Source cim_schema_2.22.0Final-MOFs.zip To generate the OpenPegasus specific mofs used to load CIM server specific namespaces the script pegasus/mak/CreateDmtfSchema was used. Two manual updates needed to be made in the generated OpenPegasus mofs after running the script: In CIM_Core.mof added the line: #pragma include ("DMTF/Interop/CIM_Error.mof") at the top of all other includes. In CIM_System.mof added the line: #pragma include ("DMTF/User/CIM_Credential.mof") before the include of "DMTF/System/CIM_BIOSService.mof"
