Lenovo P620

@terrigan Well that’s very interesting in that it recieved a dhcp answer and then it tried to download default.ipxe. I assume the redacted text is really the IP address of the FOG server?

If at this error menu press the s key to drop to the ipxe shell. Since we are seeing network 0 getting an address the question is, what is it.

From the iPXE shell key in the following
show net0/ip
It should respond with the IP address of the target computer. Is that IP address expected?

Key in:
show filename
to show the boot file name, should be snp.efi

Key in:
ping <redacted_fog_ip>
Does it return a response?

if you then key in
chain tftp://<redacted_ip_address>/default.ipxe does it boot?

[terrigan]

@george1421 First command nets a valid IP address on our network. Show filename shows snp.efi. However, when i get to the point where I need to ping, there is no response. I cannot ping the fog server, or gateway or anything really.

This is interesting and maddening at the same time. Is the fog server on the same subnet as the lenovo? I can’t quite explain why it gets an IP address but can not ping the fog server. Something is missing here.

@george1421 Yes, i can boot a non p620 from the same rj45, get a different address on the network and Fog works beautifully.

I’m not sure I saw an answer to this. Is the pxe booting computer on the same subnet as the FOG server?

[terrigan]

@terrigan No our fog server is on our server subnet, however all of our vlans can talk to it. This works properly with every computer except this P620.

[george1421]

@terrigan OK now we have something else to check. Once again I’ll say that something strange is going on with this P620.

Now that we know the fog server is on a different subnet, lets run a few more commands.

1. Do you have a device on the target computer’s subnet you can ping?
2. Lets once again go into the shell console of iPXE. Lets run the following command
   dhcp && route
   That should display the message about getting dhcp address again and then it will print the route and gateway info it gets from dhcp. Is the gateway info valid. If your network allows it can you ping the gateway address?

[terrigan]

@terrigan All the information from dhcp && route is valid, including gateway. iPXE will not ping the valid gateway, Connection Timed Out.

I found this, https://github.com/ipxe/ipxe/issues/294#issuecomment-1483940557 regarding the Marvell Aqtion card, is the driver not built in to the current iPXE release? Apparently it seems to have been left out. https://github.com/ipxe/ipxe/issues/294#issuecomment-1515243514.

I have since given up. I opened a ticket with Lenovo and got the Windows 10 recovery download for this machine and will have to manually strip it of junk.

@terrigan You could try booting this particular model via USB key to get around the issue.
