Use this option to move logical drives back to their preferred owners
Caution: If you use this option without a multi-path driver on the hosts, stop I/O to the logical drives while this operation is in progress to prevent application errors.
Important: This option is not available if all logical drives are currently owned by their preferred controllers, or if no logical drives exist on the storage subsystem.
1 |
Select the storage subsystem from the Subsystem Management Window. Then, select either the Storage Subsystem >> Redistribute Logical Drives pull-down menu option, or Redistribute Logical Drives from the right-mouse pop-up menu. Result: The Redistribute Logical Drives confirmation dialog is displayed. |
2 |
Select Yes. Result: A dialog displays the redistribution progress while the logical drives are being moved to their preferred owners. |
3 |
Select OK. Result: The progress dialog is dismissed and all storage subsystem logical drives are associated with their preferred owners. Selecting a logical drive in the Logical View displays an association dot next to the 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 multi-path host driver might be an additional requirement. You may also need to make operating system modifications to recognize the new I/O path to the logical drives. |
