Current Owner

The current owner of a logical drive is the controller of an active-active pair that currently owns the logical drive. If you select an array in the Subsystem Management Window Logical View, any controllers owning logical drives within the array are designated with an association dot in the Physical View.

The current owner may not be the preferred owner. Preferred controller ownership of the logical drive may shift from the preferred controller when it is being replaced or is undergoing a firmware download. 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 alert e-mail and SNMP destinations.

Use the Change Controller Ownership pull-down menu option to change both the current and the preferred owner for a selected array.

To shift logical drives away from their current owners and back to their preferred owners, use the Redistribute Arrays pull-down menu option.
