I have this small block of code that goes through each disk and sets it to thin provisioned while setting up the job spec.
if (_vmThinProvision)
{ ConverterStorageParamsManagedTargetDiskParams targetDiskParams = new ConverterStorageParamsManagedTargetDiskParams(); converterStorageParams.targetDiskParams = new ConverterStorageParamsTargetDiskParams[_computerInfo.hardwareInfo.storage.disk.Length]; for (int diskCount = 0; diskCount < _computerInfo.hardwareInfo.storage.disk.Length; diskCount++) { targetDiskParams.sourceDiskId = _computerInfo.hardwareInfo.storage.disk[diskCount].diskId; Console.WriteLine(targetDiskParams.sourceDiskId); targetDiskParams.diskType = "vmfsMonolithicFlatThinProvisioned"; targetDiskParams.datastoreName = _vmDatastoreName; converterStorageParams.targetDiskParams[diskCount] = targetDiskParams; }
}
Lets take an example where a system has 3 disks. In the above code, if I just set up each disk manually instead of having it in a loop (same exact code, just taking the loop out and hard-coding the array index), it works fine. Each disk and volume gets its own ID and the conversion works properly.
For some reason when I implement the loop, it seems to pick the same disk 3 times instead of the 3 different disks and, as would be expected, confuses the heck out of the VSS service. See the log below from the source system.

You may noticed I put a little console.writeline in there to show me the ID. They are different at that point. Sometime between there and the job submission process the IDs get all fudged up.
Again, if I just take out the loop and hard-code the indexes, it works fine. Any ideas? This one has really stumped me.
Thanks,
