SYNOPSIS

9       ipmi-fru [OPTION...]
10

DESCRIPTION

12       Ipmi-fru displays Field Replaceable Unit (FRU) Information. The FRU may
13       hold a variety of information, such  as  device  information,  hardware
14       information, serial numbers, and part numbers.
15
16       Listed  below  are general IPMI options, tool specific options, trouble
17       shooting  information,  workaround  information,  examples,  and  known
18       issues. For a general introduction to FreeIPMI please see freeipmi(7).

GENERAL OPTIONS

21       The following options are general options for configuring IPMI communi‐
22       cation and executing general tool commands.
23
24       -D IPMIDRIVER, --driver-type=IPMIDRIVER
25              Specify the driver type to use instead of doing an  auto  selec‐
26              tion.   The  currently  available  outofband drivers are LAN and
27              LAN_2_0, which perform IPMI 1.5 and IPMI 2.0  respectively.  The
28              currently  available  inband  drivers  are  KCS, SSIF, OPENIPMI,
29              SUNBMC, and INTELDCMI.
30
31       --disable-auto-probe
32              Do not probe in-band IPMI devices for default settings.
33
34       --driver-address=DRIVER-ADDRESS
35              Specify the in-band driver address to be  used  instead  of  the
36              probed  value. DRIVER-ADDRESS should be prefixed with "0x" for a
37              hex value and '0' for an octal value.
38
39       --driver-device=DEVICE
40              Specify the in-band driver device path to be used instead of the
41              probed path.
42
43       --register-spacing=REGISTER-SPACING
44              Specify  the  in-band  driver  register  spacing  instead of the
45              probed value. Argument is in bytes (i.e. 32bit register  spacing
46              = 4)
47
48       --target-channel-number=CHANNEL-NUMBER
49              Specify  the  in-band  driver target channel number to send IPMI
50              requests to.
51
52       --target-slave-address=SLAVE-ADDRESS
53              Specify the in-band driver target  slave  number  to  send  IPMI
54              requests to.
55
56       -h      IPMIHOST1,IPMIHOST2,...,      --hostname=IPMIHOST1[:PORT],IPMI‐
57       HOST2[:PORT],...
58              Specify the remote host(s) to communicate with.  Multiple  host‐
59              names  may  be separated by comma or may be specified in a range
60              format; see HOSTRANGED SUPPORT below. An optional  port  can  be
61              specified with each host, which may be useful in port forwarding
62              or similar situations.  If specifying an IPv6 address and  port,
63              use the format [ADDRESS]:PORT.
64
65       -u USERNAME, --username=USERNAME
66              Specify  the username to use when authenticating with the remote
67              host.  If not specified, a null  (i.e.  anonymous)  username  is
68              assumed. The user must have atleast USER privileges in order for
69              this tool to operate fully.
70
71       -p PASSWORD, --password=PASSWORD
72              Specify the password to use when authenticationg with the remote
73              host.   If  not  specified,  a null password is assumed. Maximum
74              password length is 16 for IPMI 1.5 and 20 for IPMI 2.0.
75
76       -P, --password-prompt
77              Prompt for password  to  avoid  possibility  of  listing  it  in
78              process lists.
79
80       -k K_G, --k-g=K_G
81              Specify  the  K_g  BMC  key  to use when authenticating with the
82              remote host for IPMI 2.0.  If  not  specified,  a  null  key  is
83              assumed. To input the key in hexadecimal form, prefix the string
84              with '0x'. E.g., the key 'abc' can be entered  with  the  either
85              the string 'abc' or the string '0x616263'
86
87       -K, --k-g-prompt
88              Prompt  for  k-g  to  avoid possibility of listing it in process
89              lists.
90
91       --session-timeout=MILLISECONDS
92              Specify the session timeout in milliseconds. Defaults  to  20000
93              milliseconds (20 seconds) if not specified.
94
95       --retransmission-timeout=MILLISECONDS
96              Specify  the  packet  retransmission  timeout  in  milliseconds.
97              Defaults to 1000 milliseconds (1 second) if not  specified.  The
98              retransmission  timeout  cannot be larger than the session time‐
99              out.
100
101       -a AUTHENTICATION-TYPE, --authentication-type=AUTHENTICATION-TYPE
102              Specify the IPMI 1.5 authentication type to use.  The  currently
103              available  authentication types are NONE, STRAIGHT_PASSWORD_KEY,
104              MD2, and MD5. Defaults to MD5 if not specified.
105
106       -I CIPHER-SUITE-ID, --cipher-suite-id=CIPHER-SUITE-ID
107              Specify the IPMI 2.0 cipher suite ID to use. The Cipher Suite ID
108              identifies a set of authentication, integrity, and confidential‐
109              ity algorithms to use for IPMI 2.0 communication. The  authenti‐
110              cation  algorithm  identifies  the  algorithm to use for session
111              setup, the integrity algorithm identifies the algorithm  to  use
112              for session packet signatures, and the confidentiality algorithm
113              identifies the algorithm to use for payload encryption. Defaults
114              to  cipher  suite  ID  3  if not specified. The following cipher
115              suite ids are currently supported:

