properly. To exit the utility, follow these steps:

only select the available options. The exit choices are as follows:
• Are you sure you want to exit?
• Cancel Exit
• Save changes and reboot

CFGGEN Utility
The cfggen utility is a command line utility that runs in the Linux, EFI, and Windows Pre-Installation
(WinPE) environments. It is a minimally interactive program that you execute from a command line
prompt, or a shell script. The results from invoking this utility are communicated through the program
status value that is returned when the program exits. Use the cfggen utility to create IM storage
configurations on SAS controllers. Some cfggen commands work only with SAS adaptors in the
EFI environment.
Starting CFGGEN
Thecfggenutility is located on the HP IPF Offline Diagnostic and Utilities CD. To use cfggen,
follow these steps:
1. Insert the CD into the drive.
2. Boot the system to the EFI Shell prompt.
