SRBEX_DATA_WMI structure (storport.h)

The SRBEX_DATA_WMI structure contains the request data for an extended WMI SRB.

Note  The SCSI port driver and SCSI miniport driver models may be altered or unavailable in the future. Instead, we recommend using the Storport driver and Storport miniport driver models.

 

Syntax

typedef struct _SRBEX_DATA_WMI {
  SRBEXDATATYPE       Type;
  ULONG               Length;
  UCHAR               WMISubFunction;

  UCHAR               Reserved[2];
  ULONG               Reserved1;
  PVOID POINTER_ALIGN DataPath;
} SRBEX_DATA_WMI, *PSRBEX_DATA_WMI;

Members

Type

Data type indicator for the bidirectional extended SRB data structure. Set to SrbExDataTypeWmi.

Length

Length of the data in this structure starting with the WMISubFunction member. Set to SRBEX_DATA_WMI_LENGTH.

WMISubFunction

Indicates the WMI action to be performed. The subfunction value corresponds to the WMI minor IRP number that identifies the WMI operation.

WMIFlags

Indicates that the WMI request is for the adapter if SRB_WMI_FLAGS_ADAPTER_REQUEST is set and that storage device address is reserved. Otherwise, WMIFlags will be NULL, indicating that the request is for the storage device specified by an address at AddressOffset in the STORAGE_REQUEST_BLOCK structure.

Reserved[2]

This member is reserved. Contains zeros.

Reserved1

This member is reserved. Set to 0.

DataPath

Specifies the WMI data path for this request.
