Assigning priority to system operations relative to user operations
If system operations (for example, SnapMirror transfers or ndmpcopy operations) are negatively affecting the performance of user accesses to the storage system, you can use FlexShare to assign the priority of system operations to be lower than that of user operations for any volume.
Modifying the default priority
If you have not assigned a priority to a volume, then that volume is given the default priority for your storage system. The default value for the default priority is Medium. You can change the value of the default priority.
