IPMI-SEL(8) System Commands IPMI-SEL(8)
NAME
ipmi-sel - display SEL entries
SYNOPSIS
ipmi-sel [OPTION...]
DESCRIPTION
Ipmi-sel is used to view and manage System Event Log (SEL) entries. SEL
records store system event information and may be useful for debugging
problems.
Ipmi-sel does not inform the user if an event is particularly good or
bad, just that the event occurred. Users may wish to use the --out‐
put-event-state option to output the analyzed state.
Listed below are general IPMI options, tool specific options, trouble
shooting information, workaround information, examples, and known
issues. For a general introduction to FreeIPMI please see freeipmi(7).
To perform some advanced SEL management, please see bmc-device(8).
GENERAL OPTIONS
The following options are general options for configuring IPMI communi‐
cation and executing general tool commands.
-D IPMIDRIVER, --driver-type=IPMIDRIVER
Specify the driver type to use instead of doing an auto selec‐
tion. The currently available outofband drivers are LAN and
LAN_2_0, which perform IPMI 1.5 and IPMI 2.0 respectively. The
currently available inband drivers are KCS, SSIF, OPENIPMI, and
SUNBMC.
--disable-auto-probe
Do not probe in-band IPMI devices for default settings.
--driver-address=DRIVER-ADDRESS
Specify the in-band driver address to be used instead of the
probed value. DRIVER-ADDRESS should be prefixed with "0x" for a
hex value and '0' for an octal value.
--driver-device=DEVICE
Specify the in-band driver device path to be used instead of the
probed path.
--register-spacing=REGISTER-SPACING
Specify the in-band driver register spacing instead of the
probed value. Argument is in bytes (i.e. 32bit register spacing
= 4)
--target-channel-number=CHANNEL-NUMBER
Specify the in-band driver target channel number to send IPMI
requests to.
--target-slave-address=SLAVE-ADDRESS
Specify the in-band driver target slave number to send IPMI
requests to.
-h IPMIHOST1,IPMIHOST2,..., --hostname=IPMIHOST1[:PORT],IPMI‐
HOST2[:PORT],...
Specify the remote host(s) to communicate with. Multiple host‐
names may be separated by comma or may be specified in a range
format; see HOSTRANGED SUPPORT below. An optional port can be
specified with each host, which may be useful in port forwarding
or similar situations.
-u USERNAME, --username=USERNAME
Specify the username to use when authenticating with the remote
host. If not specified, a null (i.e. anonymous) username is
assumed. The user must have atleast USER privileges in order for
this tool to operate fully.
-p PASSWORD, --password=PASSWORD
Specify the password to use when authenticationg with the remote
host. If not specified, a null password is assumed. Maximum
password length is 16 for IPMI 1.5 and 20 for IPMI 2.0.
-P, --password-prompt
Prompt for password to avoid possibility of listing it in
process lists.
-k K_G, --k-g=K_G
Specify the K_g BMC key to use when authenticating with the
remote host for IPMI 2.0. If not specified, a null key is
assumed. To input the key in hexadecimal form, prefix the string
with '0x'. E.g., the key 'abc' can be entered with the either
the string 'abc' or the string '0x616263'
-K, --k-g-prompt
Prompt for k-g to avoid possibility of listing it in process
lists.
--session-timeout=MILLISECONDS
Specify the session timeout in milliseconds. Defaults to 20000
milliseconds (20 seconds) if not specified.
--retransmission-timeout=MILLISECONDS
Specify the packet retransmission timeout in milliseconds.
Defaults to 1000 milliseconds (1 second) if not specified. The
retransmission timeout cannot be larger than the session time‐
out.
-a AUTHENTICATION-TYPE, --authentication-type=AUTHENTICATION-TYPE
Specify the IPMI 1.5 authentication type to use. The currently
available authentication types are NONE, STRAIGHT_PASSWORD_KEY,
MD2, and MD5. Defaults to MD5 if not specified.
