Abstract
Embodiments for an approach to resource optimization during consistency group formation associated with a global mirror environment is provided. The approach detects when a primary volume associated with the consistency group has completed transmitting its out-of-sync (OOS) data towards its associated secondary volume. A command is sent to create a next consistency group sidefile so further writes can be sent to the sidefile rather than queueing at the primary volume. The approach repeats this process for each primary volume associated with the global mirror environment until all primary volumes are complete. Commands are sent to disable writes to the associated sidefiles and to merge the data stored in the sidefiles into normal cache as the next consistency group becomes the current consistency group.
