How to Convert Thick Disks to Thin Disk

[shandy4473]

Good Morning Everyone,

I have a question. I have an ESXi 4.0 setup where I have a number of VMs that are thick disks. I would like to convert those to thin disks. Can this be performed with PowerCLI or the vmware management assistant. If so, does the VM have to be powered off or can it be left on? I would prefer the easiest way to perform this action.

Thanks

You can also do this conversion via the vSphere client and storage vMotion.

Hi,

You can do this using Storage vMotion, but you going to need a second datastore in order to migrate the virtual disks and transform them from thick to thin format. You can do a Storage vMotion within the same datastore, but the format change isn't applied.

I think you cannot change the disk format using the vCLI or vMA. Perhaps PowerCLI let you accomplish this task.




Regards / Saludos
