IPMI-FRU(8)			System Commands			   IPMI-FRU(8)

NAME
       ipmi-fru	- display FRU information

SYNOPSIS
       ipmi-fru	[OPTION...]

DESCRIPTION
       Ipmi-fru	displays Field Replaceable Unit	(FRU) Information. The FRU may
       hold a variety of information, such as device information, hardware in-
       formation, serial numbers, and part numbers.

       Listed  below  are general IPMI options,	tool specific options, trouble
       shooting	information, workaround	information, examples, and  known  is-
       sues. For a general introduction	to FreeIPMI please see freeipmi(7).

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,
	      SUNBMC, and INTELDCMI.

       --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  re-
	      quests 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.  If specifying an IPv6 address and	 port,
	      use the format [ADDRESS]:PORT.

       -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 as-
	      sumed. 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 re-
	      mote 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.  De-
	      faults to	1000 milliseconds (1 second) if	not specified. The re-
	      transmission timeout cannot be larger than the session timeout.

       -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 USER
	      if not specified.

       --config-file=FILE
	      Specify an alternate configuration file.

       -W WORKAROUNDS, --workaround-flags=WORKAROUNDS
	      Specify  workarounds  to	vendor	compliance  issues.   Multiple
	      workarounds can be specified separated by	commas.	A special com-
	      mand  line  flag of "none", will indicate	no workarounds (may be
	      useful for overriding configured defaults). See WORKAROUNDS  be-
	      low 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-FRU OPTIONS
       The following options are specific to ipmi-fru.

       -e, --device-id=IDNUM
	      Specify a	specific FRU device ID.

       -v, --verbose
	      Increase verbosity in output to include additional output.

       --bridge-fru
	      By  default, FRU entries on other	satellite controllers will not
	      be read by  default.  Bridging  may  not	work  on  some	inter-
	      faces/driver types.

       --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.

       --fru-file=FILENAME
	      Output  data from	the specified FRU binary file instead of read-
	      ing FRU data off of a board.

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.

       --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.

       --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.

TIME OPTIONS
       By  IPMI	definition, all	IPMI times and timestamps are stored in	local-
       time. However, in many situations, the timestamps will not be stored in
       localtime. Whether or not a system truly	stored the timestamps  in  lo-
       caltime varies on many factors, such as the vendor, BIOS, and operating
       system.

       The  following options will allow the user to adjust the	interpretation
       of the stored timestamps	and how	they should be output.

       --utc-to-localtime
	      Assume all times are reported in UTC time	and convert  the  time
	      to localtime before being	output.

       --localtime-to-utc
	      Convert all localtime timestamps to UTC before being output.

       --utc-offset=SECONDS
	      Specify  a  specific  UTC	offset in seconds to be	added to time-
	      stamps.  Value can range from -86400 to 86400 seconds.  Defaults
	      to 0.

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) al-
	      gorithm 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 ma-
       chine'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 ipmi-config(8) tool	can be
       used to check and/or change these configuration settings.

       Inband IPMI problems are	typically caused by improperly configured dri-
       vers 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 ad-
       ditional	 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  en-
       tered)  is not correct. It may also be possible the K_g key is not cor-
       rectly 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 ci-
       pher suite ids are not correctly	configured on the remote BMC.

       "ipmi 2.0 unavailable" -	IPMI 2.0 was not discovered on the remote  ma-
       chine. 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  re-
       mote server, the	network	connection is bad, etc.	Please verify configu-
       ration 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.

       "internal IPMI error" - An IPMI error has occurred that	FreeIPMI  does
       not  know  how to handle. Please	e-mail <freeipmi-users@gnu.org>	to re-
       port the	issue.

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 in-
       dicated 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
       workarounds 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  ca-
       pabilities, 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, authenti-
       cation  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.

       nochecksumcheck	- This workaround flag will tell FreeIPMI to not check
       the checksums returned from IPMI	command	 responses.  It	 works	around
       systems that return invalid checksums due to implementation errors, but
       the  packet  is otherwise valid.	Users are cautioned on the use of this
       option, as it removes validation	of packet integrity  in	 a  number  of
       circumstances.  However,	 it  is	unlikely to be an issue	in most	situa-
       tions. Those hitting this issue may see "connection timeout",  "session
       timeout",  or  "password	verification timeout" errors. On IPMI 1.5 con-
       nections, the "noauthcodecheck" workaround may also needed  too.	 Issue
       observed	 on  Supermicro	 X9SCM-iiF, Supermicro X9DRi-F,	and Supermicro
       X9DRFR.

       idzero -	This workaround	flag will allow	empty session IDs  to  be  ac-
       cepted  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.  Is-
       sue 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 ob-
       served 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 that 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, Intel  Windmill,  Quanta  Winter-
       fell, and Wiwynn	Windmill.

       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"  er-
       rors.   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", "bad rmcpplus
       status code", or	"privilege level cannot	be obtained for	this user" er-
       rors.  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,	 Quanta	 QSSC-
       S4R/Appro  GB812X-CN,  Dell  C5220, and the OpenIPMI software BMC. 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 us-
       ing  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 Su-
       permicro	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 number  of  SDR  records  have  been
       read.  This  will  work	around	systems	that have miss-implemented SDR
       reading functions. Those	hitting	this issue may see "SDR	 record	 count
       invalid"	errors.	Issue observed on unspecified Inspur motherboard.

       skipchecks - This workaround option will	skip FRU checksum checks. Some
       FRUs  have incorrect checksums, but the FRU data	is correct. Those hit-
       ting this issue may see "checksum invalid" errors in their FRU  output.
       Output  may  be unknown,	pray for the best. This	option is confirmed to
       work around compliances issues on Inventec 5441/Dell  Xanadu  II,  Dell
       Poweredge R610, and Dell	Poweredge R710 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-type=LAN_2_0. Issue observed on	a number of HP and  Supermicro
       motherboards.

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.

       Wistron/Dell Poweredge C6220

EXAMPLES
       # ipmi-fru

       # ipmi-fru --verbose

       Get verbose FRU information of the local	machine.

       # ipmi-fru -h ahost -u myusername -p mypassword

       Get FRU information of a	remote machine using IPMI over LAN.

       # ipmi-fru -h mycluster[0-127] -u myusername -p mypassword

       Get FRU information across a cluster using IPMI over LAN.

IPMI-FRU KNOWN ISSUES
       Not  all	 language codes	are supported in ipmi-fru.  If additional lan-
       guage code support is required please contact the FreeIPMI maintainers.

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.
