The SRBEX_DATA_PNP structure contains the request data for an extended plug and play (PNP) 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.
TypeData type indicator for the bidirectional extended SRB data structure. Set to SrbExDataTypePnp.
LengthLength of the data in this structure starting with the PnPSubFunction member. Set to SRBEX_DATA_PNP_LENGTH.
PnPSubFunctionThis member is not currently used. Set to 0.
ReservedThis member is reserved. Set to 0.
PnPActionThe plug and play action to perform. This member can have one of the following values:
| Value | Meaning |
|---|---|
| StorStartDevice 0x00 |
Start the device. |
| StorRemoveDevice 0x02 |
Remove the device. |
| StorStopDevice 0x04 |
Stop the device. |
| StorQueryCapabilities 0x09 |
Query the capabilities of the device. |
| StorQueryResourceRequirements 0x0B |
Query the resource requirements for the device. |
| StorFilterResourceRequirements 0x0D |
Filter the resource requirements for the device. |
| StorSupriseRemoval 0x17 |
Surprise Removal of the device. This value is available starting with Windows 7. |
SrbPnPFlagsIndicates that the PNP request is for the adapter if SRB_PNP_FLAGS_ADAPTER_REQUEST is set and that storage device address is reserved. Otherwise, SrbPnPFlags will be NULL, indicating that the request is for the storage device specified by an address at AddressOffset in the STORAGE_REQUEST_BLOCK structure.
Reserved1This member is reserved. Set to 0.
