ipmitool [Options] <Order> [parameter]
in:
-
Optionsare some optional switches to set some parameters of ipmitool. -
OrderIt is the operation to be performed, such as obtaining sensor information, etc. -
parameterAre optional, they are the options and values required to specify the specific action to be performed.
Commonly used ipmitool commands
1. Obtain sensor information
ipmitool sensor get <Sensor ID>
in,
<Sensor ID>is the ID of the sensor to be obtained.
This command displays the current status of the specified sensor.
2. Display system information
ipmitool fru print
This command prints all available FRU (firmware reprogrammable unit) information in the system.
3. Power control
ipmitool power on Turn on the power ipmitool power off Turn off the power ipmitool power reset Reset the power supply，According to my understanding, there is no complete power outage，System-likereboot ipmitool power cycle 先Turn off the power，Open again
These commands are used to control the power state of the server.
4. Display event log
ipmitool sel list
This command displays the system event log.
5. Enable/disable BMC users
ipmitool user enable <userID> ipmitool user disable <userID>
These commands are used to enable or disable BMC users.
The above are some commonly used ipmitool commands and their basic usage.
More ipmitool commands and options are available throughipmitool -hCommand to view the complete help documentation.
About setting BMC or remote control server BMC commands under OS
ipmitool can remotely control BMC through IPMI-over-LAN (LAN-based IPMI protocol).
To use IPMI-over-LAN, you need to make sure that the BMC is configured and connected to the network.
Steps to connect to BMC via IPMI-over-LAN and perform remote control
1. Determine the IP address of the BMC
useipmitool lan printThe command can obtain information such as the BMC's IP address, MAC address, and subnet mask.
If the BMC does not configure the IP address, you need to physically access the server locally to configure the BMC.
2. Connect to BMC
useipmitool lan set <parameters>Command to set the BMC username, password, IP address and other information.
For example, the following command sets the IP address of the BMC to 192.168.1.100, and sets the username to admin and password to password:
ipmitool lan set 1 ipsrc static ipmitool lan set 1 ipaddr 192.168.1.100 ipmitool lan set 1 netmask 255.255.255.0 ipmitool lan set 1 defgw ipaddr 192.168.1.1 ipmitool user set name 2 admin ipmitool user set password 2 password
Notice:
Here it is assumed that the BMC uses the default LAN channel 1.
If you are using another channel, you need to1Replace with the number of the corresponding channel.
3. Enable IPMI-over-LAN function
useipmitool channel info <channel number>The command checks whether the IPMI-over-LAN function of the channel where the BMC is located is enabled.
If not enabled, you can enable it using the following command:
ipmitool channel setaccess <Channel number> 2 ipmi=on auth=off link=on privilege=4
This enables the IPMI-over-LAN function of the specified channel and makes the permission level of the IPMI session through this channel 4 (ADMINISTRATOR level).
4. Connect to remote BMC
Connect to a remote BMC using the following command:
ipmitool -H <BMC IPaddress> -U <username> -P <password> -I lanplus <Order>
Note that this is used-I lanplusOption to use the LAN-based IPMI protocol.
<Command>is the ipmitool command you want to execute.
For example:
To obtain sensor information, you can use the following command:
ipmitool -H 192.168.1.100 -U admin -P password -I lanplus sensor list
This will display the sensor list information for the remote BMC.
Summarize
The above are the basic steps for remote BMC control through ipmitool.
Please note that the access rights of the remote BMC should be restricted and can only be accessed by authorized users. In addition, you should make sure that your network security measures have been applied to ensure the security of remote access.
These are just personal experience. I hope you can give me a reference and I hope you can support me more.
