DASL compilation fails for Cisco ACS device class available in default package directory

Products

• VMware Smart Assurance

Issue/Introduction

Symptoms:

When user restarts or compiles packages in NCM, Cisco ACS fails to compile though there is no custompackage/customization entry.
Error will be thrown on discovery.inc file under $VOYENCE_HOME/package/ddt and devCiscoACS.dasl located under $VOYENCE_HOME/package/cisco/acs.

Error seen in autodisc.log and in daslcompile.log:

Impact/Risks:

• Unable to discovery new Cisco ACS device.
• Any modification made to other device class in custompackage is not taken into consideration as DASL compile failed with error.

Environment

NCM - 10.1.x

Cause

Standard library file (stdlib.inc) is called after discovery.inc which is causing failure in compilation of drivers.

Resolution

• Create $VOYENCE_HOME/custompackage/cisco/acs directory; if it is not available already.
• Copy devCiscoACS.dasl from $VOYENCE_HOME/package/cisco/acs to $VOYENCE_HOME/custompackage/cisco/acs
• Open $VOYENCE_HOME/custompackage/cisco/acs/devCiscoACS.dasl 

Change included file sequence from :

#include "ddt/discovery.inc"
#include "stdlib/stdlib.inc"
#include "ddt/cli.inc"
#include "ddt/identity.inc"
#include "ddt/systemProperties.inc"
#include "ddt/fileSystem.inc"
#include "ddt/miscunits.inc"
#include "ddt/pull.inc"
#include "ddt/push.inc"
#include "ddt/password.inc"
#include "ddt/hwinv.inc"
#include "ddt/miscentries.inc"
#include "cisco/acs/quickcmds.inc"

To

#include "stdlib/stdlib.inc"
#include "ddt/cli.inc"
#include "ddt/identity.inc"
#include "ddt/systemProperties.inc"
#include "ddt/discovery.inc"
#include "ddt/fileSystem.inc"
#include "ddt/miscunits.inc"
#include "ddt/pull.inc"
#include "ddt/push.inc"
#include "ddt/password.inc"
#include "ddt/hwinv.inc"
#include "ddt/miscentries.inc"
#include "cisco/acs/quickcmds.inc"

• Save and close the file.
• Restart vcmaster service.
  
  
  Compile dasl now and confirm success.
  
  NOTE: $VOYENCE_HOME is path where NCM is installed.
