StorPortNvmeIceIoStart function (storport.h)

The StorPortNvmeIceIoStart function initiates an NVMe ICE (instant cryptographic erase) I/O operation.

Syntax

ULONG StorPortNvmeIceIoStart(
  PVOID               HwDeviceExtension,
  PSCSI_REQUEST_BLOCK Srb,
  ULONG               LbaCount,
  ULONG               PrpCount,
  PULONGLONG          Prp1,
  PULONGLONG          Prp2,
  PULONGLONG          PrpList
);

Parameters

HwDeviceExtension

[in] A pointer to the hardware device extension. This is a per HBA (Host Bus Adapter) context area provided by the miniport driver. The miniport driver can store HBA-specific information here.

Srb

[in] A pointer to a SCSI request block. This structure represents a single I/O request.

LbaCount

[in] The number of logical block addresses (LBAs) to be transferred.

PrpCount

[in] The number of physical region pages (PRPs) to be transferred.

Prp1

[in/out] A pointer to the first PRP, used in NVMe to describe the physical memory locations involved in the data transfer.

Prp2

[in/out] A pointer to the second PRP, used in NVMe to describe the physical memory locations involved in the data transfer.

PrpList

[in/out] A pointer to a list of additional PRPs.

Return value

StorPortNvmeIceIoStart returns STOR_STATUS_SUCCESS if the operation is successful. Otherwise, it returns a STOR_STATUS value such as one of the following:

Return code Description
STOR_STATUS_NOT_IMPLEMENTED This function isn't implemented on the active operating system.
STOR_STATUS_INVALID_PARAMETER One of the parameters is invalid.
