ipmitool - utility for controlling IPMI-enabled devices

Configuring IPMI under Linux using ipmitool - Thomas-Krenn-Wiki -


Easy way:

yum install ipmitool
apt-get install ipmitool
# for ipmipower tool:
yum install freeipmi
apt-get install freeipmi-tools

Harder way (source code): (

yum install gcc make compat-glibc-headers
tar -jvxf ipmitool-1.8.14.tar.bz2
make clean
make && make install

Load kernel module

modprobe ipmi_devintf    # CentOS 6.5 module name

Should create: /dev/ipmi0



Get Power Status

$ ipmipower -h -u ADMIN -p ADMIN -s on off
ipmitool -H MYSERVER -U ADMIN -P ADMIN power status

Power On and Off

ipmitool -H MYSERVER -U ADMIN -P ADMIN power on
ipmitool -H MYSERVER -U ADMIN -P ADMIN power off

Get BIOS Status

For Supermicro

ipmitool -H -U ADMIN -P ADMIN raw 0x30 0x2a
aa / fe - ok finished bios (depending on model)
72 - off
91 - Stuck at "DXE--BIOS PCI Bus Enumeration..."
94 - Stuck at "?"
...many other codes... - system in various states of bios loading

Reboot System

ipmitool -H -U ADMIN -P ADMIN power on
ipmitool -H -U ADMIN -P ADMIN power off
ipmitool -H -U ADMIN -P ADMIN power cycle
ipmipower -h -u ADMIN -p ADMIN --on  # -n
ipmipower -h -u ADMIN -p ADMIN --off  # -f
ipmipower -h -u ADMIN -p ADMIN --cycle  # -c
ipmipower -h -u ADMIN -p ADMIN -r  # --reset
ipmipower -h i-mynode -u ADMIN -p ADMIN -r --on-if-off

Note: ipmipower is part of the freeipmi-tools package

ipmi network address

ipmitool lan print
ipmitool lan print | grep "IP Address"

Change to Static Address:

ipmitool lan set 1 ipsrc static
ipmitool lan set 1 ipaddr
ipmitool lan set 1 netmask
ipmitool lan set 1 defgw ipaddr

Change to Dynamic Address:

ipmitool lan set 1 ipsrc dhcp
# reset firmware:
ipmitool mc reset cold

Sensor Data

sdr command - Print Sensor Data Repository entries and readings

# ipmitool sdr
P0 Temp          | 36 degrees C      | ok
P1 Temp          | 36 degrees C      | ok
P0 TjMax         | 86 degrees C      | ok
P1 Tjmax         | 86 degrees C      | ok

sensor command - Print detailed sensor information

# ipmitool sensor
P0 Temp          | 37.000     | degrees C  | ok    | na        | na        | na        | na        | 84.000    | na
P1 Temp          | 36.000     | degrees C  | ok    | na        | na        | na        | na        | 84.000    | na
P0 TjMax         | 86.000     | degrees C  | ok    | na        | na        | na        | na        | na        | na
P1 Tjmax         | 86.000     | degrees C  | ok    | na        | na        | na        | na        | na        | na

IPMI Reboot

ipmitool mc reset cold
ipmitool mc reset warm

Control Remote BMC

ipmitool -I lanplus -H [BMC_ADDRESS] -U USERID -P [PASSWORD] sensor

Note, my configuration was incorrect and this would timeout:

# ipmitool -I lanplus -H i-myserver -U USERID -P mypassword sensor
Error: Unable to establish IPMI v2 / RMCP+ session
Get Device ID command failed
Unable to open SDR for reading

i2c access

If you know the bus and address of a target i2c device: (server/device specific)

usage: i2c [bus=public|# [chan=#] <i2caddr> <read bytes> [write data]

Example: (temperature sensor, there is a conversion required to get to C)

# ipmitool i2c bus=1 0x3e 1 1

User List

ipmitool user list [CHANNEL_NUMBER]
# ipmitool user list 1
ID  Name             Callin  Link Auth  IPMI Msg   Channel Priv Limit
1                    true    false      true       USER
2   USERID           true    false      true       ADMINISTRATOR
3   root             true    false      false      ADMINISTRATOR


ipmitool user list
#ipmitool user set password <USERID> [PASSWORD]

Add admin user: [2]

ipmitool user list
ipmitool user set name 3 ADMIN
ipmitool user set password 3  # enter 'ADMIN'
ipmitool channel setaccess 1 3 link=on ipmi=on callin=on privilege=4
ipmitool user enable 3

Password is too long (> 20 bytes)
