Attempting to “Get Device Image” from within Dell Wyse Device Manager Version 5.0 errors with: “can’t access tty; job control turned off”

Problem

You attempt to use the Get Device Image feature (non PXE) from within Dell Wyse Device Manager Version 5.0 to pull an image off of a Wyse Thin Client:

The WDM Server is able to restart the Thin Client and begin the process of uploading the server but you notice that the progress never increases from 0% and eventually errors out with:

BusyBox v1.00 (2007.02.08-11:26+0000) Built-in shell (ash)

Enter ‘help’ for a list of built-in commands.

/bin/sh: can’t access tty; job control turned off

/bin #

Nothing happens and you are forced to restart the thin client.

Solution

The Wyse thin client I was working with was an older Z90S7 model and apparently had an older Boot Agent that needed to be updated so from within the Wyse Device Manager console, I navigated to Package Manager –> Other Packages then dragged and dropped the BootAgent item to the Device Manager node:

Continued through the wizard and selected the thin client to be updated:

I was then able to successfully pull the image from the Wyse thin client once the boot agent was updated:

  1. That's great, but how did you get the updated Boot Agent on the device when it was sitting at the bin# prompt? If you run the updated from WDM, it does nothing on the thin client, even if you reboot the thin client?

    Thanks!
