Issue/Introduction

We have physically removed a stack member from a Chassis Switch and the data no longer shows up in the mib, however when we run a reconfigure device, Spectrum creates a critical alarm on the missing stack.

We do not want to destroy and rediscover this model, how can we remove this stack member from Spectrum and no longer have a critical alarm for stack down?

Environment

Spectrum ANY

Resolution

Please make sure that you have a current SSdb save just in case.  Then proceed with the following:

 

1. Verify that the model handle of the stack is the correct stack that you removed.

2. Once you have the model handle, you can connect to the SpectroSERVER that has the switch modeled on and enter CLI by cd into $SPECROOT/vnmsh

3. Once you are in $SPECROOT/vnmsh type 

./connect

to connect to CLI.

4. Issue the command to destroy the unwanted stack model. There will be a final confirmation that you can verify the model handle and model name before typing Y to destroy.

[spectrum@SS vnmsh]$ ./destroy model mh=0x11a8af

     Following Model will be destroyed :

     Model_Handle          ->      0x11a8af
     Model_Type_Handle      ->      0x104ba
     Model_Name          ->      #####-#####-stack_4
     Model_Type_Name      ->      Chassis

destroy model: are you sure ? y
destroy model: successful
[spectrum@SS vnmsh]$

5. Now when you run a reconfigure model, the unwanted stack model will no longer alarm because the model has been destroyed from Spectrum.
