SCOM discovery issue.

Hi,

 

 

I am trying to get SCOM to discover my Big-IP boxes, 3 work ok and 3 do not and I get

 

 

Execute device discovery:Failure

 

Failure Message: F5Networks.Protocols.iControl.iControlException: The server committed a protocol violation. Section=ResponseHeader Detail=CR must be followed by LF

 

 

The 3 that do not work are sitting behind a firewall but my firewall guy assures me that all the necessary ports are open. These boxes were discovered okay by the TEST SCOM box, and the firewall rules are supposedly the same for the PROD SCOM box.

 

 

Anyone got any ideas?

 

Thanks.

 

Rab.

    Hi Rab,

     

     

    It looks like it could be a couple of things. First of all, are the versions of all 6 Big-IP the same? If/not what versions are each of the Big-IP, specifically the ones in question. Also, can you find out if the firewall is rewriting or analyzing the headers in any way?

     

     

    Thanks,

     

    Dave

    Hi Dave,

     

    all 6 Big-Ip boxes are BIG-IP Version 10.0.1 402.16 Engineering Hotfix HF4 Edition.

     

    From my firewall guy -

     

    Q. Also, can you find out if the firewall is rewriting or analyzing the headers in any way?

     

    A. No, doesn't do anything of the sort.

     

     

    Thanks.

     

    Rab.
