Intel Intel NetStructure Single Board Computer Reference Script referencecfg, LAN Parameters

MPCBL0010 SBC—Serial Over LAN (SOL)

11.7Reference Script (reference_cfg)

11.7.1SOL Configuration Reference Script (reference_cfg)

The reference script can run with no special setup. The script uses built-in bash commands as well as grep and awk. The environment in which the script runs must have bash installed at /bin/bash (or a symbolic link at that location), and must include grep and awk in the path.

The reference script is implemented as two separate bash files: reference_cfg, which contains the necessary IPMI commands, and reference_func, a library of supporting functions. When reference_cfg runs, it looks for the library in the following paths in the order listed:

1.the current working directory

2./usr/lib/sbcutils

3./home/scripts

If reference_cfg cannot find the library in any of these locations, it terminates with an error message.

When running the reference script on a remote node over RMCP via a shelf manager RMCP to IPMB, bridging must be enabled on the shelf manager. In the case of the Intel NetStructure MPCMM0001/0002 Chassis Management Module, the following command enables RMCP:

# cmmset -d rmcpenable -v 1

RMCP and KCS communication requires the OpenIPMI application library, version 1.4 or later. KCS communication further requires the OpenIPMI driver.

11.7.2Default Behavior

To configure a blade for SOL communications, many configuration parameters are required (for example, user information, channel parameters, LAN parameters, SOL parameters). Most of the values used for configuration appear as hard-coded default values.

11.7.3SOL User Information

SBCs from Intel implement four different users, User1 through User4. User1 has a null username that is not editable. The script configures User2 as specifically enabled for SOL payloads.

The user name is “solusername”, zero-padded to a length of 16 bytes as per the IPMI

2.0 specification. The password is “soluserpassword”, zero-padded to 20 bytes as per the IPMI 2.0 extension.

11.7.4LAN Parameters

The reference script configures IPMI channel 1. The IPMI channel number used by reference_cfg can be changed to any IPMI LAN channel supported by the target SBC.

The configured channel must be a base interface, not a fabric interface. On the MPCBL0010 SBC, IPMC channel 1 corresponds to the Ethernet interface eth1.

Since reference_cfg uses IPMI channel 1, for any SBC, eth0 will be routed to a switch in slot 7 (This may vary with different chassis implementations.)
