When I run this below piece of code using task scheduler.I get an output where the last server mentioned repeats random number of times.(sometimes it repeats twice or thrice or 5 times or appears normally,once as it is supposed to.
When I schedule it as a task it does not run , but when I manually run it gives me an output as described above as an html email table but with the last server(in the text file) repeating randomly.
In task scheduler: --> Actions
Program script:powershell.exe
-ExecutionPolicy Bypass -Command "X:\SpaceDetails.ps1"
And if I run the below powershell code as part of a SQL job it throws the following error.
A job step received an error at line 150 in a PowerShell script. The corresponding line is ' Write-Host $item.DeviceID $item.VolumeName $item.FreeSpace $item.Size'. Correct the script and reschedule the job. The error information returned by PowerShell is: 'Cannot invoke this function because the current host does not implement it. '. Process Exit Code -1. The step failed.
How can I fix the above 3 scenarios.
1.make the task scheduler run as scheduled.
2.Upon manual run give a proper output without the last server repeating randomly.
3.Fix the issue as part of the SQL job and get the code to run as part of the SQL job.
Thanks
