Running Multiple reacl.exe Instances in Parallel for NAS Processing

If you’re managing large-scale file share migrations or ACL updates using the command line tool reacl.exe in On Demand AD Migration, you’ve probably encountered difficulties trying to configure them to run all at once from a jump host. I recently faced this challenge and built a PowerShell script to streamline the process. Here’s how you can do it too.

Prerequisites

Before you dive in, ensure the following:

• Install the Desktop Agent on the server where you’ll run the script.

• Update your system Path to include the location of reacl.exe.

• Run a single reacl job manually from the console under FileShares to generate the necessary password and config files.

Preparing Your Config Files

Once you’ve run a job manually:

1. Grab the generated Reacl-Config.json file. You can find it at:
   • C:\Program Files (x86)\Quest\On Demand Migration Active Directory Agent
2. Create a template version of this file. Replace the path with a placeholder like XXXX, so you can dynamically update it later.
3. Build a ShareList.txt file containing all the shares you want to process.

$jFile = "C:\quest\Reacl-config.json"
$shareFile = "C:\quest\ShareList.txt"

$shareList = Get-Content -Path $shareFile

Foreach ($share in $shareList)
{
$splitShare = $share.split("\\")
$configName = $splitShare[$splitShare.count-1]

$jsonContent = Get-Content -Path $jFile | ConvertFrom-Json
$jsonContent.remoteFolders[0].path = $jsonContent.remoteFolders.path.Replace("XXXX",$share)
$outJson = "c:\quest\reacl-config-" + $configName + ".json"
$jsonContent | ConvertTo-Json -Depth 10 | Set-Content $outJson

$cmdFile = 'c:\quest\reacl' + $configName + '.cmd'
$logFile = '"c:\Quest\' + $configName + '.log"'
$cmdLine = 'reacl.exe /CONFIG:' + '"' + $outJson + '"' + ' > ' + $logFile
$cmdLine | set-content $cmdFile
Start-Process -FilePath "cmd.exe" -ArgumentList "/k", $cmdFile
#pause
}
