For more information about controller ownership, see the Subsystem Management Window online help.

This reference contains commands and parameters that are current with the latest storage management software. If you are managing storage subsystems running firmware for previous releases, not all of these commands may be supported. See the for a complete list of commands and their associated firmware levels.

Caution: Resetting a controller makes the controller unavailable for I/O until the reset is complete. If a host is using logical drives owned by the controller being reset, the I/O directed to the controller will be rejected. Before resetting the controller, either verify that the logical drives owned by the controller are not in use or ensure there is a multi-path driver installed on all hosts using these logical drives.

restore logical drives to their preferred controller owners

Back to the top

Base Command and Required Parameters

Back to the top

reset storageSubsystem logicalDriveDistribution

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.

Example

Back to the top

Command statement:

reset storageSubsystem logicalDriveDistribution

Execution result:

All storage subsystem logical drives are redistributed to 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.
