Multiple ParaVirtual SCSI Controller

[erki72]

Hi

I'm trying to run a simple script. I would expect 3 disks with 3 ParaVirtual adapters

Get-VM <yourvm> | New-HardDisk -CapacityGB 10 | New-ScsiController -Type ParaVirtual
Get-VM <yourvm> | New-HardDisk -CapacityGB 20 | New-ScsiController -Type ParaVirtual
Get-VM <yourvm> | New-HardDisk -CapacityGB 30 | New-ScsiController -Type ParaVirtual

But the result is as follows. Here I expect an adapter for each disk

What am I doing wrong?

My goal would be 3 Paravirtual controllers with 5 disks.
Distribute these over the 3 controllers. 
I would then assign it as follows:

Get-VM <yourvm>  | New-HardDisk -CapacityGB 15 -Datastore $datastoreVM -Controller "SCSI-Controller 1"

But if the script at the top doesn't work, I can't get any further.

Thanks

This seems to work for me.

Is that VM powered on?
Which PowerCLI version are you using?

Hi @LucD 

VM is powered off.

vCenter Version is 7.0.3
The only special thing is, it`s a 6.7 ESXi hosts (I know I know).

[LucD]

That is a relatively "old" PowerCLI version, I would definitely suggest upgrading.

The ESXi version shouldn't make a difference,

[erki72]

Same problem with newer Version 😞
Manifest 12.7.0.... VMware.PowerCLI

Can you try with the API method, just to eliminate it is not a vSphere issue.

$vm = Get-VM -Name <yourVM>

$ctrl = Get-ScsiController -VM $vm
$busNr = $ctrl.ExtensionData.BusNumber | Sort-Object -Descending | Select-Object -First 1

$hdSize = 10,20,30

$scsiKey = -1
$hdKey = -100

$spec = New-Object VMware.Vim.VirtualMachineConfigSpec

$hdSize | ForEach-Object -Process {
  $busNr++

  $ctrl = New-Object VMware.Vim.VirtualDeviceConfigSpec
  $ctrl.Operation = [VMware.Vim.VirtualDeviceConfigSpecOperation]::add
  $controller = New-Object VMware.Vim.ParaVirtualSCSIController
  $controller.Key = $scsiKey
  $controller.BusNumber = $busNr
  $ctrl.Device = $controller
  $spec.DeviceChange += $ctrl

  $hd = New-Object VMware.Vim.VirtualDeviceConfigSpec
  $hd.Operation = [VMware.Vim.VirtualDeviceConfigSpecOperation]::add
  $hd.FileOperation = [VMware.Vim.VirtualDeviceConfigSpecFileOperation]::create
  $disk = New-Object VMware.Vim.VirtualDisk
  $disk.Key = $hdKey
  $disk.ControllerKey = $scsiKey
  $disk.CapacityInKB = $_ * 1GB / 1KB
  $disk.UnitNumber = 0
  $back = New-Object VMware.Vim.VirtualDiskFlatVer2BackingInfo
  $back.DiskMode = [VMware.Vim.VirtualDiskMode]::persistent
  $back.FileName = ''
  $back.EagerlyScrub = $false
  $back.ThinProvisioned = $true
  $disk.Backing = $back
  $hd.Device = $disk
  $spec.DeviceChange += $hd

  $scsiKey--
  $hdKey--
}

$vm.ExtensionData.ReconfigVM($spec)

Crazy. That goes straight away.

My design or assignment should look something like this, is this also possible via the API? 
Where C:\ (system) and D:\ are created beforehand. It`s about E:\ - I:\

C:\ 0:0
D:\ 0:1
E:\ 1:2
F:\ 2:2
G:\ 2:0
H:\ 3:2
I:\ 3:0

Those partitions are created inside the Guest OS, that is not something PowerCLI or a vSphere API can do.
What you can do is use something like Invoke-VMScript to run a script inside the Guest OS.
And with that script create those partitions.
If the Guest OS is a Windows OS, you might look at PowerShell cmdlets like Get-Disk and New-Partition.

[erki72]

Now I expressed myself wrong.

Finally, after creating the controller and creating the disk, the VM "shell" should look like this.

We can do the rest with staging (in the OS)

[LucD]

I don't see what the issue is then with the code I provided.
With the unit- and bus-number you can specify where each new harddisk should go.

Since you went from 3 harddisks to 6 harddisks with different sizes than the original entry in this thread, you will have to adapt the data (disksize and number of entries).

You can also code the bus- and unit-number in a data array.