145              = None; Confidentiality Algorithm = None
146
147              16 - Authentication Algorithm = HMAC-SHA256; Integrity Algorithm
148              = HMAC_SHA256_128; Confidentiality Algorithm = None
149
150              17 - Authentication Algorithm = HMAC-SHA256; Integrity Algorithm
151              = HMAC_SHA256_128; Confidentiality Algorithm = AES-CBC-128
152
153       -l PRIVILEGE-LEVEL, --privilege-level=PRIVILEGE-LEVEL
154              Specify the privilege level to be used. The currently  available
155              privilege levels are USER, OPERATOR, and ADMIN. Defaults to USER
156              if not specified.
157
158       --config-file=FILE
159              Specify an alternate configuration file.
160
161       -W WORKAROUNDS, --workaround-flags=WORKAROUNDS
162              Specify workarounds to vendor compliance issues. Multiple  work‐
163              arounds  can be specified separated by commas. A special command
164              line flag of "none", will indicate no workarounds (may be useful
165              for overriding configured defaults). See WORKAROUNDS below for a
166              list of available workarounds.
167
168       --debug
169              Turn on debugging.
170
171       -?, --help
172              Output a help list and exit.
173
174       --usage
175              Output a usage message and exit.
176
177       -V, --version
178              Output the program version and exit.
179

IPMI-FRU OPTIONS

181       The following options are specific to ipmi-fru.
182
183       -e, --device-id=IDNUM
184              Specify a specific FRU device ID.
185
186       -v, --verbose
187              Increase verbosity in output to include additional output.
188
189       --bridge-fru
190              By default, FRU entries on other satellite controllers will  not
191              be  read  by  default.  Bridging  may  not  work  on some inter‐
192              faces/driver types.
193
194       --interpret-oem-data
195              Attempt to interpret OEM data, such as event data, sensor  read‐
196              ings,  or  general  extra info, etc. If an OEM interpretation is
197              not available, the default output will be generated. Correctness
198              of  OEM  interpretations  cannot  be guaranteed due to potential
199              changes OEM vendors may make in products, firmware, etc. See OEM
200              INTERPRETATION  below for confirmed supported motherboard inter‐
201              pretations.
202
203       --fru-file=FILENAME
204              Output data from the specified FRU binary file instead of  read‐
205              ing FRU data off of a board.
206

SDR CACHE OPTIONS

208       This tool requires access to the sensor data repository (SDR) cache for
209       general operation. By default, SDR data will be downloaded  and  cached
210       on the local machine. The following options apply to the SDR cache.
211
212       --flush-cache
213              Flush  a  cached  version  of  the  sensor data repository (SDR)
214              cache. The SDR is typically cached for faster subsequent access.
215              However,  it  may need to be flushed and re-generated if the SDR
216              has been updated on a system.
217
218       --quiet-cache
219              Do not output information about cache creation/deletion. May  be
220              useful in scripting.
221
222       --sdr-cache-recreate
223              If the SDR cache is out of date or invalid, automatically recre‐
224              ate the sensor data repository (SDR) cache. This option  may  be
225              useful for scripting purposes.
226
227       --sdr-cache-file=FILE
228              Specify a specific sensor data repository (SDR) cache file to be
229              stored or read from. If this option is used when multiple  hosts
230              are  specified,  the  same  SDR  cache file will be used for all
231              hosts.
232
233       --sdr-cache-directory=DIRECTORY
234              Specify an alternate directory for sensor data repository  (SDR)
235              caches to be stored or read from. Defaults to the home directory
236              if not specified.
237
238       --ignore-sdr-cache
239              Ignore SDR cache related processing. May lead to  incomplete  or
240              less  useful  information  being  output,  however it will allow
241              functionality for systems without SDRs or when the  correct  SDR
242              cannot be loaded.
243

