Base image partition test
The Diagnostics Tool checks if the partitions are created correctly and the sectors are
undamaged.
Structure of the partitions:
● BIOS Grub (/dev/sda1)
● EFI partition (/dev/sda2)
● Data of the Software Controller (/dev/sda3)
● Memory area of the Software Controller (/dev/sda4)
● Reserved for the Linux operating system (/dev/sda5)
File version consistency test
The Diagnostics Tool checks if the data of the Software Controller on the third partition
(/dev/sda3) is consistent.
GPT (GUID Partition Table) test
The Diagnostics Tool checks the headers of each partition and whether each partition
property on the base image is consistent.
SWCPU memory area test
The Diagnostics Tool checks the hardware-specific configuration of the Software Controller
on the fourth partition (/dev/sda4).
Kernel architecture test
The Diagnostics Tool checks the architecture of the installed operating system.
VNIC (Runtime communication interface) connectivity test
The Diagnostics Tool checks the connection of the runtime communication interface.
