storport WMI bug RRS feed

  • Question

  •  We add the WMI event notification mechanism into a storport miniport driver. As the WDK instruction refers, I set the WmiDataProvider to TRUE and initialized the WmiLib data structure in the HwStorFindAdapter() routine.
    Depending on the specification of the WMI mechanism designed by Microsoft in WDK, The first WMI command received from storport driver should be IRP_MN_REGINFO_EX(0x0b) to get the .bfm file name, Then the next WMI command is IRP_MN_QUERY_ALL_DATA(0x00). But in our driver, always the first WMI command received from storport driver is IRP_MN_QUERY_ALL_DATA 0x00.
    So We doubt
     there is a bug in the system's storport driver, it sends an incorrect WMI command.
    Our OS is windows server 2003 SP1, and the storport driver version is 5.2.3790.1830.
