An updated Storport storage driver (version 5.2.3790.2630) is available for Windows Server 2003 (912944)

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:

Symptom 1
The Storport storage driver incorrectly handles inquiry page 0x83 data. Therefore, the driver does not detect that a device has changed. You may eventually receive a Stop error message on a blue screen.

Note For more information about when Symptom 1 occurs, see the "More Information" section.
Symptom 2
The Storport storage driver does not detect a new device that replaces a device that has been removed.

Note For more information about when Symptom 2 occurs, see the "More Information" section.
Symptom 3
When you remove a cable from one of the HBA paths in a Microsoft Multipath I/O (MPIO) environment, a cleanup of the logical unit numbers (LUNs) that are associated with that HBA path may not occur. When a subsequent operation occurs to access the disconnected path, the computer may stop responding.
Symptom 4
A memory leak may occur when a new inquiry operation causes a new allocation to be created. The allocation is not freed, and a leak of 512 bytes per inquiry occurs. This leak can cause non-paged pool memory to become exhausted. When a memory leaks occurs, you may receive various error messages. Additionally, the computer may perform poorly or stop responding.

MORE INFORMATION

Symptom 1 scenario

The Storport storage driver incorrectly handles inquiry page 0x83 data. Therefore, the driver does not detect that a device has changed. The problem occurs in the following scenario:

Disk A is exposed as LUN 1 TARGET 1 BUS 1.
Disk A is replaced by Disk B.
Disk B also uses LUN 1 TARGET 1 BUS 1.

Symptom 2 scenario

The Storport storage driver does not detect a new device that replaces a device that has been removed. This problem occurs in the following scenario:

Disk A is replaced by Disk B.
Disk B uses the same LUN TARGET and BUS ID as Disk A used.
The Storport storage driver detects that Disk A has been removed. However, the driver may not detect Disk B until another rescan occurs.

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.
