7.2.2 FPC IPMI interface
The FPC module on the IBM NeXtScale n1200 Enclosure supports IPMI over
LAN access. The FPC complies with IPMI v2.0 standard and uses extensions
and OEM IPMI commands to access FPC module-specific features. The IPMI
interface can be used to develop wrappers with which users can remotely
manage and configure multiple FPC modules at the same time.
By using the ipmitool command, you can manage and configure devices that
support IPMI. The ipmitool command provides an easy CLI to start IPMI
commands to a remote service processor through LAN. By using the tool, you
also can send raw commands that are not part of the IPMI v2.0 definition but are
vendor extensions to support certain specificities.
The FPC is compliant with IPMI v2.0, so default syntax and options can be used
to access the commands that are part of the IPMI v2.0 definition. For example, to
list the SEL, the following command can be used:
ipmitool -I lanplus -U USERID -P PASSW0RD -H 192.168.0.100 sel list
OEM IPMI command extensions require the use of the raw interface
ipmitool
provides. The syntax for such interface has the following format:
ipmitool -I lanplus -U USERID -P PASSW0RD \
-H 192.168.0.100 raw <netfn> <cmd> [<byte1>] [<byte2>] ...
Output is raw hexadecimal data that provides the completion code of the
operations and the resulting data. Input parameters and output values are
described next. “Examples” on page 209 provides some examples of how IPMI
commands are sent and how to process the output.
Many settings that are available at the web browser interface are provided as
IPMI commands. The following tables group the specific commands according to
their functionality:
򐂰 Table 7-4 on page 203 lists Power supply unit (PSU) IMPI commands
򐂰
Table 7-5 on page 204 lists Power capping IMPI commands
򐂰 Table 7-6 on page 205 lists Power redundancy IPMI commands
򐂰
Table 7-7 on page 205 lists Acoustic modes IPMI commands
򐂰 Table 7-8 on page 206 lists Power restore policy IPMI commands
Note: Cluster management software provides command line tools to use this
interface easier. However, some might not be implemented or you might want
to integrate IBM NeXtScale System into your own custom monitoring
infrastructure, so the IPMI commands are provided as reference.
