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.  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 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   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.

       --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

       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,  Quanta  QSSC-S4R/Appro GB812X-CN, and Dell C5220. 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  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  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.
