invoke-command and get-itemproperty

Hello,

foreach($inst in $list_inst) {
	$inst_name = $inst.name.replace("MSSQL$","")

	$comp_name1 = (get-itemproperty -path "HKLM:\SOFTWARE\Microsoft\Microsoft SQL Server\Instance Names\SQL").$inst_name
	$key_name = "HKLM:\SOFTWARE\Microsoft\Microsoft SQL Server\"+$comp_name1 + "\Cluster"
	$key_prop = get-itemproperty -path $key_name -ErrorAction silentlycontinue 
	if($key_prop -eq $null) {
		$ser_name = (Get-WmiObject Win32_Computersystem).Name
	}
	else {
		$ser_name = $key_prop.ClusterName
	}
}

Open in new window

     I have to modify these following commands for access remote registry because this error is returned :
      Get-ItemProperty : Cannot find path 'HKLM:\SOFTWARE\Microsoft\Microsoft SQL Ser
      ver\Instance Names\SQL' because it does not exist.

      $comp_name1 = (Invoke-Command -ComputerName $mach_name -ScriptBlock { (get-itemproperty -path "HKLM:\SOFTWARE\Microsoft\Microsoft SQL Server\Instance Names\SQL").$inst_name})
      $key_name = "HKLM:\SOFTWARE\Microsoft\Microsoft SQL Server\"+$comp_name1 + "\Cluster"
      $key_prop = Invoke-Command -ComputerName $mach_name -ScriptBlock {$key_prop = (get-itemproperty -path $key_name)-ErrorAction silentlycontinue }


      But $comp_name1 is null because the invoke-command is not correct and $key_prop failed with the following error :
      Cannot bind argument to parameter 'Path' because it is null.
          + CategoryInfo          : InvalidData: (:) [Get-ItemProperty], ParameterBindingValidationException
          + FullyQualifiedErrorId : ParameterArgumentValidationErrorNullNotAllowed,Microsoft.PowerShell.Commands.GetItemPropertyCommand



How can I resolve this problem ?

Thanks

Regards

Bibi

Try to pass variable as a argument to ScriptBlock..
$comp_name1 = (Invoke-Command -ComputerName $mach_name -ScriptBlock { (get-itemproperty -path "HKLM:\SOFTWARE\Microsoft\Microsoft SQL Server\Instance Names\SQL").$args[0]}) -Args $inst_name

Hello,

Thanks I have tested :
You must provide a value expression on the right-hand side of the '-' operator.
At line:1 char:175
+ $comp_name1 = (Invoke-Command -ComputerName $mach_name -ScriptBlock { (get-itemproperty -path "HKLM:\SOFTWARE\Microso
ft\Microsoft SQL Server\Instance Names\SQL").$args[0]}) - <<<< Args $inst_name
    + CategoryInfo          : ParserError: (:) [], ParentContainsErrorRecordException
    + FullyQualifiedErrorId : ExpectedValueExpression

Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

Also Also did you modify the following line with argument?
$key_prop = Invoke-Command -ComputerName $mach_name -ScriptBlock {$key_prop = (get-itemproperty -path $key_name)-ErrorAction silentlycontinue }

If you want to add -ErrorAction silentlycontinue for get-itemproperty, then it should be inside the bracket..
$key_prop = Invoke-Command -ComputerName $mach_name -ScriptBlock {$key_prop = (get-itemproperty -path $key_name -ErrorAction silentlycontinue) }

Open in new window

Else if it is for Invoke-Command the it should be outside the script block..
$key_prop = Invoke-Command -ComputerName $mach_name -ScriptBlock {$key_prop = (get-itemproperty -path $key_name) } -ErrorAction silentlycontinue

Open in new window


Also pass the $key_name as a argument to ScriptBlock..
$key_prop = Invoke-Command -ComputerName $mach_name -ScriptBlock {get-itemproperty -path $args[0] } -Args $key_name -ErrorAction silentlycontinue

The final result is:
      $comp_name1 = (Invoke-Command -ComputerName $mach_name -ScriptBlock { (get-itemproperty -path "HKLM:\SOFTWARE\Microsoft\Microsoft SQL Server\Instance Names\SQL").$args} -Args $inst_name)
      $key_name = "HKLM:\SOFTWARE\Microsoft\Microsoft SQL Server\"+$comp_name1 + "\Cluster"
      $key_prop = Invoke-Command -ComputerName $mach_name -ScriptBlock {get-itemproperty -path $args[0] } -Args $key_name -ErrorAction silentlycontinue
