Abstract
A method for use in a first storage array, comprising: detecting whether a second storage array has designated the first storage array as a locally-preferred storage array, the detecting being performed when a first link between the second storage array and a witness node is down; setting a value of a first configuration setting to indicate that the first storage array is designated as a system-preferred storage array, the value of the first configuration setting being stored in a memory of the first storage array, the value of the first configuration setting being set only when the second storage array has designated the first storage array as a locally-preferred storage array; detecting, by the first storage array; and when the second link is down, assuming one of an active role or a passive role based, at least in part, on the value of the first configuration setting.
