Table 5.15.: IPMI settings explained
Control Description
IPMI disabled Disables IPMI on LARA. This means that Status via IPMI and
Event Log via IPMI are not available and the power on/off and
reset functions don’t use IPMI rather than the ATX and the
reset cable connected from LARA to the motherboard.
BMC address The hexadecimal Baseboard Management Controller address,
which is needed for all communication types to the IPMI-
interface. Usually you can find this address in the BIOS of the
host system. The default and common value for this address is
20.
IPMI over Serial If your host system supports IPMI V1.5 and has an Intel EMP
(Emergency Management Port, usually COM2) connector, you
can connect IPMI through serial port 1 on LARA There are some
additional points to note:
ˆ
The EMP port must be set to ’Always enable’ and the
’Restricted Mode’ must be switched off.
ˆ
The BMC should accept a ’null username’ and a ’non-null
password’ account as login.
ˆ
Passwords are 4 - 16 characters long.
ˆ
A null modem cable is used for connection
IPMI over LAN You can connect the IPMI over a LAN connection too. The
prerequisite for this access type is a host system with IPMI V1.5
and a network adapter with a sideband connection to the BMC
(mostly on board). In the IPMI Settings, you must enter the
IP-address of this host system and the correct password for the
LAN connection.
You can also access other IPMI systems when you enter their IP
address.
Power Control
If IPMI is enabled, these functions are performed over IPMI requests. These requests may take a
few seconds.
If IPMI is disabled, the power control functions (power on, power off, reset) are performed over the
internal or external power control options.
Event Log via IPMI
The Event Log via IPMI accesses the SEL (System Event Log) repository and reads every entry
sequentially. The first time you use this function after starting LARA the complete repository has
to be read, what may take 1 or 2 minutes.
When all entries have been read, LARA displays the entries with their time, sensor and description
in accordance with the filter settings. You have the choice between several pre-settings (i.e. last
day, last week) or an exact declaration of the start and the end date.
