This is part 8 of my series of the most common PowerShell
errors that are made in my PowerShell classes.
I will be posting one a day to help you understand why an error occurred
and what the error’s meaning is.
Today’s error: No data returned from a remote command
Here is our starting code:
Invoke-Command -ComputerName
DC, SVR1 -ScriptBlock
{
Param
($ID, $MT)
Get-CimInstance
-ClassName Win32_Logicaldisk
|
Where {$_.DeviceID -eq $ID -and $_.MediaType -eq
$MT}
} -ArgumentList
12,"C:"
And here is the full error:
There is no error except nothing comes back.
Resolution:
Change the order of the arguments.
In this example, we are passing information from the local
device to the remote device. The problem
is in order of information being passed from the –ArgumentList to the PARAM() variables. They are being passed in the wrong
order. The first item in the –ArgumentList will be past to the first variable
in the PARAM() list. The second to the
second and so on and so forth.
I have had people argue with me that they should be able to
choose which value is saved to which variable.
Well, you do. This is an ordered
list. Order it correctly.
Invoke-Command -ComputerName
DC, SVR1 -ScriptBlock
{
Param
($ID, $MT)
Get-CimInstance
-ClassName Win32_Logicaldisk
|
Where {$_.DeviceID -eq $ID -and $_.MediaType -eq
$MT}
} -ArgumentList
"C:",12