-I CIPHER-SUITE-ID, --cipher-suite-id=CIPHER-SUITE-ID
Specify the IPMI 2.0 cipher suite ID to use. The Cipher Suite ID
identifies a set of authentication, integrity, and confidential‐
ity algorithms to use for IPMI 2.0 communication. The authenti‐
cation algorithm identifies the algorithm to use for session
setup, the integrity algorithm identifies the algorithm to use
for session packet signatures, and the confidentiality algorithm
identifies the algorithm to use for payload encryption. Defaults
to cipher suite ID 3 if not specified. The following cipher
suite ids are currently supported:
0 - Authentication Algorithm = None; Integrity Algorithm = None;
Confidentiality Algorithm = None
1 - Authentication Algorithm = HMAC-SHA1; Integrity Algorithm =
None; Confidentiality Algorithm = None
2 - Authentication Algorithm = HMAC-SHA1; Integrity Algorithm =
HMAC-SHA1-96; Confidentiality Algorithm = None
3 - Authentication Algorithm = HMAC-SHA1; Integrity Algorithm =
HMAC-SHA1-96; Confidentiality Algorithm = AES-CBC-128
6 - Authentication Algorithm = HMAC-MD5; Integrity Algorithm =
None; Confidentiality Algorithm = None
7 - Authentication Algorithm = HMAC-MD5; Integrity Algorithm =
HMAC-MD5-128; Confidentiality Algorithm = None
8 - Authentication Algorithm = HMAC-MD5; Integrity Algorithm =
HMAC-MD5-128; Confidentiality Algorithm = AES-CBC-128
11 - Authentication Algorithm = HMAC-MD5; Integrity Algorithm =
MD5-128; Confidentiality Algorithm = None
12 - Authentication Algorithm = HMAC-MD5; Integrity Algorithm =
MD5-128; Confidentiality Algorithm = AES-CBC-128
15 - Authentication Algorithm = HMAC-SHA256; Integrity Algorithm
= None; Confidentiality Algorithm = None
16 - Authentication Algorithm = HMAC-SHA256; Integrity Algorithm
= HMAC_SHA256_128; Confidentiality Algorithm = None
17 - Authentication Algorithm = HMAC-SHA256; Integrity Algorithm
= HMAC_SHA256_128; Confidentiality Algorithm = AES-CBC-128
-l PRIVILEGE-LEVEL, --privilege-level=PRIVILEGE-LEVEL
Specify the privilege level to be used. The currently available
privilege levels are USER, OPERATOR, and ADMIN. Defaults to
OPERATOR if not specified.
--config-file=FILE
Specify an alternate configuration file.
-W WORKAROUNDS, --workaround-flags=WORKAROUNDS
Specify workarounds to vendor compliance issues. Multiple work‐
arounds can be specified separated by commas. A special command
line flag of "none", will indicate no workarounds (may be useful
for overriding configured defaults). See WORKAROUNDS below for a
list of available workarounds.
--debug
Turn on debugging.
-?, --help
Output a help list and exit.
--usage
Output a usage message and exit.
-V, --version
Output the program version and exit.
IPMI-SEL OPTIONS
The following options are specific to Ipmi-sel.
-v Output verbose output. This option will output event direction.
Event direction may be useful to differentiate severity between
some events. For example, some motherboards may issue an event
both when a temperature exceeds a threshold and when it goes
back down below it.
-vv Output very verbose output. This option will output additional
information than verbose output. Most notably it will output
additional hex codes to given information on ambiguous SEL
entries. For example, it will output Generator ID hex codes for
sensors without names.
-i, --info
Show general information about the SEL.
--display=RECORD-IDS-LIST
Display SEL records by record id. Accepts space or comma sepa‐
rated lists.
--exclude-display=RECORD-IDS-LIST
Exclude display of SEL records by record id. Accepts space or
comma separated lists.
--display-range=START-END
Display SEL records from record id START to END.
--exclude-display-range=START-END
Exclude display of SEL records from record id START to END.
--date-range=DATE-DATE
Display SEL records with events occurring in the specified date
range. Dates may be specified in MM/DD/YYYY or MM-DD-YYYY for‐
mat. The month may be specified as a numeral or its abbreviated
string name. The current local system time can be specified with
"now". Note that non-timestamped records will not be displayed
automatically because they do not possess a timestamp.
--exclude-date-range=DATE-DATE
Exclude display of SEL records with events occurring in the
specified date range. Dates may be specified in MM/DD/YYYY or
MM-DD-YYYY format. The month may be specified as a numeral or
its abbreviated string name. The current local system time can
be specified with "now". Note that non-timestamped records will
be displayed automatically because they do not possess a time‐
stamp.
