ipmitool
ipmitool - utility for controlling IPMI-enabled devices
Configuring IPMI under Linux using ipmitool - Thomas-Krenn-Wiki - https://www.thomas-krenn.com/en/wiki/Configuring_IPMI_under_Linux_using_ipmitool
Installation
Easy way:
yum install ipmitool apt-get install ipmitool
# for ipmipower tool: yum install freeipmi apt-get install freeipmi-tools
Harder way (source code): (http://sourceforge.net/projects/ipmitool/)
yum install gcc make compat-glibc-headers wget http://downloads.sourceforge.net/project/ipmitool/ipmitool/1.8.14/ipmitool-1.8.14.tar.bz2 tar -jvxf ipmitool-1.8.14.tar.bz2 ipmitool-1.8.14 ./configure make clean make && make install
Load kernel module
modprobe ipmi_devintf # CentOS 6.5 module name
Should create: /dev/ipmi0
Usage

Get Power Status
$ ipmipower -h 10.10.10.10 -u ADMIN -p ADMIN -s
10.10.10.10: on
10.10.10.10: 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 10.10.10.10 -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 10.10.10.10 -U ADMIN -P ADMIN power on
ipmitool -H 10.10.10.10 -U ADMIN -P ADMIN power off
ipmitool -H 10.10.10.10 -U ADMIN -P ADMIN power cycle
ipmipower -h 10.10.10.10 -u ADMIN -p ADMIN --on # -n
ipmipower -h 10.10.10.10 -u ADMIN -p ADMIN --off # -f
ipmipower -h 10.10.10.10 -u ADMIN -p ADMIN --cycle # -c
ipmipower -h 10.10.10.10 -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 10.10.10.10 ipmitool lan set 1 netmask 255.255.255.0 ipmitool lan set 1 defgw ipaddr 10.10.10.1
Change to Dynamic Address:
ipmitool lan set 1 ipsrc dhcp # reset firmware: ipmitool mc reset cold
Ref: [1]
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
Set Next Boot Device
Get Current Boot Device
Get the current boot device
ipmitool -H $IPMI_HOST -U $IPMI_USER chassis bootparam get 5
Should likey list something like:
- BIOS PC Compatible (legacy) boot
---
Before setting PXE:
Boot Flags : - Boot Flag Invalid - Options apply to only next boot - BIOS PC Compatible (legacy) boot - Boot Device Selector : No override
After setting PXE:
Boot Flags : - Boot Flag Valid - Options apply to only next boot - BIOS PC Compatible (legacy) boot - Boot Device Selector : Force PXE
---
For reference: [1]
bootparam
Get or set various system boot option parameters.
get
Get boot parameter. Currently supported values for are:
0 - Set In Progress
1 - Service Partition Selector
2 - Service Partition Scan
3 - BMC Boot Flag Valid Bit Clearing
4 - Boot Info Acknowledge
5 - Boot Flags
6 - Boot Initiator Info
7 - Boot Initiator Mailbox
Note: 5 is really the only option that returns anything of interest
Force PXE
Set Boot Device to force_pxe [2]
ipmitool chassis bootparam set bootflag force_pxe
Other options:
force_pxe : Force PXE boot force_disk : Force boot from default Hard-drive force_safe : Force boot from default Hard-drive, request Safe Mode force_diag : Force boot from Diagnostic Partition force_cdrom : Force boot from CD/DVD force_bios : Force boot into BIOS Setup
---
If you want it to persist: options=persistent
ipmitool chassis bootdev cdrom options=persistent
---
If you want UEFI:
ipmitool chassis bootdev pxe options=efiboot #or ipmitool chassis bootdev pxe options=efiboot,persistent
IPMIv2 LanPlus
Use IPMIv2 with LanPlus:
ipmitool -I lanplus ...
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 38 00111000
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
Password
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)

Issues
# ipmitool lan print Could not open device at /dev/ipmi0 or /dev/ipmi/0 or /dev/ipmidev/0: No such file or directory
Driver not loaded, or system does not support. If driver was just not loaded, try this (sometimes happens after initial install):
modprobe ipmi_devintf
