The LAN parameters will be saved and remembered by the MCH. This is important for the us-
age of IOL after switching on the MCH without having a connection to the CLI.
In the following the free Linux tool 'ipmitool' (version >= 1.8.10) is used to run IOL and SOL. For
additional information to possible parameters and functionality please refer to the related online
help, man page etc. of 'ipmitool'.
5.2.1 IPMI Over LAN (IOL) for Invoking IPMI Commands
IPMI Over LAN allows to invoke IPMI commands by using the Ethernet connection to the
MCH's management port. More than one IOL connection may be active at one time.
For the usage of SOL only the LAN parameters must be set and activated. Please refer to the
above.
A first user command after LAN set up might be similar to the following:
This command returns the standard information about the running MCH firmware. The target
is the Module Management Controller of the MCH.
If access to the Module Management Controller of an AMC module in the rack is required, the
following parameters must be added to the command above before 'mc info':
where ’nn’ is the address of the AMC module on the IPMB-L bus which is addressed by ’-b 7’.
For slots 1..6, ’0xnn’ is 0x72..0x7C.
If access to the Module Management Controller of a module on the IPMB-0 bus is required (e.g.
a standard power module), the following parameters must be added, e.g. to the command
above before 'mc info':
where ’nn’ is the IPMB-0 address, e.g. of the standard power module. The address of the first
standard power module is 0xC2. The address of the first standard cooling unit is 0xA8.
Hint: ’ipmitool’ offers similar commands to display and set LAN parameters ('…lan set 1…',
'…lan print 1').
5.2.2 Serial Over LAN (SOL) for CLI over LAN
For Serial Over LAN (SOL) the data exchange protocol being used by IOL is extended to trans-
port any serial data instead of IPMI data (RMCP+ protocol).
If SOL is activated for the MCH, then received SOL data is transferred internally to the MCH's
serial Command Line Interface (CLI). The response data of the CLI then is sent back via SOL.
This allows running the CLI via Ethernet thus saving a physical serial connection between a
terminal and the MCH's CLI.