-t SENSOR-TYPE-LIST, --sensor-types=SENSOR-TYPE-LIST
Specify sensor types to show SEL events for. Multiple types can
be separated by commas or spaces. A special command line type of
"all", will indicate all types should be shown (may be useful
for overriding configured defaults). Users may specify sensor
types by string (see --list-sensor-types below) or by number
(decimal or hex).
-T SENSOR-TYPE-LIST, --exclude-sensor-types=SENSOR-TYPE-LIST
Specify sensor types to not show SEL events for. Multiple types
can be separated by commas or spaces. A special command line
type of "none", will indicate no types should be excluded (may
be useful for overriding configured defaults). Users may specify
sensor types by string (see --list-sensor-types below) or by
number (decimal or hex).
-L, --list-sensor-types
List sensor types.
--tail=count
Display approximately the last count SEL records. The display
count is calculated by approximating the record ids of the last
SEL records. It's correctness depends highly on the SEL imple‐
mentation by the vendor.
--clear
Clear SEL.
--post-clear
Identical to --clear, except the SEL clearning will be performed
after SEL event records are displayed. This option is useful for
scripting if users intend to log SEL events to another log, then
immediately clear SEL. Unlike calling --clear in another execu‐
tion of ipmi-sel, this option will use SEL reservations to
notify the user if a SEL change has occurred while displaying
and clearing the SEL. This can protect users from a race, where
a new SEL event is unknowingly generated before clearing the
SEL. Note that SEL reservations are optionally implemented by
vendors and may not be available on all machines.
--delete=RECORD-IDS-LIST
Delete records by record id in the SEL. Accepts space or comma
separated lists.
--delete-range=START-END
Delete record ids from START to END in the SEL.
--system-event-only
Output only system event records (i.e. don't output OEM
records).
--oem-event-only
Output only OEM event records (i.e. don't output system event
records).
--output-manufacturer-id
For OEM SEL record types, output the manufacturer ID along with
event data when available.
--output-event-state
Output event state in output. This will add an additional output
reporting if an event should be viewed as NOMINAL, WARNING, or
CRITICAL. The event state is an interpreted value based on the
configuration file /etc//freeipmi_interpret_sel.conf and the
event direction. See freeipmi_interpret_sel.conf(5) for more
information.
--event-state-config-file=FILE
Specify an alternate event state configuration file. Option
ignored if --output-event-state not specified.
--hex-dump
Hex-dump SEL entries.
--interpret-oem-data
Attempt to interpret OEM data, such as event data, sensor read‐
ings, or general extra info, etc. If an OEM interpretation is
not available, the default output will be generated. Correctness
of OEM interpretations cannot be guaranteed due to potential
changes OEM vendors may make in products, firmware, etc. See OEM
INTERPRETATION below for confirmed supported motherboard inter‐
pretations.
--output-oem-event-strings
Some motherboards support an IPMI OEM extension that returns the
string output for a system event. Such string output may be ben‐
eficial for determining the meaning behind OEM specific events.
This option will use the OEM event string to describe all system
events in the ipmi-sel output. This option differs from --inter‐
pret-oem-data option in that all system events will output the
vendor supplied event string, not just events that are OEM spe‐
cific. The event string may be very different from the normal
FreeIPMI event string output. If an OEM event strings is not
available, the default output will be output. This option is
confirmed to work for Fujitsu iRMC S1 and iRMC S2 systems.
--entity-sensor-names
Output sensor names prefixed with their entity id and instance
number when appropriate. This may be necessary on some mother‐
boards to help identify what sensors are referencing. For exam‐
ple, a motherboard may have multiple sensors named 'TEMP'. The
entity id and instance number may help clarify which sensor
refers to "Processor 1" vs. "Processor 2".
--no-sensor-type-output
Do not show sensor type output for each entry. On many systems,
the sensor type is redundant to the name of the sensor. This can
especially be true if --entity-sensor-names is specified. If
the sensor name is sufficient, or if the sensor type is of no
interest to the user, this option can be specified to condense
output.
--comma-separated-output
Output fields in comma separated format.
--no-header-output
Do not output column headers. May be useful in scripting.
--non-abbreviated-units
Output non-abbreviated units (e.g. 'Amps' instead of 'A'). May
aid in disambiguation of units (e.g. 'C' for Celsius or
Coulombs).
--legacy-output
Output in legacy format. Newer options may not be applicable to
legacy output.
SDR CACHE OPTIONS
This tool requires access to the sensor data repository (SDR) cache for
general operation. By default, SDR data will be downloaded and cached
on the local machine. The following options apply to the SDR cache.