TIME OPTIONS

245       By  IPMI definition, all IPMI times and timestamps are stored in local‐
246       time. However, in many situations, the timestamps will not be stored in
247       localtime.  Whether  or  not  a  system  truly stored the timestamps in
248       localtime varies on many factors, such as the vendor, BIOS, and operat‐
249       ing  system.   The  following options will allow the user to adjust the
250       interpretation of the stored timestamps and how they should be output.
251
252       --utc-to-localtime
253              Assume all times are reported in UTC time and convert  the  time
254              to localtime before being output.
255
256       --localtime-to-utc
257              Convert all localtime timestamps to UTC before being output.
258
259       --utc-offset=SECONDS
260              Specify  a  specific  UTC offset in seconds to be added to time‐
261              stamps.  Value can range from -86400 to 86400 seconds.  Defaults
262              to 0.
263

HOSTRANGED OPTIONS

265       The following options manipulate hostranged output. See HOSTRANGED SUP‐
266       PORT below for additional information on hostranges.
267
268       -B, --buffer-output
269              Buffer hostranged output. For each node, buffer standard  output
270              until the node has completed its IPMI operation. When specifying
271              this option, data may appear to output slower to the user  since
272              the  the entire IPMI operation must complete before any data can
273              be output.  See HOSTRANGED SUPPORT below for additional informa‐
274              tion.
275
276       -C, --consolidate-output
277              Consolidate hostranged output. The complete standard output from
278              every node specified will be consolidated  so  that  nodes  with
279              identical  output are not output twice. A header will list those
280              nodes with the consolidated output. When this option  is  speci‐
281              fied,  no  output  can  be seen until the IPMI operations to all
282              nodes has completed. If the  user  breaks  out  of  the  program
283              early,  all  currently  consolidated  output will be dumped. See
284              HOSTRANGED SUPPORT below for additional information.
285
286       -F NUM, --fanout=NUM
287              Specify multiple host fanout. A  "sliding  window"  (or  fanout)
288              algorithm is used for parallel IPMI communication so that slower
289              nodes or timed out nodes will not impede parallel communication.
290              The maximum number of threads available at the same time is lim‐
291              ited by the fanout. The default is 64.
292
293       -E, --eliminate
294              Eliminate hosts determined as undetected  by  ipmidetect.   This
295              attempts to remove the common issue of hostranged execution tim‐
296              ing out due to several nodes being removed  from  service  in  a
297              large  cluster.  The  ipmidetectd  daemon must be running on the
298              node executing the command.
299
300       --always-prefix
301              Always prefix output, even if only one host is specified or com‐
302              municating  in-band. This option is primarily useful for script‐
303              ing purposes. Option will be ignored if specified  with  the  -C
304              option.
305

