Function Invoke-DiskPartScript { <# .SYNOPSIS Run a DiskPart script on one or more remote systems .FUNCTIONALITY Computers .DESCRIPTION Run a DiskPart script on one or more remote systems. Results and errors sent to text files on that system, returned by this function, and filtered as specified. Command runs via cmd /c on the remote system, not PowerShell. Command invoked via Win32_Process Create method. Returns an object containing the computer, results, errors, command, and pattern. Be very, very catreful with this. DiskPart can do evil things. Use this at your own risk. .PARAMETER ComputerName Computer(s) to run command on. .PARAMETER DiskPartText Text to run as a DiskPart script .PARAMETER Pattern Optional regular expression to filter results .PARAMETER ScriptFile Temporary file to store DiskPart script on remote system. Must be relative to remote system (not a file share). Default is "C:\DiskPartScript.txt" .PARAMETER TempOutputFile Temporary file to store results on remote system. Must be relative to remote system (not a file share). Default is "C:\DiskPartOutput.txt" .PARAMETER TempErrorFile Temporary file to store redirected errors. Must be relative to remote system (not a file share). Defaults to "C:\DiskPartError.txt" .PARAMETER Raw Return only the output from the command .EXAMPLE Invoke-DiskPartScript -computername wbf, c-is-hyperv-1 -DiskPartText "list volume" # Run 'list volume' on wbf and c-is-hyperv-1. .EXAMPLE Invoke-DiskPartScript -computername wbf, c-is-hyperv-1 -DiskPartText "list disk" -pattern "offline" | select-object computer, results # Run 'list disk' on wbf and c-is-hyperv-1. Filter output to lines that match 'offline'. Only display the Computer and Results .EXAMPLE $ScriptContent = Get-Content C:\DiskPart.txt -Raw Invoke-DiskPartScript -ComputerName c-is-hyperv-1 -DiskPartText $ScriptContent # Get the content of an existing diskpart script, use it against C-IS-HYPERV-1. .LINK https://github.com/RamblingCookieMonster/PSDiskPart .LINK Invoke-DiskPartScript .LINK Get-DiskPartDisk .LINK Get-DiskPartVolume .LINK Get-DiskPartVDisk #> [OutputType('System.Management.Automation.PSObject', 'System.String')] [CmdletBinding()] param( [Parameter( ValueFromPipeline=$true, ValueFromPipelineByPropertyName=$true)] [string[]]$ComputerName = $env:COMPUTERNAME, $DiskPartText = "list disk", $Pattern, $ScriptFile = "C:\DiskPartScript.txt", $TempOutputFile = "C:\DiskPartOutput.txt", $TempErrorFile = "C:\DiskPartError.txt", [switch]$Raw ) Begin { Function Wait-Path { [cmdletbinding()] param ( [string[]]$Path, [int]$Timeout = 5, [int]$Interval = 1, [switch]$Passthru ) $StartDate = Get-Date $First = $True Do { #Only sleep if this isn't the first run if($First -eq $True) { $First = $False } else { Start-Sleep -Seconds $Interval } #Test paths and collect output [bool[]]$Tests = foreach($PathItem in $Path) { Try { if(Test-Path $PathItem -ErrorAction stop) { Write-Verbose "'$PathItem' exists" $True } else { Write-Verbose "Waiting for '$PathItem'" $False } } Catch { Write-Error "Error testing path '$PathItem': $_" $False } } # Identify whether we can see everything $Return = $Tests -notcontains $False -and $Tests -contains $True # Poor logic, but we break the Until here # Did we time out? # Error if we are not passing through if ( ((Get-Date) - $StartDate).TotalSeconds -gt $Timeout) { if( $Passthru ) { $False break } else { Throw "Timed out waiting for paths $($Path -join ", ")" } } elseif($Return) { if( $Passthru ) { $True } break } } Until( $False ) # We break out above } #Initialize command string and variables for status tracking [string]$cmd = "cmd /c diskpart /s $ScriptFile > $TempOutputFile 2> $tempErrorFile" } Process { foreach($Computer in $ComputerName){ Write-Verbose "Running '$cmd' on '$computer'" #define remote file path - computername, drive, folder path $remoteTempOutputFile = "\\{0}\{1}`${2}" -f "$computer", (split-path $TempOutputFile -qualifier).TrimEnd(":"), (Split-Path $TempOutputFile -noqualifier) $remoteTempErrorFile = "\\{0}\{1}`${2}" -f "$computer", (split-path $tempErrorFile -qualifier).TrimEnd(":"), (Split-Path $tempErrorFile -noqualifier) $remoteScriptFile = "\\{0}\{1}`${2}" -f "$computer", (split-path $ScriptFile -qualifier).TrimEnd(":"), (Split-Path $ScriptFile -noqualifier) #Attempt to delete any previous results, run command Try { Remove-Item -Path $remoteTempOutputFile, $remoteTempErrorFile -Force -ErrorAction SilentlyContinue -Confirm:$False Set-Content -Path $remoteScriptFile -Value $DiskPartText -force -ErrorAction stop } Catch { Write-Error "Error preparing $computer`n:$_" Continue } Try { Wait-Path -Path $remoteScriptFile -Timeout 10 -Interval .5 -ErrorAction stop $processID = (Invoke-WmiMethod -class Win32_process -name Create -ArgumentList $cmd -ComputerName $computer -ErrorAction Stop).processid } Catch { Write-Error "Error running '$cmd' on $computer" Continue } #wait for process to complete while ( $( try { Get-Process -Id $processid -ComputerName $computer -ErrorAction Stop } catch { if($_ -like "Cannot find a process with*") { $FALSE } else { Write-Error "Error checking for PID $ProcessId on $Computer`: $_" } } ) ) { Start-Sleep -seconds 2 } #gather results if( Wait-Path $remoteTempOutputFile -Timeout 15 -Interval .5 -Passthru ) { if($pattern) { $Results = ( Select-String -Path $remoteTempOutputFile -Pattern $Pattern | Select -ExpandProperty Line ) -join "`n" } else { if($PSVersionTable.PSVersion.Major -ge 3) { $results = Get-Content -Path $remoteTempOutputFile -Raw } else { $results = ( Get-Content -Path $remoteTempOutputFile -ReadCount 1500 ) -join "`n" } } } else { $results = "Results from '$TempOutputFile' on $computer converted to '$remoteTempOutputFile'.