-f, --flush-cache
Flush a cached version of the sensor data repository (SDR)
cache. The SDR is typically cached for faster subsequent access.
However, it may need to be flushed and re-generated if the SDR
has been updated on a system.
-Q, --quiet-cache
Do not output information about cache creation/deletion. May be
useful in scripting.
--sdr-cache-recreate
If the SDR cache is out of date or invalid, automatically recre‐
ate the sensor data repository (SDR) cache. This option may be
useful for scripting purposes.
--sdr-cache-file=FILE
Specify a specific sensor data repository (SDR) cache file to be
stored or read from. If this option is used when multiple hosts
are specified, the same SDR cache file will be used for all
hosts.
--sdr-cache-directory=DIRECTORY
Specify an alternate directory for sensor data repository (SDR)
caches to be stored or read from. Defaults to the home directory
if not specified.
--ignore-sdr-cache
Ignore SDR cache related processing. May lead to incomplete or
less useful information being output, however it will allow
functionality for systems without SDRs or when the correct SDR
cannot be loaded.
HOSTRANGED OPTIONS
The following options manipulate hostranged output. See HOSTRANGED SUP‐
PORT below for additional information on hostranges.
-B, --buffer-output
Buffer hostranged output. For each node, buffer standard output
until the node has completed its IPMI operation. When specifying
this option, data may appear to output slower to the user since
the the entire IPMI operation must complete before any data can
be output. See HOSTRANGED SUPPORT below for additional informa‐
tion.
-C, --consolidate-output
Consolidate hostranged output. The complete standard output from
every node specified will be consolidated so that nodes with
identical output are not output twice. A header will list those
nodes with the consolidated output. When this option is speci‐
fied, no output can be seen until the IPMI operations to all
nodes has completed. If the user breaks out of the program
early, all currently consolidated output will be dumped. See
HOSTRANGED SUPPORT below for additional information.
-F NUM, --fanout=NUM
Specify multiple host fanout. A "sliding window" (or fanout)
algorithm is used for parallel IPMI communication so that slower
nodes or timed out nodes will not impede parallel communication.
The maximum number of threads available at the same time is lim‐
ited by the fanout. The default is 64.
-E, --eliminate
Eliminate hosts determined as undetected by ipmidetect. This
attempts to remove the common issue of hostranged execution tim‐
ing out due to several nodes being removed from service in a
large cluster. The ipmidetectd daemon must be running on the
node executing the command.
--always-prefix
Always prefix output, even if only one host is specified or com‐
municating in-band. This option is primarily useful for script‐
ing purposes. Option will be ignored if specified with the -C
option.
HOSTRANGED SUPPORT
Multiple hosts can be input either as an explicit comma separated lists
of hosts or a range of hostnames in the general form: prefix[n-m,l-
k,...], where n < m and l < k, etc. The later form should not be con‐
fused with regular expression character classes (also denoted by []).
For example, foo[19] does not represent foo1 or foo9, but rather repre‐
sents a degenerate range: foo19.
This range syntax is meant only as a convenience on clusters with a
prefixNN naming convention and specification of ranges should not be
considered necessary -- the list foo1,foo9 could be specified as such,
or by the range foo[1,9].
Some examples of range usage follow:
foo[01-05] instead of foo01,foo02,foo03,foo04,foo05
foo[7,9-10] instead of foo7,foo9,foo10
foo[0-3] instead of foo0,foo1,foo2,foo3
As a reminder to the reader, some shells will interpret brackets ([ and
]) for pattern matching. Depending on your shell, it may be necessary
to enclose ranged lists within quotes.
When multiple hosts are specified by the user, a thread will be exe‐
cuted for each host in parallel up to the configured fanout (which can
be adjusted via the -F option). This will allow communication to large
numbers of nodes far more quickly than if done in serial.
By default, standard output from each node specified will be output
with the hostname prepended to each line. Although this output is read‐
able in many situations, it may be difficult to read in other situa‐
tions. For example, output from multiple nodes may be mixed together.
The -B and -C options can be used to change this default.
In-band IPMI Communication will be used when the host "localhost" is
specified. This allows the user to add the localhost into the hos‐
tranged output.
GENERAL TROUBLESHOOTING
Most often, IPMI problems are due to configuration problems.
