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.
3. From the EFI Shell prompt, change to the CD drive.
shell> fs0: Enter
fs0:\>
4. Change to the directory that containscfggen.efi.
fs0:\> cd EFI\HP\TOOLS\NETWORK Enter
fs0: EFI\HP\TOOLS\NETWORK>
From this directory use cfggen.
CFGGEN Operation
cfggenis not case sensitive. You can enter cfggen commands and parameters in uppercase,
lowercase, or a mixture of the two. Use the following conventions in the command descriptions:
• Text in italics must be entered exactly as shown on the command line
• Text surrounded by <> must be replaced with a required parameter
• Text surrounded by [ ] may be replaced by an optional parameter
• Parameters surrounded by {} must be entered one or more times, as appropriate for the
executed command
• Do not enter the command line definition characters (<>, [ ], and {}) on the command line.
The cfggen command uses a command line interface.
Syntax: cfggen <controller #> <command> <parameters>
NOTE: The program name, controller number, command, and parameters fields must be separated
by the ASCII space character. The format of the parameters is command specific.
The program return value is returned to the user when the program exits. A value of 0 is returned
if the command is successful. Otherwise, a value of 1 is returned.
Rules for creating IM volumes and hot spare disks
The following rules apply when creating IM volumes and hot spare disks:
• All disks that are part of an IM volume or a hot spare for an IM volume must be on the same
SAS controller.
• IM volumes are supported.
• Only two IM volumes (plus a global hot spare) per controller can be created.