HOSTRANGED SUPPORT

307       Multiple hosts can be input either as an explicit comma separated lists
308       of hosts or a range of hostnames in  the  general  form:  prefix[n-m,l-
309       k,...],  where  n < m and l < k, etc. The later form should not be con‐
310       fused with regular expression character classes (also denoted  by  []).
311       For example, foo[19] does not represent foo1 or foo9, but rather repre‐
312       sents a degenerate range: foo19.
313
314       This range syntax is meant only as a convenience  on  clusters  with  a
315       prefixNN  naming  convention  and specification of ranges should not be
316       considered necessary -- the list foo1,foo9 could be specified as  such,
317       or by the range foo[1,9].
318
319       Some examples of range usage follow:
320           foo[01-05] instead of foo01,foo02,foo03,foo04,foo05
321           foo[7,9-10] instead of foo7,foo9,foo10
322           foo[0-3] instead of foo0,foo1,foo2,foo3
323
324       As a reminder to the reader, some shells will interpret brackets ([ and
325       ]) for pattern matching. Depending on your shell, it may  be  necessary
326       to enclose ranged lists within quotes.
327
328       When  multiple  hosts  are specified by the user, a thread will be exe‐
329       cuted for each host in parallel up to the configured fanout (which  can
330       be  adjusted via the -F option). This will allow communication to large
331       numbers of nodes far more quickly than if done in serial.
332
333       By default, standard output from each node  specified  will  be  output
334       with the hostname prepended to each line. Although this output is read‐
335       able in many situations, it may be difficult to read  in  other  situa‐
336       tions.  For  example, output from multiple nodes may be mixed together.
337       The -B and -C options can be used to change this default.
338
339       In-band IPMI Communication will be used when the  host  "localhost"  is
340       specified.  This  allows  the  user  to add the localhost into the hos‐
341       tranged output.
342

GENERAL TROUBLESHOOTING

344       Most often, IPMI problems are due to configuration problems.
345
346       IPMI over  LAN  problems  involve  a  misconfiguration  of  the  remote
347       machine's  BMC.  Double check to make sure the following are configured
348       properly in the remote machine's BMC: IP address, MAC  address,  subnet
349       mask,  username,  user enablement, user privilege, password, LAN privi‐
350       lege, LAN enablement, and allowed authentication type(s). For IPMI  2.0
351       connections,  double  check  to make sure the cipher suite privilege(s)
352       and K_g key are configured properly. The  ipmi-config(8)  tool  can  be
353       used to check and/or change these configuration settings.
354
355       Inband  IPMI  problems  are  typically  caused by improperly configured
356       drivers or non-standard BMCs.
357
358       In addition to the troubleshooting tips below, please  see  WORKAROUNDS
359       below to also if there are any vendor specific bugs that have been dis‐
360       covered and worked around.
361
362       Listed below are many of the common issues  for  error  messages.   For
363       additional  support, please e-mail the <freeipmi-users@gnu.org> mailing
364       list.
365
366       "username invalid" - The username entered (or a NULL username  if  none
367       was  entered)  is  not  available on the remote machine. It may also be
368       possible the remote BMC's username configuration is incorrect.
369
370       "password invalid" - The password entered (or a NULL password  if  none
371       was  entered)  is not correct. It may also be possible the password for
372       the user is not correctly configured on the remote BMC.
373
374       "password verification timeout" - Password verification has timed  out.
375       A  "password  invalid"  error  (described  above) or a generic "session
376       timeout" (described below) occurred.  During this point in the protocol
377       it cannot be differentiated which occurred.
378
379       "k_g  invalid"  -  The  K_g  key entered (or a NULL K_g key if none was
380       entered) is not correct. It may also be possible the  K_g  key  is  not
381       correctly configured on the remote BMC.
382
383       "privilege level insufficient" - An IPMI command requires a higher user
384       privilege than the one authenticated with. Please try  to  authenticate
385       with a higher privilege. This may require authenticating to a different
386       user which has a higher maximum privilege.
387
388       "privilege level cannot be obtained for  this  user"  -  The  privilege
389       level  you are attempting to authenticate with is higher than the maxi‐
390       mum allowed for this user. Please try again with a lower privilege.  It
391       may  also be possible the maximum privilege level allowed for a user is
392       not configured properly on the remote BMC.
393
394       "authentication type unavailable for attempted privilege level"  -  The
395       authentication  type you wish to authenticate with is not available for
396       this privilege level. Please try again with an alternate authentication
397       type  or  alternate privilege level. It may also be possible the avail‐
398       able authentication types you can authenticate with are  not  correctly
399       configured on the remote BMC.
400
401       "cipher suite id unavailable" - The cipher suite id you wish to authen‐
402       ticate with is not available on the remote BMC. Please try  again  with
403       an  alternate  cipher  suite  id. It may also be possible the available
404       cipher suite ids are not correctly configured on the remote BMC.
405
406       "ipmi 2.0 unavailable" - IPMI 2.0 was  not  discovered  on  the  remote
407       machine. Please try to use IPMI 1.5 instead.
408
409       "connection  timeout"  - Initial IPMI communication failed. A number of
410       potential errors are possible, including an invalid hostname specified,
411       an  IPMI  IP  address  cannot  be  resolved, IPMI is not enabled on the
412       remote server, the network connection is bad, etc. Please  verify  con‐
413       figuration and connectivity.
414
415       "session  timeout"  - The IPMI session has timed out. Please reconnect.
416       If this error occurs often, you may wish to increase the retransmission
417       timeout. Some remote BMCs are considerably slower than others.
418
419       "device  not  found"  - The specified device could not be found. Please
420       check configuration or inputs and try again.
421
422       "driver timeout" - Communication with the driver or  device  has  timed
423       out. Please try again.
424
425       "message  timeout"  - Communication with the driver or device has timed
426       out. Please try again.
427
428       "BMC busy" - The BMC is currently busy. It may be  processing  informa‐
429       tion  or have too many simultaneous sessions to manage. Please wait and
430       try again.
431
432       "could not find inband device" - An inband device could not  be  found.
433       Please  check configuration or specify specific device or driver on the
434       command line.
435
436       "driver timeout" - The inband driver has timed out communicating to the
437       local  BMC  or  service  processor. The BMC or service processor may be
438       busy or (worst case) possibly non-functioning.
439
440       "internal IPMI error" - An IPMI error has occurred that  FreeIPMI  does
441       not  know  how  to  handle.  Please  e-mail <freeipmi-users@gnu.org> to
442       report the issue.
443

