Abstract:
A mechanism is provided for moving control of storage devices from one adapter pair to another. In a trunked disk array configuration, moving the storage devices from one disk array to another disk array begins by attaching the downstream ports of the two independent disk arrays together. The mechanism redefines one set of the ports as upstream ports and through switch zoning makes a set of devices available to the second disk array adapters. By controlling zoning access and performing discovery one device port at a time, the mechanism transfers access and ownership of the RAID group from one adapter pair to another.
