Error description

  • v3.9-GA, FP1 & FP2 - platform independent.
    
    The 'Default Interface Ping' Poll definition has following
    filters under Interface filter tab against 'ncim.interfaces'
    table i.e. ipAddress IS NOT NULL ifAdminStatus = 'up'
    
    There could be many cases where we have valid IPAddress for an
    interface where ifAdminStatus is not populated. All such
    scenarios won't be polled by 'Interface Ping' policy.
    
    For e.g. A multi-net entity record won't be having ifAdmiStatus:
    
    Here is an excerpt of an multi-net interface:
    <snip>
    {
            EntityName='RouterA.ibm.com[ 0 [ 1023 ] ]';
            Address=['','','10.10.0.2'];
            EntityType=2;
            EntityOID='1.3.6.1.4.1.9.9.368.4.5';
            Status=1;
            IsActive=1;
            ExtraInfo={
                    m_IfIndex=1023;
                    m_IPData=[
                    {
                            m_IpAddress='10.10.0.2';
                            m_Protocol=1;
                            m_Subnet='10.10.0.0';
                            m_SubnetMask='255.255.252.0';
                            m_NetMaskBits=22;
                    },
                    {
                            m_IpAddress='10.20.30.2';
                            m_Protocol=1;
                            m_Subnet='10.20.30.0';
                            m_SubnetMask='255.255.255.0';
                            m_NetMaskBits=24;
                    }
                    ];
                   m_MultiNetList=['10.20.30.2','10.10.0.2'];
                   m_MultiNetSubnet=['10.20.30.0','10.10.0.0'];
                   m_MultiNetMask=['255.255.255.0','255.255.252.0'];
                   m_MultiNetProtocol=[1,1];
                   m_IpAddress='10.10.0.2';
                   m_AreaId='0.0.0.0';
                   m_OspfIfAdminStat=1;
                   m_OspfIfState=6;
                   m_OspfIfType=1;
    </snip>
    

Local fix

  • Remove Interface filter of ifAdminStatus = 'up'.
    Local fix: modify below file.
    $NCHOME/precision/scripts/sql/data/monitorDefaultPolicies.xml
    file in 3.9 and 4.1.
    
    
    FROM:
      ipAddress IS NOT NULL
                      ifAdminStatus = 'up'
    
    TO
         ipAddress IS NOT NULL
                      ifAdminStatus is NULL or ifAdminStatus = 'up'

Problem conclusion

  • Config file has been fixed and work around documented in local
    fix section.
    

Temporary fix

Comments

  • Please note that the solution involves the shipping of an
    updated xml file with the definitions of default policy
    definition to include an updated filter string. This however
    only gets read and reloaded upon a complete recreate of the
    database or upon the startup of a new domain.
    
    When upgrading to ITNM 3.9.0-ITNMIP-FP0004 this update has been
    included as part of the pre-installation steps for updating the
    database. A informational message will be issued following the
    running of that script to inform the user whether or not the
    update succeeded. Follow the information in the FP INSTALLATION
    README pertaining to this APAR should there be a WARNING issued.
    
    
    As a manual solution the recommended change is to update the
    interface filter under the Default Interface Ping policy
    definition.
    
    The change is to update the line
    
    ifAdminStatus = 'up'
    to
    ifAdminStatus is NULL or ifAdminStatus = 'up'
