Hi,

I recently setup a HPC cluster using HPC 2016.

Setup:
Few details about the cluster are below:

  • Windows Server 2016
  • Single Head node configuration
  • Network Topology 5
  • 48 Compute Nodes added to the cluster
  • 5 databases setup in a remote DB server

Context:
Recently started to install the Update 1 for the HPC 2016 version.
Completed the installation on all compute nodes as mentioned in the official documentation:
https://learn.microsoft.com/en-us/powershell/high-performance-computing/migration-to-hpc-pack-2016?view=hpc16-ps

Issue:
According to the documentation, head node update is supposed to be completed at the end.

  • Ran the first set of commands to take the backup
  • While running the second command, console showed error that it was unable to remove 'Microsoft Service Fabric'
  • After this step execution has stopped after uninstalling the HPC Pack 2016 RTM Excel, Server, Client
  • I tried to manually delete the above said 'Fabric' folder, it didn't work

I am attaching the console screenshots.
Can someone please point out what I am missing here?

    Hey @Sumarigo-MSFT ,
    Thanks for your response, I raised an internal ticket and got this resolved. Team provided me another script which resolved the issue.

    Resolution for this involved rebooting the machine and then running the script that Microsoft team had provided (MigrateSingleHN.ps1)

    Main change in the script was removing the code blocks where HPC RTM was being un-installed(as in my case that had already taken place and flow was getting blocked at that point).

    Following code blocks were removed from the default file that comes with Update 3

    Lines 89 - 106, 129-135 and the signature block at the end.
