手順

1. In your ServiceNow instance, navigate to the Service Graph Connector page.
2. Select the link to the OT Discovery page.
3. The Download & Deploy OT Discovery page opens.
4. On the Download & Deploy OT Discovery page, download the Discovery Sensor for OT package.
5. Unzip the Sensor package.
   The ISO image is included in the Sensor package.
6. Create the virtual machine for the Discovery Sensor for OT.
7. We recommend that you accept the default settings when prompted during the sensor installation process.
8. Upload the ISO image to your virtualization platform.
9. Create the hardware NICs which the VM uses to communicate with the Sensor.
   注:

   The following images are examples specific to an ESXi 8.0 U2 virtual machine.

   
   
   

   注:

   For communications to work between Discovery components, two network adapters should be connected on the VM.

   
   
   

   注:

   For other VM options, ensure that EFI is selected (and not BIOS) as the Firmware and that the "Enable Secure Boot" flag is not selected.
10. Install the ISO image.
11. After installing, when alerted, remove any install media.
    The alert message is: "System needs to reboot to complete installation. Please remove all install media and once complete press any key to reboot."
12. Reboot the system.
13. After installing the ISO image, the install process starts for the Sensor installation.In your ServiceNow instance, navigate to the Service Graph Connector page.
14. Create the virtual machine for the Sensor.
15. Select the OS as Other Linux 64-bit.
16. Attach the Sensor ISO to the CD/DVD to boot the VM.
17. Create 2 hardware NICs specifically for the VM.
    注:

    For communications to work between Discovery components, two network adapters should be connected on the VM.
18. For other VM options, ensure that EFI is selected (and not BIOS) as the Firmware and that the "Enable Secure Boot" flag is not selected.
19. Assign a minimum of 8 GB RAM and 60 GB HDD for the installation.
20. Power on the VM and the install starts.
    You see this screen:
    
    
21. Select Yes to start the install.
22. Once the install is complete, select Enter to reboot the VM.
    
    
    This screen displays after the Sensor boots up.
    
    
23. On the VM page, the DMI page URL displays.
    
    
24. Use this URL to log into the DMI and register your Discovery Sensor for OT to the Discovery Console for OT.
    See Register the Discovery Sensor for OT on how to register the Sensor.

次のタスク

You can register the Sensor after you have installed the OT Discovery Console and system. Before you can register a Sensor to the Console, you must confirm that you have completed the following.

• From the Download & Deploy OT Discovery page, download the Sensor package; the Sensor ISO file is in the same package.
• Install the ISO image.
• Determine if you're using the ISO as a Virtual Machine (VM) or are installing the ISO on hardware. If you're using the ISO as a VM, you can use any of the following VMs.
  • VWware
  • Hyper-V
  • Proxmox
  • Linux KVM

    If you choose to install the ISO on hardware through BareMetal, you must use a tool to create a USB ISO installer.

• You need to open both the Console and the DMI interfaces to complete the Sensor registration.
