Goal

This document describes the significance of a volume's "owning controller" and "preferred controller", and also explains how to change the "owning controller" setting of an individual volume via the Sun Storage Common Array Manager software.
This is often done in response to an xx.66.1010 alarm: "The following volume(s) is/are not managed by their preferred controller."
It also explains how changing the "owning controller" setting of a volume via CAM can result in a change of the "preferred controller" setting.
