Recently I’ve had an opportunity to work with SuperMicro servers that have been new to me. SuperMicro servers will be are managed remotely utilizing the IPMI interface. In this text I’ll attempt to present fundamental steps of IPMI configuration and inform about extra instruments, instructions and strategies of SuperMicro server remotely administration and monitoring utilizing IPMI.
IPMI (Intelligent Platform Management Interface) gives autonomous monitoring and administration interface built-in straight into the server and firmware. IPMI is applied as a separate server controller unbiased of an operation system, BIOS or server CPU and permits distant bodily administration.
SuperMicro IPMI Configuration through BIOS and Web Interface
IPMI configuration begins with setting the IP tackle of the interface, which should be specified within the BIOS. If the MicroServer is put in on-premise, it could be a personal IP tackle. And in case your server is positioned in public knowledge heart, you’re possible to make use of a static public IP tackle.
On SuperMicro servers, you may entry the BIOS by urgent DEL button throughout the server boot. I cannot name any particular consideration to it. Let’s proceed to the SuperMicro BIOS interface.
As you may see within the screenshot above, I switched to the IPMI menu merchandise and activated LAN configuration for the IPMI interface (Update IPMI Lan Configuration = Yes, Configuration Address Source = Static), specified the IP tackle, the subnet masks and the gateway IP tackle.
You can apply the settings by urgent F4, and the server might be restarted.
If you will have carried out it accurately, you will note the authentication window as proven beneath whenever you entry the IP tackle specified of your IPMI LAN interface in a browser.
Let’s take into account the principle IPMI options on SuperMicro server.
When shopping for a brand new SuperMicro server, the person ADMIN with the password ADMIN already exists in IPMI configuration, and you need to use these credentials to entry the IPMI internet interface. I all the time advocate to create a brand new person and take away the default one or change its password. It is extremely insecure to depart the unique credentials as they’re. You can create a brand new person or change passwords/privileges of the present customers in Configuration -> Users menu.
You can restart the IPMI card in Maintenance -> Unit Reset menu.
You can mount the OS ISO picture to put in it in your server in Virtual Media -> CD-ROM Image.
My ISO pictures are saved on the Samba server in the identical subnet the IPMI server interfaces are positioned. I specify the Samba server tackle and a path to the ISO to be mounted, then I mount the ISO and run the set up of the operation system.
You can open the distant graphic Java console of the server (KVM-over-IP) in Remote Control -> Console Redirection.
In common, the IPMI distant console (Java iKVM Viewer) is handy, however after the OS set up I normally use SSH entry the server. However, there are some conditions when it’s not potential, for instance, if the LAN interface in your server is misconfigured, disabled or there are any issues. Then the Remote Console will enable you to.
You don’t must set something in it, however I wish to observe that it has an built-in digital keyboard accessed from Virtual Media -> Virtual Keyboard menu.
grubby --args "nomodeset" --update-kernel /boot/vmlinuz-`uname -r`
After that, the Remote Console works accurately.
Using the IPMICFG Tool to Manage a SuperMicro Server
To handle servers through IPMI, SuperMicro has developed its personal device — IPMICFG.
You can obtain the ipmicfg utilizing the command:
By the time this text had been printed, the file had the identify specified above, However, I like to recommend to go to SuperMicro repository right here: ftp://ftp.supermicro.com/utility/IPMICFG/ and duplicate the URL of the particular file model.
Extract the downloaded archive to the present listing:
Then create a symbolic hyperlink to run the device simpler:
ln -s /root/IPMI*/Linux/64bit/IPMICFG-Linux.x86_64 /usr/native/sbin/ipmicfg
Now you can begin the device utilizing the ipmicfg command (the symbolic hyperlink). Lets take into account fundamental options of ipmicfg.
If you run the
ipmicfg -help command, you will note the record of all obtainable switches.
