openipmicmd: An IPMI Command Interface


openipmicmd - An IPMI Command Interface


openipmicmd [-k entry-to-execute] <connection parms>


The openipmicmd program allows a user to execute direct IPMI commands. It can work with direct interface with the OpenIPMI driver or with IPMI LAN interfaces.


-k entry-to-execute
Execute a single command an exit.

<connection parms>
The parameters for the connection depend on the connection type. These are all described in openipmi_conparms (7)


Once up, you can execute commands in the user interface. Note that commands and responses are asynchronous, you issue a command and the interface returns immediately. When the response comes back, it will be dumped on your console. That's a little strange looking, but IPMI is asynchronous underneath. Note that the -k option is synchronous, it will wait for the response or a timeout before returning.

0f lun netfn cmd [data1 [data2 ...]]
Send a command to the BMC you are connected to.

channel [ipmb] IPMB-addr lun netfn [seq] cmd [data1 [data2 ...]]
Send a command to a device on the IPMB bus. The "ipmb" string is optional. The seq must be provided if the netfn is a response (an odd number). It must be the same sequence number that came in on the command in the "Command Sequence = seq" part of the command.

channel 00 IPMB-addr lun netfn cmd [data1 [data2 ...]]
Send a broadcast command to a device on the IPMB bus.

channel lan handle remote-swid local-swid lun netfn cmd [data1 [data ...]]
Send a command to a device over a LAN channel. Note that this not the same as a LAN connection. This sends a message through a local BMC to a remote system that is hooked up with a LAN connection.

test_lat count command
Executes the given commands (one of the previous commands) count times and gives the average time per command to execute. Note that "count" is hexadecimal.

Display some help.

regcmd netfn cmd
Register to receive the given command. If the driver receives an external command, it will print it out. This only works with system interface connections, it will not work on LAN connections.

unregcmd netfn cmd
Remove a command registration.


The asynchronous nature of the program can be annoying.
