I am running Server 2012 Datacenter. I have a VDI pool with 10 desktops. For the sake of simplicity, we'll say they are named Desktop-0 through Desktop-9. Whenever I need to modify the template, I use the "Recreate All Virtual Desktops" task. Usually, this works fine, but I need to know what to do when it gets interrupted. Because, for instance, Windows Server Backup will interrupt it, and certain other tasks can interrupt it as well. Today's attempt to do the recreate left two desktops missed because users were logged into them and they didn't get logged out before something else caused an interruption. I can still view the task status details, but they go away every time Windows Server Backup runs (I am using Windows Server Backup temporarily until I can get System Center configured). The task details currently look like this:
8/10 virtual desktops were successfully recreated.
2 virtual desktops failed.
Desktop-0 Complete
Desktop-1 Complete
Desktop-2 Complete
Desktop-3 Complete
Desktop-4 Failed: Failed to lock VM
Desktop-5 Complete
Desktop-6 Complete
Desktop-7 Failed: The operation has been cancelled.
Desktop-8 Complete
Desktop-9 Complete
Is there anything I can do to get those desktops to recreate? I didn't have any luck trying to get any of the PowerShell commands I found to do individual desktops this way, and the GUI doesn't appear to have a way to do that. I haven't tried running the "Recreate All Virtual Desktops" task again because I won't be able to have all users log out before it is interrupted at this time. While it wouldn't be ideal, should that work? Additionally, in the meantime, will the two failed desktops continue to function on the old version of the template?
