You experience problems when you use the Microsoft Storport storage driver for host bus adapter removable storage on a computer that is running Windows Server 2003

SYMPTOMS

When you use the Microsoft Storport storage driver for host bus adapter (HBA) removable storage, you may experience one or more of the following symptoms:

You cannot use a third-party driver to configure the storage device. This problem occurs because the operating system does not let the IOCTL_SCSI_GET_ADDRESS function run when the AddDevice routine is running.
There is no shutdown notification for a third-party Miniport driver so that the driver can complete all I/O operations before the shutdown occurs.
The boot enumeration flag is not set so that enumeration INQUIRY commands are not resent after startup for slower hardware.
The Storport miniport driver incorrectly links to standard C runtime libraries. Instead, the driver should link to the Storport.lib file. the Storport.lib file exports the memory manipulation functions that the miniport uses. However, the Storport.lib file does not export some of these functions. For example, the Storport.lib file does not export the memcmp function or the memcpy function. Therefore, the miniport driver must link to the Libcntpr.lib file. This update resolves this problem by exporting these functions. This specific fix is intended only for miniport developers.
When you use a program to import a snapshot image that was created by using the Volume Shadow Copy Service (VSS), a memory leak occurs. Specifically, a handle to the following registry subkey is leaked in the PortMapBuildLunEntry procedure of the SYSTEM process:
HKEY_LOCAL_MACHINE\HARDWARE\DEVICEMAP\Scsi\Scsi Port <w>\Scsi Bus <x>\Target Id <y>\Logical Unit Id <z>
Note In this registry subkey, w, x, y, and z are the respective identifiers for the Port, the Bus, the Target ID, and the Unit ID of the device.
There is no support for some revised SCSI specifications. These SCSI specifications pertain to the Inquiry command that is used to obtain VPD Page 83 device identification information.
The Storport driver ignores the status that is returned from a function that, in turn, returns the device state. If a device is deleted, the Storport driver may continue to process additional requests to that device. Because the return value is ignored, Storport processes the command for a device that is deleted. Therefore, a Stop error may occur.
After you install the latest version of Storport.Sys, you receive a 0xd1 DRIVER_IRQL_NOT_LESS_OR_EQUAL Stop error message.
Debug trace functionality has been reenabled. Debug trace functionality was removed in a previous Storport update.
The Storport driver uses the device descriptor in VPD page 0x83 to determine whether a device is unique. However, a device that is not ready may return descriptors that are not valid. The device may return spaces or zeros. When this issue occurs, the Storport driver may verify that a device has changed. Therefore, the device is removed and then added again. In this scenario, data corruption or a Stop error may occur. When this update is installed, the Storport driver will ignore any descriptor that contains a space or a zero.
If the miniport requests a callback on a computer that is running an Itanium-based version of Microsoft Windows Server 2003, the callback may occur during system shutdown. In this situation, a 0x9C MACHINE_CHECK_EXCEPTION Stop error may occur.

MORE INFORMATION

Technical support for x64-based versions of Microsoft Windows

Your hardware manufacturer provides technical support and assistance for x64-based versions of Windows. Your hardware manufacturer provides support because an x64-based version of Windows was included with your hardware. Your hardware manufacturer might have customized the installation of Windows with unique components. Unique components might include specific device drivers or might include optional settings to maximize the performance of the hardware. Microsoft will provide reasonable-effort assistance if you need technical help with your x64-based version of Windows. However, you might have to contact your manufacturer directly. Your manufacturer is best qualified to support the software that your manufacturer installed on the hardware.
