Preferred Owner

The preferred owner of a logical drive or array is the controller of an active-active pair that is designated to own these logical drives. The current owner is the controller that currently owns the logical drive or array.

If the preferred controller is being replaced or undergoing a firmware download, ownership of the logical drives is automatically shifted to the other controller, and that controller becomes the current owner of the logical drives. This is considered a routine ownership change and is reported with an informational entry in the event log.

There can also be a forced failover from the preferred controller to the other controller because of I/O path errors. This is reported with a critical entry in the event log, and will be reported by the Enterprise Management software to e-mail and SNMP alert destinations.

The preferred owner for a logical drive is initially selected by the controller when the logical drive is created. Use the Array >> Change Ownership option to change the preferred owner for a selected array.

To shift logical drives away from their current owners and back to their preferred owners, use the Storage Subsystem >> Redistribute Logical Drives option.
