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, indentification (i.e. LED control), and status. See
OPTIONS below for all chassis management options available.
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).
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
ipmipower(8).
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
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
information 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
system 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
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.
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-control=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
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.
