NAME
ipmiutil_sensor - show Sensor Data Records
SYNOPSIS
ipmiutil sensor [-abcdefgjkmpqrstuvwxL -i id -n snum -h tval -l tval -NUPREFJTVY]
DESCRIPTION
ipmiutil sensor is a program that uses IPMI commands to show and decode Sensor Data
Records and current sensor readings for all sensors in the system. This utility can use
either the /dev/ipmi0 driver from OpenIPMI, the /dev/imb driver from Intel, the
/dev/ipmikcs driver from valinux, direct user-space IOs, or the IPMI LAN interface if -N.
Note that this utility by default only displays Sensor Data Records reported by from the
Baseboard Management Controller. To show sensors for other controllers, see options -b
and -m below.
OPTIONS
Command line options are described below.
-a snum
ReArms the sensor number for events
-b Shows SDRs for Bladed (PICMG or ATCA) systems by traversing the child MCs (same as
-e).
-c Show sensor list in a simpler/Canonical format without uninterpreted binary values.
Only the user-friendly interpreted sensor information is shown. (same as -s).
-d <file>
Dump the SDRs to a specified binary file. This file can be used with -j to
jumpstart getting the sensor readings.
-e Show Every SDR in a bladed system by traversing the child MCs (same as -b).
-f <file>
Restore the SDRs from the specified binary File. This is normally only done with
the initial factory provisioning.
-g sens_type
Shows only those SDRs matching the given sensor type group. The sens_type string
can be "fan", "temp", "voltage", or any string or substring matching those in the
IPMI 2.0 Table 42-3 for Sensor Types. Multiple types can be listed, separated by a
comma (,) but no spaces.
-h tval
Highest threshold value to set for the specified sensor. This tval can be in
decimal, or of the form 0x1a, to match the raw reading value shown by sensor
following the " = ". The value passed is set as the non-critical threshold value,
with the more critical ones set by the utility as incrementally lower. This
simplifies the interface and ensures that the threshold values do not get out of
order. This requires specifying the sensor number via -n.
-i ID Show or set only the sensor Index corresponding to ID, where ID is the hex ID of
the SDR as shown in the sensor output under "_ID_". The ID argument can be one hex
number (e.g. 0x0e or 0e), or a range of hex numbers (e.g. 0e-1a or 1a,2a or
0x0e-0x2a). This is useful to repeatedly view just a few sensor readings for
changes, or to set just one sensor quickly without reading all of the SDRs.
-j file
Jump-start by caching the SDRs from a file. This uses an SDR binary file to read
the SDRs, so that only the sensor readings need to be read from the firmware. This
avoids getting the SDR reservation and reading each SDR, so it makes getting the
sensor readings more efficient. The SDR binary file can be created using the -d
option to dump the SDRs to a file, or -j will try to create the file if not there.
-k K When looping with -L, wait K seconds between loops. Default is 1 second.
-l tval
Lowest threshold value to set for the specified sensor. This tval can be in
decimal, or of the form 0x1a, to match the raw reading value shown by sensor
following the " = ". The value passed is set as the non-critical threshold value,
with the more critical ones set by the utility as incrementally higher. This
simplifies the interface and ensures that the threshold values do not get out of
order. This requires specifying the sensor number via -n.
-m 002000s
Show SDRs for a specific MC (e.g. bus 00, sa 20, lun 00). This could be used for
PICMG or ATCA blade systems. The trailing character, if present, indicates SMI
addressing if 's', or IPMB addressing if 'i' or not present.
-n snum
Number of the sensor to set. This num can be in decimal, or of the form 0x1a, to
match the value shown by sensor following the "snum" tag. This is required if
setting hi/lo thresholds via -h/-l.
-o Output the memory DIMM information from SMBIOS, including size. Not available if
using IPMI LAN via -N. Sample output:
Memory Device (0,0): DIMM_A1 : size=2048MB
Memory Device (0,1): DIMM_A2 : not present
-p Persist the threshold being set (as specified via -l or -h). This writes a "sensor
-i" script line to the file /usr/share/ipmiutil/thresholds.sh, which can then be
executed at each reboot by starting the /etc/init.d/ipmi_port service for the
desired runlevels. For Windows, the filename is thresholds.cmd.
