ipmi_sim_cmd(5) IPMI LAN Simulator commands ipmi_sim_cmd(5)

DESCRIPTION
The ipmi_sim emulation is set up using these commands. They can be read from a command file,
run from the command line, or executed inside the simulator after it is started.

This may be a little confusing, but the network interfaces are configured by the ipmi_lan
configuration file, and the various management controllers, sensors, etc. are specified using
this file. Plus, this can be used to configure the simulator after it is up, set sensor val‐
ues, inject events, and things of that nature.

GENERAL COMMANDS
Blank lines and lines starting with `#' are ignored. Long lines may be broken up by putting
a '´ at the end of the line to be continued.

quit Exit the simulator

include "file"
Include the given file.

define name "value"

Define the given name as a variable with the given value. This variable may be used
later by doing $name. This cannot be used in quotes, but quotes may be broken up and
the variable put between them. For instance, if you say:

define MCNUM "40"

you can use it later as in

mc_add $MCNUM 1 no-device-sdrs 00 00 00 0xc9 0x009000 0x0002

sensor_add $MCNUM 0 21 12 0x6f poll 1000 file "/sys/dev/sens1-"$MCNUM"-1"

sleep time
Pause the command interface for the given number of seconds. This does not affect the
execution of the simulator.

debug options
Set the debugging output. Valid options are:

msg Dump messages.

raw Dump raw I/O

Entering nothing turns of debugging.

read_cmds filename
Execute the commands in the given file.

MC COMMANDS
mc_add IPMBAddress DeviceID HasDeviceSDRs DeviceRevision MajorFWRev MinorFWRev DeviceSupport
ManufacturerID ProductID
Add an MC to the simulator. All values are hexadecimal. These are mostly values for
the ``Get Device ID'' command, see the spec for details. Note that the MC is not en‐
abled after being added, you must add it.

Note that some of these values control the capabilities of the MC. For instance, Has‐
DeviceSDRs sets whether device SDR repository commands will work.

You may use has-device-sdrs or no-device-sdrs in the HasDeviceSDRs field.

mc_add_fru_data mc-addr DeviceID FRUSize (data [byte1 [byte2 [...]]] | file offset filename)
Set the FRU data for a given MC and device id. Data may be supplied directly here, or
it may be given as a file. The offset is the start from the beginning of the file
where the data is kept.

mc_dump_fru_data mc-addr DeviceID
Dump the FRU data for a given MC and device id.

mc_delete mc-addr
Remove the MC from the system.

mc_disable mc-addr
Disable the MC, but don't remove it.

mc_enable mc-addr
Enable the given MC.

mc_setbmc mc-addr
Set the BMC's address.

mc_set_guid mc-addr guid
Set the GUID value. The guid may be a string (in quotes) or a hexadecimal string.

sel_enable mc-addr max-entries flags
Enable the System Event Log on the given MC. The flags is a byte this is returned
from the ``Get SEL Info'' command; it controls various aspects of the SEL. See the
spec for details.

sel_add mc-addr RecordType byte1 byte2 ... byte13
Add an entry to the MC's SEL.

main_sdr_add mc-addr byte1 [byte2 [...]]
Add an entry to the main SDR of the MC.

device_sdr_add mc-addr LUN byte1 [byte2 [...]]
Add an entry to the device SDR of the MC.

SENSOR COMMANDS
sensor_add mc-addr LUN sensor-num sensor-type event-reading-code [poll poll_rate poll_type
poll_type_options] [event-only]

Add a sensor to the given MC and LUN. The type of sensor is set by the event reading
code.

If poll is specified, then the sensor will be polled for data. Only the file poll
type is currently supported. The value is a number read from a file. It has the fol‐
lowing options, all optional:

div=val will divide the read value by the given number. This is done after the multi‐
ply operation.

mult=val will multiply the read value by the given number. This is done after the
subtraction.

sub=val will subtract the value by the given number. This is done after the mask.

mask=val will mask (bitwise and) the value by the given number.

base=value Specify the base of the value read from the file. By default this is zero,
meaning "C" conventions are used.

initstate=value sets what the event state is initially set to. This is useful for
discrete sensors with bits that should normally be set to "1", like a presence bit, to
keep the program from issuing an event every time the program starts.

raw specifies that the data from the file is a raw value. Only length bytes are read
from offset.

ascii specifies that the data from the file is in ASCII. This is the default. The
offset value is used, but no the length.

length=val specifies the length of the data to read from the file. The maximum value
is 4,and this is only used for raw data.

