NAME

       ipmi-dcmi - IPMI DCMI utility

SYNOPSIS

       ipmi-dcmi [OPTION...]

DESCRIPTION

       Ipmi-dcmi is used to execute Data Center Manageability Interface (often referred to as DCM
       or DCMI) IPMI extension commands. DCMI extensions include support for asset management and
       power usage management. Most will be interested in DCMI for its power management features.
       By configuring an exception action, power limit, and correction time limit, power usage in
       a  data  center can be managed more affectively. Please see --set-power-limit option below
       for more information.  DCMI can also be  configured  using  the  dcmi  category  in  ipmi-
       config(8).  The DCMI specification encompasses many traditional IPMI features that are not
       implemented directly in this tool. Please see  ipmiconsole(8)  for  Serial-over-LAN  (SOL)
       support,  ipmi-chassis(8)  for power status, power control, identification, and ACPI power
       state information, ipmipower(8) for power status and power control, ipmi-sel(8) for System
       Event  Log  (SEL)  information,  bmc-info(8)  for  device  and  globally  unique ID (guid)
       information, ipmi-sensors(8) for sensor readings, and ipmi-config(8) for configuration.

       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).

GENERAL OPTIONS

       The following options are general options for configuring IPMI communication and executing
       general tool commands.

       -D IPMIDRIVER, --driver-type=IPMIDRIVER
              Specify  the  driver type to use instead of doing an auto selection.  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 requests to.

       -h IPMIHOST1,IPMIHOST2,..., --hostname=IPMIHOST1[:PORT],IPMIHOST2[:PORT],...
              Specify the remote host(s) to communicate with. Multiple hostnames 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
              ADMIN 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 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 confidentiality algorithms to use  for  IPMI  2.0
              communication.  The  authentication  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 ADMIN 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 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

       --set-power-limit
              Set    power    limit    configuration.   Can   specify   configuration   via   the
              --exception-actions,    --power-limit-requested,    --correction-time-limit,    and
              --correction-time-limit  options listed below. If one or more options below are not
              specified, current configuration will be utilized.

       --exception-actions=BITMASK
              Specify exception actions for set power limit configuration. Special case allowable
              values: NO_ACTION, HARD_POWER_OFF_SYSTEM, LOG_EVENT_TO_SEL_ONLY. Other values (e.g.
              0x02 through 0x10) are OEM dependent. Used with the --set-power-limit option.

       --power-limit-requested=WATTS
              Specify power limit for set power limit configuration. Input is specified in watts.
              Used with the --set-power-limit option.

       --correction-time-limit=MILLISECONDS
              Specify  correction  time  limit  for  set  power  limit  configuration.   Input is
              specified in milliseconds. Used with the --set-power-limit option.

       --activate-deactivate-power-limit=OPERATION
              Activate or deactivate power limit. Allowed values: ACTIVATE, DEACTIVATE.

       --interpret-oem-data
              Attempt to interpret OEM data, such as event  data,  sensor  readings,  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 interpretations.

TIME OPTIONS

       By IPMI definition, all IPMI times and timestamps are stored  in  localtime.  However,  in
       many  situations,  the timestamps will not be stored in localtime. Whether or not a system
       truly stored the timestamps in localtime 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 timestamps.  Value can
              range from -86400 to 86400 seconds. Defaults to 0.

HOSTRANGED OPTIONS

       The following options manipulate hostranged  output.  See  HOSTRANGED  SUPPORT  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 information.

       -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  specified, 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
              limited 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 timing 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 communicating  in-band.
              This  option  is primarily useful for scripting 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 confused with  regular  expression  character  classes  (also
       denoted  by  []).  For  example,  foo[19]  does  not  represent  foo1  or foo9, but rather
       represents 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 executed 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 readable in many situations, it may be
       difficult to read in other situations. 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 hostranged 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   privilege,  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 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 discovered 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 maximum 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  available  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 authenticate 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 configuration 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 information 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 report 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  handle 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 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  maintainers  on  <freeipmi-users@gnu.org>  or
       <freeipmi-devel@gnu.org>.

       assumeio  - This workaround flag will assume inband interfaces communicate 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.

       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 situations. Those
       hitting  this  issue  may  see  "connection  timeout",  "session  timeout",  or  "password
       verification  timeout"  errors.  On IPMI 1.5 connections, 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 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 hitting 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 authentication 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 protocol. 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 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 validity of
       a packet. However, in most organizations, this is unlikely to be a security  issue.  Those
       hitting  this  issue  may  see  "connection  timeout",  "session  timeout",  or  "password
       verification timeout" errors.  Issue  observed  on  Xyratex  FB-H8-SRAY,  Intel  Windmill,
       Quanta Winterfell, 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  authentication 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.

       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 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  manufacturer,  there  are  no  guarantees. Some of the
       motherboards below may be rebranded by vendors/distributors.

       Currently None

EXAMPLES

       # ipmi-dcmi --get-power-limit

       Get power limit of the local machine.

       # ipmi-dcmi -h ahost -u myusername -p mypassword --get-power-limit

       Get power limit of a remote machine using IPMI over LAN.

       # ipmi-dcmi -h mycluster[0-127] -u myusername -p mypassword --get-power-limit

       Get power limit across a cluster using IPMI over LAN.

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 information.

       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.
