

After upgrading a device(s) firmware, a Model type mismatch event and alarm are generated on the device model in CA Spectrum:

Sep 16, 2016 3:48:58 PM EDT<model name>  The model created (name - <model name>, type - <modeltype>) is not the same type as the device.System(Event 0x10006)

And alarm 0x10203:

DIFFERENT TYPE MODEL

Environment

Release: Any
Component:

Cause

The problem is caused by the firmware updating the system object id (sysoid) on the device to a sysoid that is either not certified or is certified as a "generic" modeltype in CA Spectrum.

When a model has a different modeltype than what is configured in the database, CA Spectrum will generate a "modeltype mismatch" alarm indicating the model does not match the type that is configured in the database.  

Resolution

This resolution can be applied if you confirm the devicetype has not changed.  It is used to remap the sysoid configuration in Spectrum from an "uncertified" modeltype to a "certified" modeltype.

You need to add the sysoid mapping for the modeltype to the CA Spectrum database.  Here are the steps to do that:

1.  Check the modeltype of the device by navigating to the devices model information view.  

2.  Note the modeltype name as well as the System Object ID

3.  Right click the device and select Utilities-Device Certification...

4.  The sysoid entry for this device should be highlighted.  If not, add it via the + icon.

5.  Set the Modeltype to the Modeltype you noted in step 2.

6.  Save the changes and close the Device Certification Gui.

7.  Manually clear the "Different Type Model" alarm.

 

Here is a specific example:

A device is modeled as a Rtr_Cisco

The firmware on the device is updated and that firmware changed the devices sysoid to be 1.3.6.1.4.1.9.1.1999.

This sysoid is not certified in CA Spectrum as can be validated here: https://netops-certification.broadcom.com/vendors(default-header:vendors)

Since the firmware update changed the sysoid to a non certified sysoid, CA Spectrum thinks the device modeltype should be either GnSNMPDev or GnCiscoDev.

However, you know that this is a Rtr_Cisco, and can be modeled as that enhanced modeltype.

Right click the Rtr_Cisco and go to Utilities-Device Certification...

Double click the entry for the 1.3.6.1.4.1.9.1.1999

Change the modeltype from GnCiscoDev to Rtr_Cisco.

Save the changes and close the gui.

Clear the Different Type Model alarm.
