Data evacuation is a background process used to move data off specific physical media (like a shelf or data pack) so it can be removed safely. Purity is designed to handle dynamic changes to evacuation requests efficiently.
If an evacuation is already running and additional hardware needs to be evacuated, the Implementation Engineer does not need to stop the current job or wait for it to finish. The correct procedure is to issue a new evacuation command specifying the additional packs or shelves. Purity will intelligently update the existing background job to include the new targets, queuing the data movement logic to ensure all specified hardware is cleared. This "add-to-flight" capability saves time and administrative overhead compared to cancelling and restarting the entire workflow.
