Mounting flexclone of SMVI snapshot into vcenter

[ROBHOLLOMAN]

I am working on automating our test environment refresh, which spins up a flexclone from a SMVI backup, then mounts the NFS volume into VMware vCenter.  Once mounted I will use PowerCLI to register the .vmx files and modify the VM's.  The NFS volumes are spread over two controllers, thus requiring the -Controller property to be called in New-NaVolClone and Add-NaNfsExport, which is forcing me to wrap the entire script in my Foreach controller loop.

Here's my the first part of my script that I'm having problems with:

$Snapshot = @()

$FlexClone = @()

#Create Object that connects to both FAS controllers

[object[]]$CDCFAS=$null

Foreach ($FAS in @("CDCFAS01", "CDCFAS02")) {

          $NewFAS=Connect-nacontroller $FAS

          $CDCFAS=$CDCFAS+$NewFAS

          }

#Gets weekley snapshot names of vmds_nfs volumes and creates flexclones from those volumes

Foreach ($ProdFAS in $CDCFAS) {

          $NFSVol = Get-NaVol -Controller $ProdFAS | where { $_.Name -like 'vmds_nfs_*'}

          $Snapshot += Foreach ($Vol in $NFSVol) {

                    Get-NaSnapshot -TargetName $Vol.Name -Controller $ProdFAS | where { $_.Name -notlike 'ATLFAS*' } | Sort-Object -Descending -Property Created | select -First 1

                    }

          Foreach ($Snap in $Snapshot) {

                    $NewClone = $ProdFAS.Name+'_'+($Snap.Created.ToShortDateString()).Replace("/","_")+'_'+$Snap.TargetName

                    New-NaVolClone -ParentVolume $Snap.TargetName -ParentSnapshot $Snap.Name -CloneVolume $NewClone -Controller $ProdFAS

                    Add-NaNfsExport -Persistent -Path /$NewClone -ActualPath /vol/$NewClone -ReadOnly $esxtststorage -Controller $ProdFAS

                    $NFSObject = New-Object System.Object

                    $NFSObject | Add-Member -MemberType NoteProperty -Name DatastoreName -Value $NewClone

                    $NFSObject | Add-Member -MemberType NoteProperty -Name Volume -Value $NewClone

                    $NFSObject | Add-Member -MemberType NoteProperty -Name NFSPath -Value /$NewClone

                    $NFSObject | Add-Member -MemberType NoteProperty -Name NFSHost -Value ($ProdFAS.ToString()+"d")

                    $NFSObject | Add-Member -MemberType NoteProperty -Name Controller -Value $ProdFAS

                    $FlexClone += $NFSObject

          }

}

The problem is that while my $Snapshot variable is populating with the 4 correct current snapshots, my Foreach-Object ($Snap ...) loop is populating my $Flexclone array with 6 objects.  I've listed the results of $Snapshot and $Flexclone below and highlighted the additional 2 objects that should not be there (Dark blue).  *Note:  If the volume name is like nfs_01, then the controller should be CDCFAS01.  Nfs02 = CDCFAS02.

Thanks for the help!

Do you have any VMs that span filers and/or datastores?

Check your weekly job in SMVI and check the "Spanning" tab.

My problem was a code problem.  I wasn't clearing my $Snapshot array variable in each loop, I was adding each result to the array.

Incorrect Code -->  $Snapshot += Foreach

Foreach ($ProdFAS in $CDCFAS) {

          $NFSVol = Get-NaVol -Controller $ProdFAS | where { $_.Name -like 'vmds_nfs_*'}

          $Snapshot += Foreach ($Vol in $NFSVol) {

                    Get-NaSnapshot -TargetName $Vol.Name -Controller $ProdFAS | where { $_.Name -notlike 'ATLFAS*' } | Sort-Object -Descending -Property Created | select -First 1

                    }

Correct Code --> $Snapshot = Foreach

Foreach ($ProdFAS in $CDCFAS) {

          $NFSVol = Get-NaVol -Controller $ProdFAS | where { $_.Name -like 'vmds_nfs_*'}

          $Snapshot = Foreach ($Vol in $NFSVol) {

                    Get-NaSnapshot -TargetName $Vol.Name -Controller $ProdFAS | where { $_.Name -notlike 'ATLFAS*' } | Sort-Object -Descending -Property Created | select -First 1

                    }

Thanks,

Nice script. Did you also write a script to reverse everything after the test is complete?