depends=<mc_addr>,<lun>,<sensor_number>,<bit> specifies a discrete sensor bit that
must be set to 1 for the sensor to be active. Generally, you use the presence bit of
a sensor to mark whether other sensors on the device are actually present. Each of
the other sensors would have one of these pointing to the presence bit.

event-only specifies that the sensor will not be readable, it will only generate
events (specified with a type 3 SDR).

sensor_set_bit mc-addr LUN sensor-num bit-to-set bit-value generate-event
Set the given bit to bit-value (0 or 1) for the sensor by bit number, either the
threshold for analog or the discrete sensor bit. If generate-event is non-zero and
the sensor has events enabled for that bit, then generate an event.

sensor_set_bit_clr_rest mc-addr LUN sensor-num bit-to-set bit-value generate-event
Like sensor_set_bit, but automatically clears all other bits.

sensor_set_value mc-addr LUN sensor-num value generate-event
Set the byte value for an analog sensor. If the sensor exceeds a threshold, the sen‐
sor has events enabled, and generate-event is non-zero, then generate an event for the
condition.

sensor_set_hysteresis mc-addr LUN sensor-num support positive negative
Set the hysteresis capabilities of the sensor. It must be an analog sensor. The sup‐
port value is the hysteresis capability, the same as the hysteresis support value in
the sensor SDR. The positive and negative hysteresis values are also set by this com‐
mand.

The support value may also be none, readable, settable, or fixed instead of the num‐
bers.

sensor_set_threshold mc-addr LUN sensor-num threshold-support threshold-enabled [value5
[value4 [... [value0]]]]

Set the threshold support for a sensor. It must be an analog sensor. The threshold-
support value is the same as the threshold access support value in the sensor SDR.
The threshold-enabled values is a string of ``0'' and ``1'' characters that enable the
6 corresponding thresholds; the rightmost value is value 0, the leftmost is value 5.
Optionally, the threshold values may be specified as their byte values.

The threshold-support value may also be none, readable, settable, or fixed to make it
a bit more readable. The thresholds are:

0 - lower non critical

1 - lower critical

2 - lower non recoverable

3 - upper non critical

4 - upper critical

5 - upper non recoverable

sensor_set_event_support mc-addr LUN sensor-num events-enable scanning event-support assert-
support deassert-support assert-enabled deassert-enabled

Set the event support of a sensor. The events-enable will enable global events on the
sensor if non-zero, otherwise they are disabled. The scanning values set the scanning
value for the sensor. The event-support value sets the event capabilities in the sen‐
sor, this is the same as the ``sensor event message control support'' value in the
sensor SDR. The assert-support, deassert-support, assert-enabled, and deassert-en‐
abled are all bitmasks (a string of ``0'' and ``1'' characters) that set their corre‐
sponding sensor bit's capability to generate events (support) and whether it will gen‐
erate events now (enabled).

Note that all bitmasks have the rightmost digit as the zeroth bit, and the leftmost
digit as the highest order bit. Note that you must specify 15 bits here, even if you
don't use all of them.

Note that you may use enable or disable in the events-enable field, and you may use
scanning or no-scanning in the scanning field.

For event-support, you may use per-state, entire-sensor, global or none instead of a
number.

For a threshold sensor, the values are:

0
- lower non-critical going low

1
- lower non-critical going high

2
- lower critical going low

3
- lower critical going high

4
- lower non-recoverable going low

5
- lower non-recoverable going high

6
- upper non-critical going low

7
- upper non-critical going high

8
- upper critical going low

9
- upper critical going high

1
- upper non-recoverable going low

1
- upper non-recoverable going high

Note that the "lower going high" and "upper going low" values are not supported, since
they are simply stupid.

ATCA OEM COMMANDS
These are for emulation of special ATCA capabilities.

atca_enable
The system is an ATCA system, enables the other ATCA capabilities.

Note that you should do this *before* creating any MCs (this should really be first)
because the MCs are set up a little differently for ATCA mode. This causes the MCs to
be able to handle PICMG commands properly, sets up 2 LEDs by default, and enables
proper hot-swap handling, including the blue LED. By default the blue LED supports
local control and the other LEDs do not and are red.

In ATCA mode, to drive the hot-swap state machine, you should use sen‐
sor_set_bit_clr_rest to set the hot-swap state.

atca_set_site hardware-address site-type site-number
Sets the given values for an ATCA system, the values returned by the get address com‐
mands.

mc_set_num_leds mc-addr count
Set the number of ATCA LEDs the MC has.

mc_set_power mc-addr power gen-event
Set the ATCA power setting for the MC as its numeric value. If gen-event is non-zero,
generate an event for the change.
