the pc running the console will broadcast continuously a signal on the LAN when the action load standalone kernel is started and wait for the nas to respond. The broadcat signal is send to all devices connected to the LAN.
The bootloader of the 5big2 (connected with a lan cable to the LAN) will activate the network card and listen for a few seconds if this special signal is there which included an IP address to set. If yes it switches to netconsole mode sets the ip addres and also starts a tftp client address and sends a signal to device that has send the broadcast, that is detected by the fvdw-sl console and this t then makes a connection to the nas using netcat and starts a tftp server, then it instructs the bootloader (u-boot) to upload a the standalone kernel using the tftp client in the nas and tftp server running on the PC. After that the console instructs the bootloader to load and start the kernel.
To make it work your VM must have access to your network card and traffic must not be blocked by a firewall, alsonot for the tftp server started by the the console and later the telnet client.
Furthermore don't use wireless connections, used wired for PC to lan
Easy, piece of cake :-D
I see that for a the 5big Lacie v2 that only the 1st disk should be installed. However, what is not clear is what disk should be used. What I mean is that I'm guessing it shouldn't be any of the disks that were originally in the NAS, which contained the RAID 5 array and should be some other old unneeded or brand new disk. Is that right?
No, this is when you want to install the fvdw-sl firmware.
If you want to investigate the raid array then keep all disk in and just load the the standalone kernel
