Disk handling

Hi

1. What is the best way to determine if the disk has been created?

Vdc vdc = ...

DiskCreateParamsType diskCreator =  ...

Disk disk = vdc.createDisk(diskCreator); //3

Waiting for the disk creation is is needed or call (3) assures tha the disk has been created?

2. Is it possible to create a snapshot of an independent disk?

Disk disk = ....;

Disk snapshopt = disk.snapshot();

If this is not possible on the vCloud layer is it possible to do this at vCenter / data store level?

3. Is is possible to clone an independent disk? So create an identical copy of an already existing

disk?

Disk original = ...;

Disk clone = original.cloneDisk(); ///

Thanks,

Denes
