balancing after adding nl-disks to HP3PAR 7400

We added NL-disks to 2 of our 3PAR 7400 systems.
On both 3PAR's now we see in IMC that the old NL-disks are used for 100% and the new disks for 33-45%.
What can we do to equally divide the data over all the NL-disks?

Thanks for the answer. Tunesys is running on the first 3PAR. Started Sep 5. Ending in a few days?

tunesys - Analyzes and automatically corrects space usage imbalances. You can run it from CLI with tunesys command or from Management Console Provisioning > Tune System.

PS! HP 3PAR Autonomic Rebalance aka System Tuner aka tunesys functionality is included in 3PAR 7000 base Operating System Suite and does not require Dynamic Optimization license.

Ditto to what he said, tunesys will do the trick. If you have DO and prefer to spread it out you could TuneVV individual VVs, otherwise the cli guide should have the tunesys switches.
