Migrating from an MP Router to a 400 MP Router
This section 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.
Configurations
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
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 54 on
page 465.
Figure 54 shows an example of a simple non-redundant configuration.
Figure 54 Non-redundant router configuration
Follow the steps in ”To configure the new router:” on page 467 to change the configuration parameters to
be the same as on the old router, before it is introduced in the metaSAN.
