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 operating 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)
SAS2XP86 – SAS Gen 2 (ScsiPort – Windows XP x86 only)
[NOTE: SAS2XP86 replaced LSI_GEN2 starting Phase 11]
LSI_SAS – SAS Gen 1
LSI_SCSI – Parallel SCSI
LSI_FC – Fibre Channel
LSI_SSS – Warhawk (PCIe Solid State Storage Card)
MEGASAS2 – MegaSAS2 (MegaRAID Driver)
PERCSAS2 – PercSAS2 (MegaRAID Driver)
SRAMPT – 3rd Party Supported Driver
SRAMPT2 – 3rd Party Supported Driver
SRAMPT3 – 3rd Party Supported Driver
SRATAPE – 3rd Party Supported Driver
SRATAPE2 – 3rd Party Supported Driver
SRATAPE3 – 3rd Party Supported Driver
Drivers not covered include:
SYM_MPI – Legacy
2.3 Configuration Parameters
WDCFG allows manipulation over a variety 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.
