StorPortPauseDevice routine

The StorPortPauseDevice routine pauses a specific logical unit device for the specified period of time.

Syntax


STORPORT_API BOOLEAN StorPortPauseDevice(
  _In_  PVOID HwDeviceExtension,
  _In_  UCHAR PathId,
  _In_  UCHAR TargetId,
  _In_  UCHAR Lun,
  _In_  ULONG TimeOut
);

Parameters

HwDeviceExtension [in]

A pointer to the hardware device extension. This is a per HBA storage area that the port driver allocates and initializes on behalf of the miniport driver. Miniport drivers usually store HBA-specific information in this extension, such as the state of the HBA and the mapped access ranges for the HBA. This area is available to the miniport driver immediately after the miniport driver calls StorPortInitialize. The port driver frees this memory when it removes the device.

PathId [in]

Identifies the SCSI bus.

TargetId [in]

Identifies the target controller or device on the bus.

Lun [in]

Identifies the logical unit number of the target device.

TimeOut [in]

Contains the interval of time that the device is to be paused, in seconds.

Return value

StorPortPauseDevice returns TRUE if the miniport driver succeeded in pausing the device, FALSE if not.

Remarks

When the time-out expires, I/O requests to the device will be resumed.

Requirements

Header

Storport.h (include Storport.h)

Library
