Specifies the maximum number of bytes the HBA can transfer in a single transfer operation. The Storport driver initializes this member and miniport drivers must not modify it. This allows the miniport driver to maintain knowledge about the state of the adapter between Plug and Play PnP stops and restarts, possibly enabling the miniport driver to optimize it’s initialization procedure. Miniport drivers must not modify this value since this the default DMA addressing if a value for Dma64BitAddresses is not set. If additional space is needed in the LUN or SRB extensions to handle bit addresses, then appropriate adjustments must be made to this value before using it with routines such as StorPortGetUncachedExtension.

A miniport driver can reset this member syorport a lesser value if the HBA has more limited capabilities or to a greater value, indicating that the HBA has extended capabilities. The miniport driver sets this member to one of the following values to control mapping for SRB data buffer addresses. Follow these steps to install the driver.
Mniport drivers must not modify this member. By continuing to browse this site, you agree to this use. This member adjusts the initial queue depth for all LUNs on the adapter. After you remove the device from your computer and restart your system, Windows recognizes that it has been removed.
Windows does not provide any configurable Storport driver registry parameters for customization. The interrupt synchronization mode determines how the port driver synchronizes message signaled interrupts. If the driver is already installed and you want to install an updated driver, follow these steps. The storpogt size does not include any miniport driver-requested per-logical-unit storage. Specifies the number of buses controlled by the adapter.
The default is set to by Storport.
The Storport driver initializes this member to TRUEbecause its miniport drivers must support tagged-queuing. FC adapters are Plug and Play devices that are compatible with your computer. System minipotr features are shorport. Typically, this value is bounded by the value set for MaximumNumberOfTargets. Miniport drivers must not modify this value since this the default DMA addressing if a value for Dma64BitAddresses is not set.
The Storport driver initializes this member to TRUEbecause its miniport drivers must support auto-request sense. Miniports must not set this feature. The amount of time, in microseconds, to pause the adapter after a reset is detected. Specifies the number of target peripherals the adapter can control. It passes a pointer to the HBA-specific device extension in every call to a miniport driver. The Storport driver initializes this member and miniport drivers must not modify it. Specifies the maximum number of bytes the Ztorport can transfer in a single transfer operation.

We appreciate your feedback. Set this member to fv if the miniport driver does not maintain per-LU information for which it requires storage.
Storport set this to a default value of 20 for physical miniports and to for virtual miniports.
PORT_CONFIGURATION_INFORMATION structure (Windows Drivers)
Specifies the maximum number of logical units per target the HBA can control. This documentation is archived and is not being maintained. A miniport driver uses its device extension as storage for driver-determined host bus adapter HBA information. If Windows automatically installs the driver for the newly-added FC adapter upon startup, without prompting you for a selection for example, Windows Vista installed an Inbox drivertc to the “Updating the Existing Driver” section.
The miniport driver support bit addressing in a single 4GB region. QLogic Technical Support can be reached by the following methods:.
