@george1421 so I did your method by using ssh to get into the fos of the target computer during the imaging process and I found a command that worked I typed storage=fogstorage01.gmh.org/images and got a successful completion command that youll see here in the screenshot

so, seeing this I think I can implement this parameter in a postinit script to run by manually mapping subnets or using a helper function within the script to get the host ip address then match it to the proper storage node by implementing something like if the host ip matches subnet 10.130.208.0/24 storage=fogstorage02.gmh.org/images or if its 10.130.192.0/24 storage=fogstorage02.gmh.org/images and see if it completes successfully. I am going to attempt this then I will report back the results.

@george1421 passing the command storage=fogstorage01.gmh.org/images is confirmed successful by the screenshot below

so, knowing this I think passing this in a postinitscript will actually work, I am going to attempt this on the next boot to test it out and I will post the script I created to have this work if it is successful

@JamiesonCA092 typo in this column the command was storage=fogstorage01.gmh.org/images

@george1421 @Wayne-Workman but thank you guys I think with what you provided me so far will put me on the right track to my solution.

@george1421 @Wayne-Workman I was thinking towards the postinit script as well before, but I had the same concerns that @Wayne-Workman mentioned about the changes persisting after the script was ran as well. I’m about to continue working on this now, I was messing around in the ipxe menu items and was able to have the server pass the image I want to use automatically on a new menu item I created like so, in my mind if you are able to pass this logic to set the image you should be able to pass the same logic if I find the right parameters to set the storage node as well since that logic can be passed with the registered host using the location or subnet plugin:

login
set imageID 1
params
param mac0 ${net0/mac}
param arch ${arch}
param imageID ${imageID}
param qihost 1
param username ${username}
param password ${password}
param sysuuid ${uuid}
isset ${net1/mac} && param mac1 ${net1/mac} || goto bootme
isset ${net2/mac} && param mac2 ${net2/mac} || goto bootme

so, once I saw I was successfully able to pass this over and it worked I experimented with different parameters to set the storage node as well based on parameters I saw that gets passed in some of the php scripts already within fog server, I set the storage location to 4 which corresponds with one of my storage nodes identifiers in the sql database but got a kernel panic so not sure if that parameter actually worked when I did that or what. I was trying to see if I could successfully pass the parameter manually that way I could understand how to make it automated after then I could add some subnet mappings for the server to review the ip address of the host and map it accordingly to the proper node, or if this fails I was going to see if there is a way to add logic in the decision making process of the main fog server to measure the latency so that it will always choose the closest node either will work if I can make it happen. I was also looking into the location/subnet plugins that I have installed to see if there is a way to modify those to work with unregistered host or at least mimic functions they add in a similar way for unregistered host. The solution I’m looking for is deff possible just have to put the right pieces together and make it whole, once I do figure this out I will post my solution, I think there would be many others that would like to be able to utilize the same function. If anyone else comes up with some more ideas to add I am open to hear all.

I’ve been researching and inquiring online about this subject and I cannot find any useful info regarding it. So, the location and subnet plugins within fog only works with registered host to direct it to the storage node to use for the imaging task I know this and use this function with all registered host I have. But, I want to know if there is a way to implement this with non-registered host, where if I choose the deploy image option in the PXE menu the main fog server can determine the node to use within the same location/subnet of the client pc booting in to PXE based off info gathered from the pc like Ip address/subnet, I have not been successful yet at cracking this so I’m wondering if anyone else has attempted or been successful at doing this or could give me some ideas of where to tie all this together to make it possible. I want the node assignment during the imaging task to be automated without having to always register the host pc. I have a main fog server and 2 storage nodes on 2 different subnets within our facility right now I am running dnsmasq on the storage nodes to respond to PXE request within the different subnets and serve the files. It works great but it obviously will choose a random node based off the main server’s current logic after the deploy image option is selected; I want to see about implementing this to cut latency down by having the closest node (the node within the corresponding subnet of the client pc) to always be the one to handle imaging.

Not sure if this is relevant but I modified the embedded ipxescript from the original to automate the chain loading of the tftp server I want to use so I don’t have to enter it manually each time here is a copy of my script below, so this process is already automated but I want to automate the logic for the storage node tasked with the imaging and Ive experimented with trying to set parameters within the ipxe script did not work:
#!ipxe

Obtain DHCP lease
dhcp || goto dhcperror
echo Received DHCP lease, proceeding…

Test the hostname resolution by pinging it
ping -c 1 fogserver || goto pingerror
echo Hostname resolved, proceeding…

Proceed to netboot using the hostname directly
chain tftp://fogserver/default.ipxe || goto chainloadfailed

:chainloadfailed
prompt --key s --timeout 10000 Chainloading failed, hit ‘s’ for the iPXE shell; reboot in 10 seconds && shell || reboot

:dhcperror
prompt --key s --timeout 10000 DHCP failed, hit ‘s’ for the iPXE shell; reboot in 10 seconds && shell || reboot

:pingerror
prompt --key s --timeout 10000 Hostname resolution failed, hit ‘s’ for the iPXE shell; reboot in 10 seconds && shell || reboot

And below is the script I tried to use to attempt to set the location of the host booting over pxe to task the storage node with imaging task, which did not work due to the main servers decision is done after choices are made in the pxe menu so I do not think that adding params to this script is the way to go but I may be wrong:

#!ipxe

Obtain DHCP lease
dhcp || goto dhcperror
echo Received DHCP lease, proceeding…

Determine the location based on subnet
set clientip ${net0/ip}
set locationid 0 # Default location ID (if needed)
if (${clientip} =~ 10.130.192.) set locationid 1
if (${clientip} =~ 10.130.208.) set locationid 2

Perform the API call to set the location for this session
Replace <api-user> and <api-pass> with your FOG API credentials
set api_user <api-user>

set api_token “”
set user_token “”

Fetch API token
set api_url
http://<fog-server>/fog/management/index.php?sub=auth&action=login
params set=api_user=${api_user}&api_pass=${api_pass}
route http post ${api_url} params | parse api_token=${api_token},user_token=${user_token}

Set location via API call
set location_url

route http post ${location_url} Authorization: “Bearer ${api_token}”

Test the hostname resolution by pinging it
ping -c 1 fogserver || goto pingerror
