1. Introduction
This document serves as the User Guide for the LSI Windows Driver Configuration Utility (wdcfg).
Wdcfg provides run-time control over various configuration parameters which configure LSI host storage
drivers used on the Windows operating system.

2. Scope
2.1 Operating System Versions
The Microsoft requirement (DEVFUND-0046) established the need for a command line (CLI) utility to
configure drivers installed on Windows Server versions of the OS. While the utility is required on all OS
versions beginning with Windows Vista / Windows Server 2008 and newer, it specifically targeted those
versions that can run in Server Core mode (no GUI), hence the need for a CLI based utility.
Supported versions of the Windows operationg system are listed below.
Windows Vista
Windows Server 2008
Windows 7
Windows Server 2008 R2
Future versions of Windows
2.2 Drivers Supported
Specific drivers covered include:
LSI_SAS2 – SAS Gen 2
LSI_GEN2 – SAS Gen 2 (ScsiPort – Windows XP x86 only)
LSI_SAS – SAS Gen 1
LSI_SCSI – Parallel SCSI
LSI_FC – Fibre Channel
LSI_SSS – Warhawk (PCIe Solid State Storage Card)
SRAMPT – 3rd Party Supported Driver
SRATAPE – 3rd Party Supported Driver
Drivers not covered include:
SYM_MPI – Legacy
2.3 Configuration Parameters
Wdcfg allows manipulation over a varfiety of driver configuration parameters. Note that some
parameters can have a seriously adverse affect upon system operation if set incorrectly, so the user is
cautioned to exercise care when using WDCFG.
All configuration parameters controllable using wdcfg are documented in the utilities data file,
DriverConfigParam.def. Detailed documentation on all supported configuration parameters is available
from this data file using the WDCFG Help option, documented herein. This data file should never be
edited directly, as failure of the configuration system can result. It is safe to view via the WDCFG Help
option.
Not all parameters apply to all supported drivers. For example, SAS specific parameters do not apply to
the Fibre Channel driver or to the SCSI driver. See the WDCFG Help option for full documentation on
all supported parameters, including per-driver applicability.