WORKAROUNDS

445       With so many different vendors implementing their own  IPMI  solutions,
446       different  vendors  may implement their IPMI protocols incorrectly. The
447       following describes a number of workarounds currently available to han‐
448       dle  discovered compliance issues. When possible, workarounds have been
449       implemented so they will be transparent to the user. However, some will
450       require the user to specify a workaround be used via the -W option.
451
452       The hardware listed below may only indicate the hardware that a problem
453       was discovered on. Newer versions of  hardware  may  fix  the  problems
454       indicated  below.  Similar machines from vendors may or may not exhibit
455       the same problems. Different vendors may license  their  firmware  from
456       the  same IPMI firmware developer, so it may be worthwhile to try work‐
457       arounds listed below even if your motherboard is not listed.
458
459       If you believe your hardware has an additional  compliance  issue  that
460       needs a workaround to be implemented, please contact the FreeIPMI main‐
461       tainers on <freeipmi-users@gnu.org> or <freeipmi-devel@gnu.org>.
462
463       assumeio - This workaround flag will assume inband interfaces  communi‐
464       cate  with  system  I/O rather than being memory-mapped. This will work
465       around systems that report invalid base addresses. Those  hitting  this
466       issue  may see "device not supported" or "could not find inband device"
467       errors.  Issue observed on HP ProLiant DL145 G1.
468
469       spinpoll - This workaround flag will inform some inband  drivers  (most
470       notably  the  KCS driver) to spin while polling rather than putting the
471       process to sleep. This may significantly improve the wall clock running
472       time  of  tools because an operating system scheduler's granularity may
473       be much larger than the time it takes to perform a single IPMI  message
474       transaction.  However,  by spinning, your system may be performing less
475       useful work by not contexting out the tool for a more useful task.
476
477       authcap - This workaround flag will  skip  early  checks  for  username
478       capabilities,  authentication  capabilities,  and K_g support and allow
479       IPMI authentication to succeed. It  works  around  multiple  issues  in
480       which the remote system does not properly report username capabilities,
481       authentication capabilities, or K_g status. Those  hitting  this  issue
482       may  see  "username  invalid",  "authentication  type  unavailable  for
483       attempted privilege level", or "k_g invalid" errors.  Issue observed on
484       Asus  P5M2/P5MT-R/RS162-E4/RX4,  Intel  SR1520ML/X38ML,  and  Sun  Fire
485       2200/4150/4450 with ELOM.
486
487       nochecksumcheck - This workaround flag will tell FreeIPMI to not  check
488       the  checksums  returned  from  IPMI command responses. It works around
489       systems that return invalid checksums due to implementation errors, but
490       the  packet  is otherwise valid. Users are cautioned on the use of this
491       option, as it removes validation of packet integrity  in  a  number  of
492       circumstances.  However,  it  is unlikely to be an issue in most situa‐
493       tions. Those hitting this issue may see "connection timeout",  "session
494       timeout",  or  "password verification timeout" errors. On IPMI 1.5 con‐
495       nections, the "noauthcodecheck" workaround may also needed  too.  Issue
496       observed  on  Supermicro  X9SCM-iiF, Supermicro X9DRi-F, and Supermicro
497       X9DRFR.
498
499       idzero - This workaround flag  will  allow  empty  session  IDs  to  be
500       accepted by the client. It works around IPMI sessions that report empty
501       session IDs to the client. Those hitting this issue  may  see  "session
502       timeout" errors. Issue observed on Tyan S2882 with M3289 BMC.
503
504       unexpectedauth  -  This  workaround flag will allow unexpected non-null
505       authcodes to be checked as though they were expected. It  works  around
506       an  issue  when  packets contain non-null authentication data when they
507       should be null due to disabled per-message authentication.  Those  hit‐
508       ting  this  issue  may  see "session timeout" errors. Issue observed on
509       Dell PowerEdge 2850,SC1425. Confirmed fixed on newer firmware.
510
511       forcepermsg - This workaround flag will force  per-message  authentica‐
512       tion  to  be used no matter what is advertised by the remote system. It
513       works around an issue when per-message authentication is advertised  as
514       disabled on the remote system, but it is actually required for the pro‐
515       tocol. Those hitting this  issue  may  see  "session  timeout"  errors.
516       Issue observed on IBM eServer 325.
517
518       endianseq  -  This  workaround flag will flip the endian of the session
519       sequence numbers to allow the session to continue  properly.  It  works