-q Show threshold values in d:d:d format. Thresholds are shown for each sensor in
short format with ':' delimiters, which is useful as an example for setting
thresholds with '-u'.
-r Show Raw SDR bytes also.
-s Show sensor list in a simpler/canonical format without uninterpreted binary values.
Only the user-friendly interpreted sensor information is shown. (same as -c).
-t Show any Thresholds for each sensor also, in text format.
-u Set unique threshold values. The values are specified in a string of threshold
values. It can be in raw hex characters or in float values. All 6 possible
thresholds must be specified, but only the ones that are valid for this sensor will
be applied. These values are validated for ordering. For example:
-u 6:5:4:60:65:69 (float) or
-u 0x0605043c4145 (raw hex)
would mean 0x06=noncrit_lo, 0x05=crit_lo, 0x04=nonrec_lo, 0x3c=noncrit_hi,
0x41=crit_hi, 0x45=nonrec_hi.
-v Show Verbose output, including volatile thresholds, SDR thresholds, max/min,
hysteresis, and BMC_TAM decoding.
-w Wrap the threshold data onto the same line as the sensor. This may be convenient
for scripting.
-x Causes eXtra debug messages to be displayed.
-L n Loop n times every K seconds. Default is one loop and K defaults to 1 second. See
option -k to change K seconds if desired. This is useful along with -i or -g to
read some sensors as they change. Using -j with this option makes run it quicker.
-N nodename
Nodename or IP address of the remote target system. If a nodename is specified,
IPMI LAN interface is used. Otherwise the local system management interface is
used.
-P/-R rmt_pswd
Remote password for the nodename given. The default is a null password.
-U rmt_user
Remote username for the nodename given. The default is a null username.
-E Use the remote password from Environment variable IPMI_PASSWORD.
-F drv_t
Force the driver type to one of the followng: imb, va, open, gnu, landesk, lan,
lan2, lan2i, kcs, smb. Note that lan2i means lan2 with intelplus. The default is
to detect any available driver type and use it.
-J Use the specified LanPlus cipher suite (0 thru 17): 0=none/none/none,
1=sha1/none/none, 2=sha1/sha1/none, 3=sha1/sha1/cbc128, 4=sha1/sha1/xrc4_128,
5=sha1/sha1/xrc4_40, 6=md5/none/none, ... 14=md5/md5/xrc4_40. Default is 3.
-T Use a specified IPMI LAN Authentication Type: 0=None, 1=MD2, 2=MD5, 4=Straight
Password, 5=OEM.
-V Use a specified IPMI LAN privilege level. 1=Callback level, 2=User level,
3=Operator level, 4=Administrator level (default), 5=OEM level.
-Y Yes, do prompt the user for the IPMI LAN remote password. Alternatives for the
password are -E or -P.

Output Columns:
_ID_: This is an SDR ID or index number, in hex. This may vary from chassis to chassis.
SDR_Type_xx: This shows the SDR Type and its hex representation. Some SDR types have a
custom display. The OEM SDRs only show the OEM vendor by IANA number and then usually the
data is listed in hex.
ET: For Full or Comp SDRs, this shows the Event Type. For other SDRs, this shows the size
of the SDR entry in hex (Sz).
Own: This is the hex slave address of the SDR Owner, usually 20 if BMC.
a/m: This indicates whether this sensor is either automatically or manually rearmed,
respectively.
Typ: This is the Sensor Type as defined in Table 42-3 of the IPMI 2.0 spec. (01 =
Temperature, 02 = Voltage, 03 = Current, 04 = Fan, etc.)
S_Num: This is the sensor number in hex. This remains consistent across baseboards of the
same type. The output can be parsed with the "snum" delimiter to extract this value.
Sens_Description: This is the text description of this SDR, which is stored within the SDR
on the BMC.
Hex & Interp Reading: This is the raw hex value returned by GetSensorReading, and its
interpreted meaning.
