Abstract:
1. Apparatus for use in a storage system comprising a Fibre Channel fabric having a database that associates Fibre Channel names and Fibre Channel addresses of Fibre Channel ports coupled to it, the apparatus comprising: a plurality of groups of logical units of storage; at least one physical port coupled to the groups through which the groups are coupled to the fabric; each group assigned a unique virtual port address for each physical port to which it is coupled; a first said group comprising a source virtual array, the source virtual array having one or more source virtual ports coupled to the fabric, each source virtual port having a source virtual port name and a source virtual port address; a second said group comprising a destination virtual array, the destination virtual array having one or more destination virtual ports coupled to the fabric, each destination virtual port having a destination virtual port name and a destination virtual port address; logic for copying all data resident on the source virtual array to the destination virtual array; logic for exchanging the source virtual port names with the destination virtual port names so that source virtual ports have the destination virtual port names and the destination virtual ports have the source virtual port names; logic for causing the fabric to reload its name server database so that the database associates the source virtual port names with the destination virtual port addresses and the destination virtual port names with the source virtual port addresses.
