Migrating from an MP Router to a 400 MP Router
Introduction to MP Router upgrades
This appendix describes how to upgrade routers in your fabric with the least disruption, while providing
better performance and scalability. Improper implementation could lead to a change in the xlate Domain
IDs and proxy device PIDs, which may cause disruption in the fabric.
FC routers are deployed in different configurations in a fabric. Those configurations are listed in the
following pages and steps have been provided to integrate the 400 MP Router in a fabric with the HP
StorageWorks Multi-protocol Router. The figures in the following pages demonstrate how the 400 MP
Router should be integrated into a specified configuration, whether it is non-redundant, redundant, or in a
dual backbone configuration.
Non-redundant configuration
Figure 59 shows an example of a simple non-redundant configuration.
Figure 59 Non-redundant router configuration
A 400 MP Router can be inserted into an existing metaSAN so that the old and new configuration form
one redundant configuration. Before implementing this design, configure the new router’s EX_Ports and
fabric IDs with the same configuration parameters. The new configuration will look like Figure 60.
Follow the steps in ”To configure the new router:” on page 473 to change the configuration parameters to
be the same as on the old router, before it is introduced in the metaSAN.
