IPMI-CHASSIS(8) System Commands IPMI-CHASSIS(8) NAME ipmi-chassis - IPMI chassis management utility SYNOPSIS ipmi-chassis [OPTION...] DESCRIPTION Ipmi-chassis is used for managing/monitoring an IPMI chassis, such as chassis power, identification (i.e. LED control), and status. See OP- TIONS below for all chassis management options available. 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). To perform IPMI chassis configuration, please see ipmi-config(8). To perform some advanced chassis management, please see bmc-device(8). For a more powerful chassis power control utility, please see ip- mipower(8). GENERAL OPTIONS The following options are general options for configuring IPMI communi- cation and executing general tool commands. -D IPMIDRIVER, --driver-type=IPMIDRIVER Specify the driver type to use instead of doing an auto selec- tion. The currently available outofband drivers are LAN and LAN_2_0, which perform IPMI 1.5 and IPMI 2.0 respectively. The currently available inband drivers are KCS, SSIF, OPENIPMI, 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 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 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 AD- MIN 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-CHASSIS OPTIONS The following options are specific to ipmi-chassis. --get-chassis-capabilities Get chassis capabilities. This command returns information on which main chassis management functions are available. --get-chassis-status Get chassis status. This command returns high level status in- formation on the chassis. --chassis-control=CONTROL Control the chassis. This command provides power-up, power-down, and reset control. Supported values: POWER-DOWN, POWER-UP, POWER-CYCLE, HARD-RESET, DIAGNOSTIC-INTERRUPT, SOFT-SHUTDOWN. --chassis-identify=IDENTIFY Set chassis identification. This command controls physical sys- tem identification, typically a LED. Supported values: TURN-OFF to turn off identification, <interval> to turn on identification for "interval" seconds, FORCE to turn on indefinitely. --get-system-restart-cause Get system restart cause. --get-power-on-hours-counter Get power on hours (POH) counter. 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. 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. EXAMPLES # ipmi-chassis --get-status Get the chassis status of the local machine. # ipmi-chassis -h ahost -u myusername -p mypassword --get-status Get the chassis status of a remote machine using IPMI over LAN. # ipmi-chassis -h mycluster[0-127] -u myusername -p mypassword --get- status Get the chassis status across a cluster using IPMI over LAN. # ipmi-chassis -h ahost -u myusername -p mypassword --chassis-con- trol=POWER-UP Power on a remote machine 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 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. REPORTING BUGS Report bugs to <freeipmi-users@gnu.org> or <freeipmi-devel@gnu.org>.
