Use this option only under the guidance of a representative.
This option is not available if all of the logical drives are currently owned by their preferred controllers, or if no logical
drives exist on the storage subsystem.
Under certain application host type environments, a reconfiguration of the multi-path host driver might be an additional requirement.
You might also need to make operating system modifications to recognize the new I/O path to the logical drives.
Select the storage subsystem, and select Advanced >> Recovery >> Redistribute Logical Drives.
Click Yes.
A dialog shows the redistribution progress while the logical drives are being moved to their preferred owners.
Click OK.