IPMI over LAN problems involve a misconfiguration of the remote
machine's BMC. Double check to make sure the following are configured
properly in the remote machine's BMC: IP address, MAC address, subnet
mask, username, user enablement, user privilege, password, LAN privi‐
lege, LAN enablement, and allowed authentication type(s). For IPMI 2.0
connections, double check to make sure the cipher suite privilege(s)
and K_g key are configured properly. The bmc-config(8) tool can be used
to check and/or change these configuration settings.
Inband IPMI problems are typically caused by improperly configured
drivers or non-standard BMCs.
In addition to the troubleshooting tips below, please see WORKAROUNDS
below to also if there are any vendor specific bugs that have been dis‐
covered and worked around.
Listed below are many of the common issues for error messages. For
additional support, please e-mail the <freeipmi-users@gnu.org> mailing
list.
"username invalid" - The username entered (or a NULL username if none
was entered) is not available on the remote machine. It may also be
possible the remote BMC's username configuration is incorrect.
"password invalid" - The password entered (or a NULL password if none
was entered) is not correct. It may also be possible the password for
the user is not correctly configured on the remote BMC.
"password verification timeout" - Password verification has timed out.
A "password invalid" error (described above) or a generic "session
timeout" (described below) occurred. During this point in the protocol
it cannot be differentiated which occurred.
"k_g invalid" - The K_g key entered (or a NULL K_g key if none was
entered) is not correct. It may also be possible the K_g key is not
correctly configured on the remote BMC.
"privilege level insufficient" - An IPMI command requires a higher user
privilege than the one authenticated with. Please try to authenticate
with a higher privilege. This may require authenticating to a different
user which has a higher maximum privilege.
"privilege level cannot be obtained for this user" - The privilege
level you are attempting to authenticate with is higher than the maxi‐
mum allowed for this user. Please try again with a lower privilege. It
may also be possible the maximum privilege level allowed for a user is
not configured properly on the remote BMC.
"authentication type unavailable for attempted privilege level" - The
authentication type you wish to authenticate with is not available for
this privilege level. Please try again with an alternate authentication
type or alternate privilege level. It may also be possible the avail‐
able authentication types you can authenticate with are not correctly
configured on the remote BMC.
"cipher suite id unavailable" - The cipher suite id you wish to authen‐
ticate with is not available on the remote BMC. Please try again with
an alternate cipher suite id. It may also be possible the available
cipher suite ids are not correctly configured on the remote BMC.
"ipmi 2.0 unavailable" - IPMI 2.0 was not discovered on the remote
machine. Please try to use IPMI 1.5 instead.
"connection timeout" - Initial IPMI communication failed. A number of
potential errors are possible, including an invalid hostname specified,
an IPMI IP address cannot be resolved, IPMI is not enabled on the
remote server, the network connection is bad, etc. Please verify con‐
figuration and connectivity.
"session timeout" - The IPMI session has timed out. Please reconnect.
If this error occurs often, you may wish to increase the retransmission
timeout. Some remote BMCs are considerably slower than others.
"device not found" - The specified device could not be found. Please
check configuration or inputs and try again.
"driver timeout" - Communication with the driver or device has timed
out. Please try again.
"message timeout" - Communication with the driver or device has timed
out. Please try again.
"BMC busy" - The BMC is currently busy. It may be processing informa‐
tion or have too many simultaneous sessions to manage. Please wait and
try again.
"could not find inband device" - An inband device could not be found.
Please check configuration or specify specific device or driver on the
command line.
"driver timeout" - The inband driver has timed out communicating to the
local BMC or service processor. The BMC or service processor may be
busy or (worst case) possibly non-functioning.
IPMI-SEL TROUBLESHOOTING
Some timestamps in the SEL may report a date of 1-Jan-1970, the epoch
for SEL timestamps. This timestamp is not necessarily incorrect. It
usually indicates a hardware event that occurred before a timestamp in
firmware has been initialized. For example, certain hardware components
will have their internal clocks reset during a power cycle.
However, if the internal clock of the SEL appears to be regularly
incorrect, you may need to set the SEL time. This can be done using
bmc-device(8).
The following are common SEL related messages.
"sel config file parse error" - A parse error was found in the sel
event interpretation configuration file. Please see freeipmi_inter‐
pret_sel.conf(5).