520       around  IPMI  1.5  session  sequence numbers that are the wrong endian.
521       Those hitting this  issue  may  see  "session  timeout"  errors.  Issue
522       observed  on  some  Sun  ILOM  1.0/2.0  (depends  on  service processor
523       endian).
524
525       noauthcodecheck - This workaround flag will tell FreeIPMI to not  check
526       the  authentication  codes returned from IPMI 1.5 command responses. It
527       works around systems that return invalid authentication  codes  due  to
528       hashing  or  implementation  errors.  Users are cautioned on the use of
529       this option, as it removes an authentication check verifying the valid‐
530       ity of a packet. However, in most organizations, this is unlikely to be
531       a security issue. Those hitting this issue may  see  "connection  time‐
532       out",  "session  timeout",  or  "password verification timeout" errors.
533       Issue observed on Xyratex FB-H8-SRAY, Intel  Windmill,  Quanta  Winter‐
534       fell, and Wiwynn Windmill.
535
536       intel20  - This workaround flag will work around several Intel IPMI 2.0
537       authentication issues. The issues covered include padding of usernames,
538       and  password  truncation  if  the  authentication  algorithm  is HMAC-
539       MD5-128. Those hitting this issue may see "username invalid", "password
540       invalid",  or  "k_g  invalid" errors. Issue observed on Intel SE7520AF2
541       with Intel Server Management Module (Professional Edition).
542
543       supermicro20 - This workaround flag will work around several Supermicro
544       IPMI  2.0  authentication  issues  on  motherboards  w/  Peppercon IPMI
545       firmware. The issues covered include handling invalid length  authenti‐
546       cation  codes.  Those  hitting  this  issue  may see "password invalid"
547       errors.  Issue observed on Supermicro H8QME with SIMSO  daughter  card.
548       Confirmed fixed on newerver firmware.
549
550       sun20 - This workaround flag will work work around several Sun IPMI 2.0
551       authentication issues. The issues covered include invalid lengthed hash
552       keys,  improperly  hashed keys, and invalid cipher suite records. Those
553       hitting this issue may see "password invalid" or  "bmc  error"  errors.
554       Issue  observed  on Sun Fire 4100/4200/4500 with ILOM.  This workaround
555       automatically includes the "opensesspriv" workaround.
556
557       opensesspriv - This workaround flag will slightly alter FreeIPMI's IPMI
558       2.0 connection protocol to workaround an invalid hashing algorithm used
559       by the remote system. The privilege level sent during the Open  Session
560       stage of an IPMI 2.0 connection is used for hashing keys instead of the
561       privilege level sent during the RAKP1 connection stage.  Those  hitting
562       this  issue may see "password invalid", "k_g invalid", or "bad rmcpplus
563       status code" errors.  Issue observed on Sun  Fire  4100/4200/4500  with
564       ILOM, Inventec 5441/Dell Xanadu II, Supermicro X8DTH, Supermicro X8DTG,
565       Intel S5500WBV/Penguin Relion 700,  Intel  S2600JF/Appro  512X,  Quanta
566       QSSC-S4R/Appro  GB812X-CN, and Dell C5220. This workaround is automati‐
567       cally triggered with the "sun20" workaround.
568
569       integritycheckvalue - This workaround flag will work around an  invalid
570       integrity  check  value  during  an IPMI 2.0 session establishment when
571       using Cipher Suite ID 0. The integrity check value should be 0  length,
572       however  the  remote motherboard responds with a non-empty field. Those
573       hitting this issue may see "k_g  invalid"  errors.  Issue  observed  on
574       Supermicro  X8DTG,  Supermicro X8DTU, and Intel S5500WBV/Penguin Relion
575       700, and Intel S2600JF/Appro 512X.
576
577       assumemaxsdrrecordcount - This workaround will inform  SDR  reading  to
578       stop  reading  after  a  known  maximum number of SDR records have been
579       read. This will work around systems that have mis-implemented SDR read‐
580       ing  functions.  Those  hitting  this  issue  may see "SDR record count
581       invalid" errors. Issue observed on unspecified Inspur motherboard.
582
583       skipchecks - This workaround option will skip FRU checksum checks. Some
584       FRUs  have incorrect checksums, but the FRU data is correct. Those hit‐
585       ting this issue may see "checksum invalid" errors in their FRU  output.
586       Output  may  be unknown, pray for the best. This option is confirmed to
587       work around compliances issues on Inventec 5441/Dell  Xanadu  II,  Dell
588       Poweredge R610, and Dell Poweredge R710 motherboards.
589
590       No IPMI 1.5 Support - Some motherboards that support IPMI 2.0 have been
591       found to not support IPMI 1.5. Those hitting this issue may  see  "ipmi
592       2.0  unavailable"  or  "connection  timeout"  errors. This issue can be
593       worked around by using IPMI 2.0  instead  of  IPMI  1.5  by  specifying
594       --driver-type=LAN_2_0.  Issue observed on a number of HP and Supermicro
595       motherboards.
596