Let’s describe essentially the most helpful ipmicfg instructions:
ipmicfg -help– get assist
ipmicfg -m– exhibits the present IP and MAC tackle for the IPMI LAN interface
ipmicfg -k— exhibits the subnet masks
ipmicfg -g– exhibits gateway IP tackle
ipmicfg -fd— resets IPMI to the manufacturing unit default settings
ipmicfg -user record– exhibits the created customers and their privileges
You can change the IP tackle, subnet masks and gateway of the IPMI LAN interface:
ipmicfg -m 192.168.zero.120
ipmicfg -k 255.255.255.zero
ipmicfg -g 192.168.zero.1
To create a brand new IPMI person and set a password:
ipmicfg -user add
ipmicfg -user add 6 ipmiusr [email protected]_d four
Thus, we now have created a person with the identify
ipmiusr and the password
[email protected]_d having administrator privileges.
You can record IPMI customers and their permissions utilizing the instructions:
ipmicfg -user record
ipmicfg -user assist
To change (reset) an IPMI person password, use the command:
ipmicfg -user setpwd
Here are some extra examples of utilizing the ipmicfg device:
ipmicfg -hostname [value]— units a hostname for IPMI LAN interface
ipmicfg -r— restarts IPMI card
Hardware Monitoring on SuperMicro Servers Using IPMI & IPMICFG
SuperMicro Server Monitoring Using IPMI
It is kind of straightforward to observe operation of the SuperMicro server utilizing IPMI. You can discover full details about your server in System -> Hardware Information.
You can view the CPU, reminiscence and followers state in Server Health -> Sensor Readings.
To make it extra handy, you may change sensor classes, e. g., choose temperature sensors:
Or voltage sensors:
Since, there aren’t any points with our server now, all sensors (temperature, energy, and many others.) are within the inexperienced zone. If the temperature will increase or any voltage issues happen, inexperienced rectangles will turn into crimson and warn you to verify your server.
Checking SuperMicro Server Hardware Using IPMICFG
To verify the state of energy provide items:
# ipmicfg -pminfo
[SlaveAddress = 78h] [Module 1] Item | Value ---- | ----- Status | [STATUS OK] (00h) Input Voltage | 217.5 V Input Current | 1.06 A Main Output Voltage | 12.28 V Main Output Current | 17.93 A Temperature 1 | 22C/73F Temperature 2 | 23C/70F Fan 1 | 2064 RPM Fan 2 | 2032 RPM Main Output Power | 220 W Input Power | 228 W PMBus Revision | 0x22 PWS Serial Number | P2K4FBA022T01321 PWS Module Number | PWS-2K04F-1R PWS Revision | REV1.zero Current Sharing Control | PEC error [SlaveAddress = 7Ah] [Module 2] Item | Value ---- | ----- Status | [STATUS OK] (00h) Input Voltage | 217.5 V Input Current | 1.09 A Main Output Voltage | 12.30 V Main Output Current | 18.09 A Temperature 1 | 24C/75F Temperature 2 | 22C/72F Fan 1 | 2064 RPM Fan 2 | 2064 RPM Main Output Power | 223 W Input Power | 234 W PMBus Revision | 0x22 PWS Serial Number | P2K4FBA022T01323 PWS Module Number | PWS-2K04F-1R PWS Revision | REV1.zero Current Sharing Control | PEC error
To verify the CPU temperature:
# ipmicfg -nm oemgettemp
You also can view the fan operation mode and alter it if wanted. To verify the state and configuration of the fan:
# ipmicfg -fan
Current Fan Speed Mode is [ PUE2 Optimal Mode ] Supported Fan modes: zero:Standard 1:Full three:PUE2 Optimal four:Heavy IO
To change the fan operation mode:
ipmicfg -fan three
To view the details about IPMI model and firmware:
# ipmicfg -nm deviceid
Device ID = 50h Firmware Version = four.1.four.54 IPMI Version = 2.000000 Manufacturer ID = 57 01 00 Product ID Minor Ver = Greenlow platform Implemented DCMI model = DCMI not applied/enabled Firmware applied model = NM Revision four.zero Image Flag = operational picture 1 uncooked = 50 01 13 24 02 21 57 12 00 19 0b 34 05 40 01
To get the details about all sensors:
Here we see some extra columns that show the data on the higher and decrease sensor values (limits).
Also, there are a whole lot of instruments you need to use for monitoring and make the method computerized, e.g., utilizing Nagios, Zabbix, and many others. We gained’t describe it right here since we take into account the principle options of IPMI. However, in case you are taken with IPMI monitoring, you may go away a remark and maybe sooner or later we’ll cowl this subject.
