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 cfggencommands 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 utility 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 of0is returned if
the command is successful. Otherwise, a value of1is 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.
• An IM array must have exactly two disks.
• A hot spare disk cannot be created without at least one IM volume already created.
• The utility does not allow adding a hot spare disk of type different from disk types in any of
the volume.
• With the AUTO command, all drives used are the same type as the first available disk found,
and the size is limited to the size of the smallest disk.
CFGGEN Commands
Using the CREATE Command
The CREATE command creates IM volumes on the SAS controller. Firmware and hardware limitations
for this family of cards limit the number of configurations that are possible.
Syntax
cfggen <controller #> create <volume type> <size> [qsync] [noprompt]
Parameters
<volume type> Volume type for the volume to be created. Valid value is IM.
