Status of CloneVirtualDisk_Task in vSphere 4.0 u 1

There are a couple of older posts about limitations to the situations in which CloneVirtualDisk_Task will work. I thought I would post my recent findings for the benefit of all.

This is against vSphere 4.0 u1 / ESX 4.0 u1 using VMware-vSphere-SDK-for-Perl-4.0.0-161974

1. Calling the method against VC still doesn't work

The VirtualDiskManager object on which you call the method is no longer null, but when you call the method the task fails with the error "The requested operation is not implemented by the server". Thus you must still call the method against an ESX server instead.

2. Force still doesn't work

Despite setting the 'force' property in the task to 1, the task still fails with an error that the file exists

3. When the destination file exists, the error message contains the name of the source file

In discovering 2, I found 3. I checked loads, and I was definitely specifying the source and destination files the right way around. Here's the out put of my script:

Copying data from [VDI1-00006] VUKMH1-005_1/VUKMH1-005-vdm-user-disk-D.vmdk to [VDI1-00003] VUKMI-004/VUKMI-004-vdm-user-disk-D.vmdk...

ERROR: Clone task has failed. Error text: Cannot complete the operation because the file or folder /vmfs/volumes/49108494-f0558240-3705-001f296371fa/VUKMH1-005_1/VUKMH1-005-vdm-user-disk-D.vmdk already exists

Err...what? Then I checked the hostd.log:

Riiight. The line stating that my destination file exists kind of gives away that I specified them the right way round. The error message, however, says different. So don't believe the error messages...
