Hi Graeme, currently running with Toolkit v3.1.1.181 and seems this still has not been solved. In your case you had Snapdrive disks returned (not complete though) but in my case I had no SD Luns returned at all - eventhough 5 LUNs were created, connected and configured on the Win2008 host.
If I run as follows, I get the non-negative number required message in return.
qt
PS C:\> Get-NaHostDisk -DataOntap
Get-NaHostDisk : Non-negative number required.
Parameter name: byteCount

Goal is to run the NA Powershell reclamation script which does not work for obvious reasons; so I was hoping you have a workaround in the meantime. All feedback appreciated, thanks.
