Hi
I use App Volumes in our VDI environment, and if you aren't aware can use vmdk files to store the application. These are not associated with any VM until they are needed. Currently I have a powercli script download the file from vcenter and the upload it to the other one. This was because in 5.5 it wasn't possible to use the ps-drives between vcenters. I was going to look into this again and wanted to see if there was a better option. Here is how I'm doing it now, which uses a csv file to make sure the files get where they need to, but is basically a recursive copy of the entire datastore.
function Recusive2VcenterDSCopy
{
param([string]$ItemPath,
[string]$TargetPath)
$datastoreitems = Get-ChildItem -path $ItemPath
foreach ($dsItem in $datastoreitems )
{
if($dsItem.ItemType -eq "Folder")
{
$foldername=$ItemPath+"\"+$dsItem.Name
$targetfoldername=$TargetPath+"\"+$dsItem.Name
$localname="C:\Scripts\appvolsync\"+$dsItem.Name
Write-Host "Looking in " $foldername " for things to copy"
if(!(Test-Path $TargetPath))
{
try{
Copy-DatastoreItem -Item $foldername -Destination $localname -ErrorAction Stop
}catch{
switch -wildcard ($error[0].Exception.ToString().ToLower())
{
"*already exists*" {Write-Output "File Already Exists"}
default {
sendMail($error[0].Exception.ToString().ToLower())
}
}
}
try{
Copy-DatastoreItem -Item $localname -Destination $TargetPath -ErrorAction Stop
}catch{
switch -wildcard ($error[0].Exception.ToString().ToLower())
{
"*already exists*" {Write-Output "File Already Exists"}
default {
sendMail($error[0].Exception.ToString().ToLower())
}
}
}
Remove-Item $localname -recurse
}
Recusive2VcenterDSCopy -ItemPath $foldername -TargetPath $targetfoldername
}else{
$foldername=$ItemPath+"\"+$dsItem.Name
$targetfoldername=$TargetPath+"\"+$dsItem.Name
$localname="C:\Scripts\appvolsync\"+$dsItem.Name
$remoteFile=$TargetPath+"\"+$dsItem.Name
if(!(Test-Path $remoteFile))
{
Write-Host $remoteFile "Does not Exist"
try{
Copy-DatastoreItem -Item $foldername -Destination C:\Scripts\appvolsync\ -ErrorAction Stop
}catch{
switch -wildcard ($error[0].Exception.ToString().ToLower())
{
"*already exists*" {Write-Output "File Already Exists"}
default {
sendMail($error[0].Exception.ToString().ToLower())
}
}
}
try{
Copy-DatastoreItem -Item $localname -Destination $TargetPath -ErrorAction Stop
}catch{
switch -wildcard ($error[0].Exception.ToString().ToLower())
{
"*already exists*" {Write-Output "File Already Exists"}
default {
sendMail($error[0].Exception.ToString().ToLower())
}
}
}
Remove-Item $localname -recurse
}
}
}
