About Workflow

Question

Hi there,

I'm new here, and recently I was scratch my head with something:

I'm wondering if a workflow can continue to run if the computer is rebooted. For example:
Workflow {
Do job 1
reboot
Do job 2
reboot
Do job 3
reboot
Do job 4
reboot
Do job 5
Reboot
done.
}

My question is, after each reboot, can the next job start or it will start from job 1? The workflow will be in a powershell script file which will be schedule to run every time the computer reboots.

Please help.
Thanks

Hi，

The -Wait parameter suppresses the PowerShell prompt and it's only for remote computers. You can try start-sleep

workflow test {  
Add-Content -Path "c:\bbc\bbc.txt" -Value "Task 01"  
Restart-Computer -force  
Start-Sleep -Seconds 60  
Add-Content -Path "c:\bbc\bbc.txt" -Value "Task 02"  
Restart-Computer -force  
Start-Sleep -Seconds 60  
Add-Content -Path "c:\bbc\bbc.txt" -Value "Task 03"  
Restart-Computer -force   
Start-Sleep -Seconds 60  
Add-Content -Path "c:\bbc\bbc.txt" -Value "Task 04"  
}  
test

Thank you all for your help, I'm testing this script on a local computer:
workflow test {
Add-Content -Path "c:\bbc\bbc.txt" -Value "Task 01"
Restart-Computer -force -Wait
Add-Content -Path "c:\bbc\bbc.txt" -Value "Task 02"
Restart-Computer -force -Wait
Add-Content -Path "c:\bbc\bbc.txt" -Value "Task 03"
Restart-Computer -force -Wait
Add-Content -Path "c:\bbc\bbc.txt" -Value "Task 04"
}
test

I'm following these steps:

1. on my computer, run this script, it will reboot
2. after 1st reboot, I login and see Task1 and Task 02 in bbc.txt
3. I'm expecting it reboots again, but it won't. When I check the job status by typing Get-Job, it shows suspended
4. I have to manually resume the job, then it reboots again. When I login back, the file shows Task01, Task02, Task03, Task04, but the 3rd reboot didn't happen.

Is there anything I did wrong?
Thanks !!

The answer is yes, but you'd have to add checkpoints to the workflow at the point you'd like it to resume. In the case of a reboot, you'd use the Restart-Computer with the -Wait parameter. I believe you'd also have to create a scheduled task that runs "AtStartup" that would resume the workflow if you don't want to do that restart manually.

Hi,

It will start from job 1 after a reboot. To start from the next job, you can use the Restart-Computer cmdlet to reboot. It will create a job of type PSWorkflowJob and you can resume the workflow using the Resume-Job cmdlet.
