******

In spite of the reference to a "Linux Harvester", all of the Harvesters are running on Windows.

 

Environment

NFA 9.3.3 / 9.3.6 / 9.3.7Windows Server 2008 / 2012Windows Powershell 2.0

Cause

The 3TConverter.ps1 script attempts to determine the OS type of the Harvester machines by testing the "ResponseTimeToLive" setting of the target machine. The script may sometimes falsely think that you are running a Linux Harvester, when it is a Windows Harvester while using Powershell 2.0.

A command will fail and halt the migration.

 

Resolution

If all of the Harvesters are running on Windows machines, we can edit the "3TConverter.ps1" script to remove the OS check.

1. Edit the 3TConverter.ps1 file.
   
   
2. Replace: 

function Is-Linux-Harvester { 

Param ([String]$harvesterip) 

$TimeToLive = Test-Connection $harvesterip -Count 1 | select -exp ResponseTimeToLive 

if($TimeToLive -le 64){ 

return $true 

}else{ 

return $false 

} 

} 

 

With: 

function Is-Linux-Harvester { 

Param ([String]$harvesterip) 

return $false

}

  3. Restart the script.
