10.1.3. Completing the prerequisites and booting your firmware

Before you power on the system, ensure that you have the following items:

  • Ethernet cable
  • VGA monitor. The VGA resolution must be set to 1024x768-60Hz.
  • USB Keyboard

  • Power cords and outlet for your system.

    • PC or notebook that has IPMItool level 1.8.15 or greater. (Verifying this piece of info)
    • Bootable USB device

Complete these steps:

  1. If your system belongs in a rack, install your system into that rack. For instructions, see IBM Power Systems information at https://www.ibm.com/support/knowledgecenter/.
  2. Connect an Ethernet cable to the embedded Ethernet port next to the serial port on the back of your system. Connect the other end to your network.
  3. Connect your VGA monitor to the VGA port on back of system.
  4. Connect your USB keyboard to an available USB port.
  5. Connect the power cords to the system and plug them into the outlets.

At this point, your firmware is booting. Wait for the green LED on the power button to start flashing, indicating that it is ready to use. If your system does not have a green LED indicator light, then wait 1 to 2 minutes.

10.1.4. Setting up network connection with the firmware

To set up or enable your network connection to the baseboard management controller (BMC) firmware, use the Petitboot bootloader interface. Follow these steps:

  1. Power on your server using the power button on the front of your system. Your system will power on to the Petitboot bootloader menu. This process takes about 1 - 2 minutes to complete. Do not walk away from your system! When Petitboot loads, your monitor will become active and you will need to push any key in order to interrupt the boot process.
  2. At the Petitboot bootloader main menu, select Exit to Shell.

  3. Run ipmitool lan print 1. If this command returns an IP address, verify that is correct and continue. To set a static IP address, follow these steps:

    1. Set the mode to static by running this command: ipmitool lan set 1 ipsrc static
    2. Set your IP address by running this command: ipmitool lan set 1 ipaddr ip_address where ip_address is the static IP address that you are assigning to this system.
    3. Set your netmask by running this command: ipmitool lan set 1 netmask netmask_address where netmask_address is the netmask for the system.
    4. Set your gateway server by running this command: ipmitool lan set 1 defgw ipaddr gateway_server where gateway_server is the gateway for this system.

    5. Confirm the IP address by running the command ipmitool lan print 1 again.

      This network interface is not active until after you perform the following steps:

  4. To reset your firmware, run the following command: ipmitool mc reset cold.

    This command must complete before continuing the process; however, it does not return any information. To verify that this command has completed, ping your system BMC address (the same IP address used in your IPMItool command). When the ping returns successfully, continue to the next step.

    1. If your ping does not return successfully within a reasonable amount of time (2 - 3 minutes), try these additional steps:

      1. Power your system off with this command: ipmitool power off.
      2. Unplug the power cords from the back of the system. Wait 30 seconds and then apply power to boot BMC.

10.1.5. Powering on your server with IPMI

Intelligent Platform Management Interface (IPMI) is the default console to use when connecting to the OPAL firmware.

Use the default values for IPMI:

  • Default user: ADMIN
  • Default password: admin
Note

After your system powers on, the Petitboot interface loads. If you do not interrupt the boot process by pressing any key within 10 seconds, Petitboot automatically boots the first option. To power on your server from a PC or notebook that is running Linux, follow these steps:

  1. Open a terminal program on your PC or notebook.

  2. To power on your server, run the following command: 

    ipmitool -I lanplus -H server_ip_address -U ipmi_user -P ipmi_password chassis power on

    where server_ip_ipaddress is the IP address of the Power system and ipmi_password is the password set up for IPMI.

    Note

    If your system is already powered on, continue to activate your IPMI console.

  3. Activate your IPMI console by running this command 

    ipmitool -I lanplus -H server_ip_address -U ipmi_user -P ipmi_password sol activate
Note

Use your keyboard up arrow to display the previous ipmitool command. You can edit previous commands to avoid typing the entire command again. If you need to power off or reboot your system, deactivate the console by running this command: 

ipmitool -I lanplus -H server_ip_address -U user-name -P ipmi_password sol deactivate

To reboot the system, run this command: 

ipmitool -I lanplus -H server_ip_address -U user-name -P ipmi_password chassis power reset

10.1.6. Choose your installation boot method on IBM LC servers

You can either boot the Red Hat Enterprise Linux installation from a USB device or through virtual media.

To boot the installation from a USB device, see Configuring Petitboot for installation with USB device

To boot the installation through virtual media, see Access BMC Advanced System Management interface to configure virtual media.

10.1.6.1. Configuring Petitboot for installation with USB device

After the system powers on, the Petitboot bootloader scans local boot devices and network interfaces to find boot options that are available to the system. For information about creating a bootable USB device, see Creating a bootable DVD or CD.

Use one of the following USB devices:

  • USB attached DVD player with a single USB cable to stay under 1.0 Amps
  • 8 GB 2.0 USB flash drive

Procedure

Follow these steps to configure Petitboot:

  1. Insert your bootable USB device into the front USB port. Petitboot displays the following option: 

    [USB: sdb1 / 2015-10-30-11-05-03-00]

10.3.6. Powering on your L server with IPMI

Intelligent Platform Management Interface (IPMI) is the default console to use when you configure your Power system. If you are using a Linux notebook or PC, use the ipmitool utility. If you are using a Windows notebook or PC, use the ipmiutil utility.

As the system powers up, you might notice the following actions:

  • System reference codes appear on the control panel display while the system is being started.
  • The system cooling fans are activated after approximately 30 seconds and accelerate to operating speed.
  • The power LED on the control panel stops flashing and remains on, indicating that system power is on.

After your system powers on, the Petitboot interface loads. If you do not interrupt the boot process by pressing any key within 10 seconds, Petitboot automatically boots the first option.

    Where ipaddress is the IP address of the Power system and ipmi_password is the password set up for IPMI.

  3. Immediately activate your IPMI console by running this command: 

    ipmitool -I lanplus -H fsp_ip_address -P ipmi_password sol activate
    Tip

    Use your keyboard up arrow to display the previous ipmitool command. You can edit previous commands to avoid typing the entire command again.

Note

If you need to restart your system, follow these steps:

  1. Deactivate the console by running this command: 

    ipmitool -I lanplus -H fsp_ip_address -P ipmi_password sol deactivate

  2. Power your system off with this command: 

     ipmitool -I lanplus -H fsp_ip_address -P ipmi_password power off

  3. Power your system on with this command: 

     ipmitool -I lanplus -H fsp_ip_address -P ipmi_password power on
Note

If you have not already done so, insert your DVD into the DVD drive or confirm the installer image in your network

10.3.6.2. Powering on your system from a notebook or PC running Windows

10.3.7. Configuring Petitboot and installing Red Hat Enterprise Linux

After the system powers on, the Petitboot boot loader scans local boot devices and network interfaces to find boot options that are available to the system. If you do not have network connectivity or the installation DVD in the disk drive, no boot options are listed.

Important

As shown in the following example, for Power Systems servers, Petitboot lists any identified encrypted devices in the boot menu, even if there are no boot options associated with the devices. The encrypted devices can be ignored when selecting the boot device. In this example, disk, system, and device indicate your specific disk, system, and device information. 

Petitboot (v1.11)
 [Disk: sda2 / disk ]
    Red Hat Enterprise Linux (system) 8.x
*[Encrypted Device: rhel device / device

  System information
  System configuration
  System status log
  Language
