Use this option to move arrays (and their associated logical drives) back to their preferred owners. Typically, multi-path drivers move arrays from their preferred controller owner when there is a failure along the connection between the host and the Storage Subsystem.
Important: This option is not available if all arrays are currently owned by their preferred controllers, or if no logical drives exist on the Storage Subsystem.
Caution: If you use this option without a multi-path driver installed on the hosts, stop I/O to the logical drives while this operation is in progress to prevent application errors. You may also need to make operating system modifications to recognize the new I/O path to the logical drives.
How to Redistribute Arrays
1 | From the Subsystem Management Window, either select the Storage Subsystem >> Redistribute Arrays pull-down menu option or use the right mouse button to select the Storage Subsystem in the Logical View. Then, select Redistribute Arrays from the pop-up menu. Result: The Redistribute Arrays confirmation dialog is displayed. |
2 | Select Yes. Result: All Storage Subsystem arrays are redistributed back to their preferred owners. Selecting an array in the Logical View displays an associated controller in the Physical View that is both the current owner and the preferred owner. Important: Under certain application host operating system environments, a reconfiguration of the host driver might be an additional requirement. |
