Machines

A machines is a physical server that is registered with the cloud management platform for IPMI information and can be fully managed and controlled by the cloud management platform. Physical machines are used to create baremetal devices, and baremetal exclusively occupies machines resources.

The machines supports nano-managed servers including Dell, HP, Huawei, Wave, Lenovo, Supermicro and other mainstream x86 server vendors and models.

Entry: In the cloud management platform click on the top left corner navigation menu, and click “Compute/Physical Resources/Machines” menu item in the left menu bar that pops up to enter the Machines page.

• The top right of the list will show the total number of machines and the number of machines that are running, shutdown, operation failed, and unknown.

  

View the list of machiness

This function is used to view the information of the machines list.

1. In the cloud management platform, click on the top left corner of navigation menu, and click “ComputePhysical Resources/Machines” menu item in the left menu bar that pops up to enter the Machines page.
2. Check the following parameters.
   • Enabled: Indicates whether the machines can be used to create baremetal. Only machiness in the enabled state can create baremetal.
   • Status: The operational status of the machines.
   • IP: Including the management IP and out-of-band IP of the machines, the out-of-band IP is the IP address of IPMI.
   • SN: Serial number, etc.
   • Assignment: Shows whether the machines has been assigned to create baremetal, here the name of the baremetal created by the specific machines is displayed.
   • Initial Account: Get the user name and password to connect to the machines.
   • IPMI: Includes IPMI user name, IPMI password and IPMI IP.
   • Maintenance mode: Check whether the machines is in maintenance mode. A machines that is in maintenance mode is in the yunionos minisystem.

Add machines

Currently OneCloud platform supports four ways to add machiness, please select the specific way to add according to the following figure.

• Hosting: Used to host a machines with an existing OS, a baremetal record will be created at the same time after successful hosting.
• Pre-registration: Used to pre-shelf servers that are not configured with BMC information. Through the pre-registration function, the MAC address of the server and the BMC information that needs to be configured are provided. After the server is set up for PXE boot and powered on, the Baremetal service of OneCloud platform will respond to the PXE request initiated by the server with the matching MAC address, and guide the server to load the YunionOS small system, collect the server information and reset the BMC information to complete the registration of the machines.
• ISO Boot Registration: Used to immediately boot servers with configured BMC information. This method does not require the server to be in a DHCP Relay network environment, but requires the server to support the RedFish function. This method does not require the server to be in a DHCP Relay network environment, but it does require the server to support RedFish. The Redfish API verifies the BMC configuration information and guides the server to load the YunionOS minisystem to collect more server configuration information.
• PXE Boot Registration: Used to immediately boot a server with BMC information configured. This method requires the server to be in a DHCP Relay network environment and set the server to PXE boot, verify the BMC configuration information via IPMI, boot the server to load the YunionOS minisystem, and collect more server configuration information.

ISO Boot Registration

This function is used to immediately register and boot a server with BMC information configured. This function does not require the server to be in a DHCP Relay network environment, but does require the server to support the RedFish feature.

1. On the Baremetal Hosts page, click the “Add” button to enter the Add Baremetal Hosts page.

2. Select the specified domain and the add method as “ISO Boot Registration”, which supports the following two methods of ISO Boot Registration.

   • entry: Configure the following parameters.
     • Specify Domains: Select the domain to which the machines belongs.
     • Baremetal Hosts name: Set the name of the physical server.

     • IPMI User Name: Enter the IPMI user name that has been configured on the server.
     • IPMI Password: Enter the IPMI password information that has been configured on the server. If the BMC information entered is incorrect, the bootstrap registration cannot be completed correctly.
     • Management Port IP: Select the IP subnet. If you want to specify a static IP, click the “Manually Configure IP” button to set the IP address and click the “OK” button. Since ISO bootstrap registration is applicable to environments without DHCP Relay, users must configure the IP subnet or IP address information that provides access to the server management port.
     • Registration only without boot: boot into YunionOS without reboot, after checking this item, only part of the server information is collected, the server cannot be used to create baremetal at this time, it is necessary to synchronize hardware configuration operations to make it officially put into production use.
   • Template import: Import of template files in XLSX format with machines registration information is supported.

     • To import machines information, you need to follow a predefined format, so please download the template first.

3. Click the “OK” button to complete the boot registration.

Pre-registration

This function is used to pre-shelf the server that is not configured with BMC information. The pre-registration operation only configures the relevant information, and the server will be set up for PXE boot and power up before it is actually boot registered to the cloud management platform. Requires the server to be in a DHCP Relay environment.

  • Among them, MAC address and name are required, other parameters can be omitted without filling.
  • For example: ee:b3:f4:48:1c:f5,gpuhost01,192.168.1.1,root,admin123
  • E.g. ee:b3:f4:48:1c:f5,gpuhost01,,, – omitted IPMI address, IPMI username and IPMI password
  • When the entry is complete, click the “OK” button.
