Chapter 2 — Architecture Overview
World Wide Names for Partitions
The World Wide Name (WWN) displayed for each partition on the Shared
Library Services screen is the WWN of the controller (RIM) that provides
the robotic control path for the partition (the exporting controller). The
WWN is based on the physical location of the RIM in the library and
remains constant even if the RIM is replaced. The new RIM assumes the
location‐based WWN.

the partitions have the same WWNN and the same World Wide Port
Name (WWPN). However, the partitions will have different LUNs
under those controllers, starting at LUN zero (0).
and another to use Port B, the WWNN/WWPN of port A will start with
21 and the WWNN/WWPN of port B will start with 22. In this case the
ports are independent. However, both of the partitions will show the
WWN for Port A only.
the WWNN will be the same for both ports but the WWPN will be
different. This scenario is a type of redundant path to the robotics.
For more information about WWNs, log on to the portal (see Accessing
the Technical Support Portal on page 492), open the Knowledge Base,
and in the KBA field, enter 01764 to access the article Spectra Library
World Wide Names (WWNs) for QIPs (the article discusses F‐QIPs; the
concepts are the same for a RIM).
