While doing an online copy in the 3PAR, we create a temporary snapshot of source volume to do the data copy operation. Online copy is a feature in 3PAR whereby a copy initiated on a source volume , and when the data copy is in progress, the target volume of the copy is immediately available for volume attachment and performing I/O is allowed on that volume Resynching the source and the destination volume is done automatically by the 3PAR internally. Reasoning behind removing the temporary snapshot of the source volume is that, internally 3PAR creates a temporary snapshot and extra snapshot created by Cinder 3PAR Driver is un-necessary. Also this temporary snapshot is not cleaned up on the completion of online copy operation. The presence of the temporary snapshot during the volume copy operation is confirmed by running the "showtask" on the asynchronous task id.
