nvme-CT2000P3PSSD8_2226E6439812-part1
nvme-CT2000P3PSSD8_2226E6439812-part2

If the devices you want to write have the common name of "nvme-CT2000P3PSSD8", then enter it in the prompt below:
What is the common string that can most describe this kind of device?
Enter here: nvme-CT2000P3PSSD8
Then it will proceed with the devices with the given common string in the device name. Next time if you know the common string, it can be directly given in the command:
./bulk_flash_image.sh image_to_flash.img -s nvme-CT2000P3PSSD8If you want to suppress the prompt to confirm to continue, -f option can be added:
./bulk_flash_image.sh image_to_flash.img -s nvme-CT2000P3PSSD8 -f
