Detaching several Direct LUNs from a VM is supported in 3.5.0 (and probably in 3.4 too, I admit I did not bisect when exactly this was added). From the Disks subtab under the VMs maintab: 1. Select multiple disks using the CTRL button 2. Click Remove (or right click->remove) 3. DO NOT CHECK THE "Remove Permanently" CHECKBOX!!! 4. Click OK to confirm