OEM INTERPRETATION

598       The following motherboards are confirmed to have atleast  some  support
599       by  the --interpret-oem-data option. While highly probable the OEM data
600       interpretations would work across other motherboards by the same  manu‐
601       facturer,  there  are no guarantees. Some of the motherboards below may
602       be rebranded by vendors/distributors.

IPMI-FRU KNOWN ISSUES

624       Not all language codes are supported in ipmi-fru.  If  additional  lan‐
625       guage code support is required please contact the FreeIPMI maintainers.
626

DIAGNOSTICS

628       Upon  successful  execution, exit status is 0. On error, exit status is
629       1.
630
631       If multiple hosts are specified for communication, the exit status is 0
632       if  and  only  if  all targets successfully execute. Otherwise the exit
633       status is 1.
634

KNOWN ISSUES

636       On older operating systems, if you input your username,  password,  and
637       other  potentially  security  relevant information on the command line,
638       this information may be discovered by other users when using tools like
639       the  ps(1) command or looking in the /proc file system. It is generally
640       more secure to input password information with options like the  -P  or
641       -K  options.  Configuring security relevant information in the FreeIPMI
642       configuration file would also be an appropriate way to hide this infor‐
643       mation.
644
645       In  order  to  prevent  brute force attacks, some BMCs will temporarily
646       "lock up" after a number of remote authentication errors. You may  need
647       to  wait awhile in order to this temporary "lock up" to pass before you
648       may authenticate again.