WORKAROUNDS
With so many different vendors implementing their own IPMI solutions,
different vendors may implement their IPMI protocols incorrectly. The
following describes a number of workarounds currently available to han‐
dle discovered compliance issues. When possible, workarounds have been
implemented so they will be transparent to the user. However, some will
require the user to specify a workaround be used via the -W option.
The hardware listed below may only indicate the hardware that a problem
was discovered on. Newer versions of hardware may fix the problems
indicated below. Similar machines from vendors may or may not exhibit
the same problems. Different vendors may license their firmware from
the same IPMI firmware developer, so it may be worthwhile to try work‐
arounds listed below even if your motherboard is not listed.
If you believe your hardware has an additional compliance issue that
needs a workaround to be implemented, please contact the FreeIPMI main‐
tainers on <freeipmi-users@gnu.org> or <freeipmi-devel@gnu.org>.
assumeio - This workaround flag will assume inband interfaces communi‐
cate with system I/O rather than being memory-mapped. This will work
around systems that report invalid base addresses. Those hitting this
issue may see "device not supported" or "could not find inband device"
errors. Issue observed on HP ProLiant DL145 G1.
spinpoll - This workaround flag will inform some inband drivers (most
notably the KCS driver) to spin while polling rather than putting the
process to sleep. This may significantly improve the wall clock running
time of tools because an operating system scheduler's granularity may
be much larger than the time it takes to perform a single IPMI message
transaction. However, by spinning, your system may be performing less
useful work by not contexting out the tool for a more useful task.
authcap - This workaround flag will skip early checks for username
capabilities, authentication capabilities, and K_g support and allow
IPMI authentication to succeed. It works around multiple issues in
which the remote system does not properly report username capabilities,
authentication capabilities, or K_g status. Those hitting this issue
may see "username invalid", "authentication type unavailable for
attempted privilege level", or "k_g invalid" errors. Issue observed on
Asus P5M2/P5MT-R/RS162-E4/RX4, Intel SR1520ML/X38ML, and Sun Fire
2200/4150/4450 with ELOM.
idzero - This workaround flag will allow empty session IDs to be
accepted by the client. It works around IPMI sessions that report empty
session IDs to the client. Those hitting this issue may see "session
timeout" errors. Issue observed on Tyan S2882 with M3289 BMC.
unexpectedauth - This workaround flag will allow unexpected non-null
authcodes to be checked as though they were expected. It works around
an issue when packets contain non-null authentication data when they
should be null due to disabled per-message authentication. Those hit‐
ting this issue may see "session timeout" errors. Issue observed on
Dell PowerEdge 2850,SC1425. Confirmed fixed on newer firmware.
forcepermsg - This workaround flag will force per-message authentica‐
tion to be used no matter what is advertised by the remote system. It
works around an issue when per-message authentication is advertised as
disabled on the remote system, but it is actually required for the pro‐
tocol. Those hitting this issue may see "session timeout" errors.
Issue observed on IBM eServer 325.
endianseq - This workaround flag will flip the endian of the session
sequence numbers to allow the session to continue properly. It works
around IPMI 1.5 session sequence numbers that are the wrong endian.
Those hitting this issue may see "session timeout" errors. Issue
observed on some Sun ILOM 1.0/2.0 (depends on service processor
endian).
noauthcodecheck - This workaround flag will tell FreeIPMI to not check
the authentication codes returned from IPMI 1.5 command responses. It
works around systems to return invalid authentication codes due to
hashing or implementation errors. Users are cautioned on the use of
this option, as it removes an authentication check verifying the valid‐
ity of a packet. However, in most organizations, this is unlikely to be
a security issue. Those hitting this issue may see "connection time‐
out", "session timeout", or "password verification timeout" errors.
Issue observed on Xyratex FB-H8-SRAY.
intel20 - This workaround flag will work around several Intel IPMI 2.0
authentication issues. The issues covered include padding of usernames,
and password truncation if the authentication algorithm is HMAC-
MD5-128. Those hitting this issue may see "username invalid", "password
invalid", or "k_g invalid" errors. Issue observed on Intel SE7520AF2
with Intel Server Management Module (Professional Edition).
supermicro20 - This workaround flag will work around several Supermicro
IPMI 2.0 authentication issues on motherboards w/ Peppercon IPMI
firmware. The issues covered include handling invalid length authenti‐
cation codes. Those hitting this issue may see "password invalid"
errors. Issue observed on Supermicro H8QME with SIMSO daughter card.
