Using the CFGGEN IR Configuration
Utility
This Chapter describes how to use the CFGGEN IR Configuration Utility to create
Integrated Mirroring (IM), Integrated Mirroring Enhanced (IME), and Integrated Striping
(IS) volumes on SAS controllers. CFGGEN is a command line utility that runs in the
DOS, Linux, EFI, and Windows Pre-Installation (WinPE) environments. CFGGEN is a
minimally interactive program that can be executed from a command line prompt or a
shell script.
9-1 Hardware and Software Requirements
The CFGGEN IR Configuration Utility runs on any Intel IA-32 or IA64 compatible
platform. It works with storage devices that are compliant with existing SCSI standards.
CFGGEN supports the LSISAS1064/1064E, LSISAS1068/1068E, and LSISAS1078 LSI
SAS controller chips.
CFGGEN runs in the following operating environments:
• DOS – CFGGEN runs in any environment that is fully DOS compatible and has at
least 640-KB of memory. The system BIOS must support 32-bit BIOS services,
including the PCI BIOS services. CFGGEN uses these services to locate the
controller and its interface registers. CFGGEN must be able to directly access the
controller chip’s interface registers.
• EFI – CFGGEN runs in any environment that is fully EFI compatible.
• Linux – CFGGEN is a statically linked Linux application. Static linking prevents any
library version compatibility problems that might stop CFGGEN from working with a
specific release or distribution of Linux. Version 3.02.04 or newer of the LSI mptlinux
driver must be installed on the system. The required modules include mptbase.o,
mptscsih.o, and mptctl.o.
NOTE: CFGGEN is intended for use only in the manufacturing environment.
End users can use the BIOS-based configuration utility to create IM, IME, and
IS volumes. (See Section 7-7: "Creating IM and IME Volumes" on page 7-6 and
Section 8-7: "Creating IS Volumes" on page 8-4)
NOTE: You cannot run CFGGEN in a virtual DOS window from within Windows.
