Is there a change that needs to be made to the function used for binding Excel to support 2010?
# Function used for binding to Excel
function Invoke([object]$m, [string]$method, $parameters)
{ $m.PSBase.GetType().InvokeMember($method, [Reflection.BindingFlags]::InvokeMethod, $null, $m, $parameters, [System.Globalization.CultureInfo]“en-US”) }

Had one of our SQL query gurus take a look and we had to make the following adjustments for this platform.

SELECT VPX_GUEST_DISK.VM_ID, VPX_GUEST_DISK.PATH, VPX_GUEST_DISK.CAPACITY,
CONVERT(bigint, VPX_GUEST_DISK.CAPACITY) / 1048576 AS ‘CAPACITY_MB’, VPX_GUEST_DISK.FREE_SPACE,
CONVERT(bigint, VPX_GUEST_DISK.FREE_SPACE) / 1048576 AS ‘FREE_MB’, VPX_HOST.ID,
VPX_HOST.DATACENTER_ID, VPX_HOST.DNS_NAME, VPX_VM.ID, VPX_VM.DATACENTER_ID, VPX_VM.FILE_NAME,
VPX_VM.LOCAL_FILE_NAME, VPX_VM.POWER_STATE, VPX_VM.GUEST_OS, VPX_VM.GUEST_STATE, VPX_VM.MEM_SIZE_MB,
VPX_VM.NUM_DISK, VPX_VM.DNS_NAME, VPX_VM.IS_TEMPLATE, VPX_VM.HOST_ID
FROM [database_name].[dbo].VPX_GUEST_DISK, [database_name].[dbo].VPX_HOST, [database_name].[dbo].VPX_VM
WHERE [database_name].[dbo].VPX_VM.ID = [database_name].[dbo].VPX_GUEST_DISK.VM_ID AND [database_name].[dbo].VPX_HOST.ID = [database_name].[dbo].VPX_VM.HOST_ID

Brendan – I don’t know off the top of my head, but your timing couldn’t be better. I was just about to try this query against my 4.1/SQL 2008 setup. I’ll let you know what I discover.

Any idea what VMware vCenter and SQL platforms/releases are associated with SQL query above?

We’re trying to run against vCenter 4.1, SQL 2008 and getting syntax errors. Our presumption is that the DB schema may be different thus throwing an error.

Thanks for the pingback, Scott. You are correct on there being a vCenter plugin for obtaining free disk space – Rich Garsthagen wrote a plug-in called VCPlus that accomplishes this (http://www.run-virtual.com/?page_id=145). I used it for a while a few years back and had mixed results (some VM’s were just not being reported on). Rich and I emailed back and forth a few times trying to figure it out but I dropped off as new projects demanded time. VCPlus also offers a few other neat options such as showing snapshot status and syncing the DNS name with the VC display name for each guest. Rich also has a sample script for the VI Perl Toolkit called VMDiskFree that can report on guest free space.
