Hot-Add/Virtual Appliance Failures

Challenge

All hot-add/Virtual Appliance Jobs fail with the following:

 

BackupDiskTrad failed
Client error: Failed to open VDDK disk [[My_Datastore] VM_Name/Disk1.vmdk] ( is read-only mode - [true] )
Logon attempt with parameters [VC/ESX: [vcenter];Port: 443;Login: [domain\veeam_user];VMX Spec: [moref=vm-5555];Snapshot mor: [snapshot-55];Transports: [hotadd]] failed because of the following errors:

Server error: End of file


 

Also, the Veeam box may have been moved or cloned recently, causing the UUID of the Veeam box to change.

Cause

After moving/cloning or copying the Veeam box, the UUID on the VMware side and the UUID that Microsoft gives a machine will go out of sync. Also the host we are trying to do hot-add/virtual appliance mode with cannot find the UUID provided, as it has changed and is no longer valid.

Solution

To resolve, run the following PowerShell script on the Veeam box:
 

$uuid = (Get-WmiObject Win32_ComputerSystemProduct).UUID
$array_uuid = @()
$array_uuid += $uuid.split("-")
$tempArray = @()
for($j = 0; $j -lt 5;$j++)
{
    $tempArray = @()
    for($i=0;$i -lt $array_uuid[$j].length;$i+=2)   
    {
        $tempArray += $array_uuid[$j][$i] + $array_uuid[$j][$i+1]
    }
    if($j -lt 3){ [array]::Reverse($tempArray)}
   
    $array_uuid[$j] = $tempArray
}
$array_uuid[3][0] = $array_uuid[3][0].Insert(0, "-")
$myUuid = ($array_uuid | Out-String).Replace("`n"," ").Replace(" -","-")
if((Get-WmiObject -Class Win32_ComputerSystem).SystemType -match "(x86)")
    {Set-ItemProperty "HKLM:\software\VMware, Inc.\VMware Virtual Disk Development Kit\volatile\" -Name "UUIDHost" -value $myUuid}
else
    {Set-ItemProperty "HKLM:\software\Wow6432Node\VMware, Inc.\volatile\" -Name "UUIDHost" -value $myUuid}
