The following steps are required to generate a backup of the OS for the Ardia Server that also contain the necessary Ardia configuration files and Kubernetes engine metadata.

NOTE

The OS backup requires the Ardia Server to be power cycled. The backup may occupy up to 500GB on /k3s-storage/hdd filesystem.

Procedure

  1. Reboot the server (this can be done by executing the following command in Terminal: sudo reboot), or start the server if already shutdown.
  2. If SecureBoot is enabled, turn it off in BIOS by selecting System Setup Main Menu > System BIOS > System Security.
  3. Alternatively, you can disable SecureBoot in iDRAC by selecting Configuration > BIOS settings > System Security.

  4. NOTE

    By default, Ardia 1.0 has SecureBoot set in BIOS to false.

  5. To apply the new setting, a further reboot of the server is required.
  7. Choose one of the following ways to boot the server from the Ardia Server Rescue Linux ISO USB:
  8. From a prepared USB flash drive
  9. From iDRAC Virtual Media that creates a virtual drive the server can boot from

From a prepared USB flash drive

Procedure

  1. Insert the USB flash drive into the server.
  2. Reboot the server.
  3. While it is rebooting, press F11.
  5. Select One-shot UEFI Boot Menu.
  7. Select Disk connected to back USB 1: <USB Drive Name>.
  9. Continue with this step.

From iDRAC Virtual Media that creates a virtual drive the server can boot from

Procedure

  1. To use iDRAC Virtual Media, open the iDRAC IP address in a browser and log in to the iDRAC console.
  2. In Ardia 1.0 the default built-in account is root.
  3. In Ardia 1.1, the default built-in account is renamed from root to oobm-admin.
  5. After a successful login, a dashboard is displayed.
  6. Perform the boot of virtual media of Ardia Server Rescue Linux by following next steps:
  7. Open the iDRAC Virtual Console.
  8. Insert the USB drive that has the ISO file copied on to it.
  10. Select Virtual Media from the top menu.
  11. In the Virtual Media window, select Connect Virtual Media.
    - Under section Map CD/DVD, select Choose File and locate the Ardia Server Rescue Linux ISO file.
  12. Select Map Device.
  14. After successfully mounting of the ISO image, a dialog box confirming the success appears.
  15. Select OK to confirm the success.
  16. In the iDRAC Virtual Console, under Boot Controls, select Virtual CD/DVD/ISO.
  18. In the iDRAC Virtual Console, to restart the server, select Power.
  19. In the Power Controls dialog box, select Reset System (warm boot).
  21. Select Yes to confirm the power action.
  23. Continue with this step.

Continued procedure for creating a Ardia Server Ubuntu Linux OS backup

Procedure

  1. Press the Enter key.
  2. The server will boot into Ardia Server Rescue Linux with Ardia Platform Configurator tool.
  3. The Firefox web browser automatically loads with the Ardia Platform Configurator (APC) tool.
  4. Log in to APC using your admin account.
  7. In APC, select OS backup.
  8. Select Generate new backup and confirm to generate a new backup.
  10. If a backup already exists, it is overwritten. The tool maintains only the latest backup and stores it in the Ardia Server Hard Drives. These are accessible at /k3s-storage/hdd, in the file system.
  12. Select OK.
  14. The backup creation can take up to 4 hours.
  15. Once the backup is created, select Download.
  16. The file is automatically stored in the /home/rescue-admin/Downloads folder and /k3s-storage/hdd on the Ardia Server file system.
  18. Select the Checksum file to download the xxHash checksum.
  19. In order to make a copy of the files to be stored outside of the Ardia server, attach a USB flash drive to the server and copy the files located at /k3s-storage/hdd. Ensure to eject the USB media safely before unplugging it from the server.

  20. NOTE

    APC maintains one copy of the backup only, if you run the backup multiple times, only the latest backup will be stored on the server.

  21. Once the backup is complete, safely remove the Ardia Rescue USB flash drive from the OS and unplug the drive from server.
  22. Thermo Fisher Scientific recommends attaching the USB drive with the Ardia backup to your computer and copy files to your computer’s local disk.
  23. Power off the server.
  24. Double check that there is no USB drive attached to the server and start the server.
  27. Power on the server.
  28. The system state capture is complete, you can now continue to the Ardia Server upgrade procedure.
