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.
Synchronous SnapMirror updates are not considered system operations, because they are performed from NVRAM when the primary operation is initiated. Therefore, synchronous SnapMirror updates are affected by the volume priority of the target volume, but not by the relative priority of system operations for that volume.
vol_name is the name of the volume for which you want to set the priority of system operations.
Example
The following command sets the priority level for the dbvol volume as high as possible while setting system operations for that volume to 30. priority set volume dbvol level=VeryHigh system=30