Confirmed fixed on newerver firmware.
sun20 - This workaround flag will work work around several Sun IPMI 2.0
authentication issues. The issues covered include invalid lengthed hash
keys, improperly hashed keys, and invalid cipher suite records. Those
hitting this issue may see "password invalid" or "bmc error" errors.
Issue observed on Sun Fire 4100/4200/4500 with ILOM. This workaround
automatically includes the "opensesspriv" workaround.
opensesspriv - This workaround flag will slightly alter FreeIPMI's IPMI
2.0 connection protocol to workaround an invalid hashing algorithm used
by the remote system. The privilege level sent during the Open Session
stage of an IPMI 2.0 connection is used for hashing keys instead of the
privilege level sent during the RAKP1 connection stage. Those hitting
this issue may see "password invalid", "k_g invalid", or "bad rmcpplus
status code" errors. Issue observed on Sun Fire 4100/4200/4500 with
ILOM, Inventec 5441/Dell Xanadu II, Supermicro X8DTH, Supermicro X8DTG,
Intel S5500WBV/Penguin Relion 700, Intel S2600JF/Appro 512X, and Quanta
QSSC-S4R//Appro GB812X-CN. This workaround is automatically triggered
with the "sun20" workaround.
integritycheckvalue - This workaround flag will work around an invalid
integrity check value during an IPMI 2.0 session establishment when
using Cipher Suite ID 0. The integrity check value should be 0 length,
however the remote motherboard responds with a non-empty field. Those
hitting this issue may see "k_g invalid" errors. Issue observed on
Supermicro X8DTG, Supermicro X8DTU, and Intel S5500WBV/Penguin Relion
700, and Intel S2600JF/Appro 512X.
assumemaxsdrrecordcount - This workaround will inform SDR reading to
stop reading after a known maximum numer of SDR records have been read.
This will work around systems that have mis-implemented SDR reading
functions that. Those hitting this issue may see "SDR record count
invalid" errors. Issue observed on unspecified Inspur motherboard.
assumesystemevent - This workaround option will assume invalid SEL
record types are system event records. Records may be formatted cor‐
rectly but report invalid record types. Those hitting this issue may
see "Unknown SEL Record Type" errors. Output may be unknown, pray for
the best. This option is confirmed to work around compliances issues on
HP DL 380 G5 motherboards.
No IPMI 1.5 Support - Some motherboards that support IPMI 2.0 have been
found to not support IPMI 1.5. Those hitting this issue may see "ipmi
2.0 unavailable" or "connection timeout" errors. This issue can be
worked around by using IPMI 2.0 instead of IPMI 1.5 by specifying
--driver-address=LAN_2_0. Issue observed on HP Proliant DL 145.
OEM INTERPRETATION
The following motherboards are confirmed to have atleast some support
by the --interpret-oem-data option. While highly probable the OEM data
interpretations would work across other motherboards by the same manu‐
facturer, there are no guarantees. Some of the motherboards below may
be rebranded by vendors/distributors.

EXAMPLES
# ipmi-sel
Show all SEL records on the local machine.
# ipmi-sel -h ahost -u myusername -p mypassword
Show all SEL records of a remote machine using IPMI over LAN.
# ipmi-sel -h mycluster[0-127] -u myusername -p mypassword
Show all SEL records across a cluster using IPMI over LAN.
# ipmi-sel --delete=44,82
Delete SEL records 44 and 82 on the local machine.
# ipmi-sel --delete-all
Delete all SEL entries on the local machine.
# ipmi-sel --delete-range=12-42
Delete SEL entries in the range 12 to 42 on the local machine.
DIAGNOSTICS
Upon successful execution, exit status is 0. On error, exit status is
1.
If multiple hosts are specified for communication, the exit status is 0
if and only if all targets successfully execute. Otherwise the exit
status is 1.
KNOWN ISSUES
On older operating systems, if you input your username, password, and
other potentially security relevant information on the command line,
this information may be discovered by other users when using tools like
the ps(1) command or looking in the /proc file system. It is generally
more secure to input password information with options like the -P or
-K options. Configuring security relevant information in the FreeIPMI
configuration file would also be an appropriate way to hide this infor‐
mation.
In order to prevent brute force attacks, some BMCs will temporarily
"lock up" after a number of remote authentication errors. You may need
to wait awhile in order to this temporary "lock up" to pass before you
may authenticate again.
