PowerShell Scripting Dell Command Update
We have a lot a Dell machines and I wanted to be able to utilize the Dell Command Update utility to automatically update Dell software and firmware through a Scripting Plan. I ran into a LOT of issues and it seems like many are the way PowerShell is executed by the Aconis agent vs running PowerShell interactively.
I'm not a developer but I got this thing working. You will notice that there are some repetitive sections of the script and many places that appear to be able to optimized by functions and so forth. However, when I attempted to write the script in a more optimized manner, it would always error out in Acronis - even though it worked fine just running the script in a PowerShell session locally on a machine.
The script will check to see if the machine is a Dell or not before continuing to check for any incompatible software like the universal version of DCU or any version of Dell Update. It will then uninstall those, download a specific version of DCU using a user agent of Chrome instead of PowerShell so it doesn't get blocked by the web server, install DCU, then run DCU via command line, and reboot if needed. You can check local logs on the device in the C:\source\DCU directory or download the script stdout from the Activity in the Acronis console.
I am attaching the script as a text file to the post. I hope this will be helpful and that it will be improved upon.
I don't need support on this. This was just me posting to help others potentially. I will say that Support was completely unable or unwilling to troubleshoot scripting. They basically just said, "The problem is your script." While "technically" correct that the script needed to change to run, the reason is BECAUSE of the constraints imposed by Acronis and the way the Acronis agent executes scripts.
If PowerShell scripts have to be written a special way to execute through Acronis when they work just fine without Acronis, then Acronis ought to actually publish documentation on how to do it correctly instead of just making people go figure it out.
