D 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 87 shows an example of a simple non-redundant configuration. Figure 87 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 88. Follow the steps in "To configure the new router:" on page 545 to change the configuration parameters to be the same as on the old router, before it is introduced in the metaSAN. . Figure 88 Configuration during the upgrade The switch Domain ID and backbone fabric ID of the new FC router can be identical. Once the metaSAN is stable, EX_Ports on the new router are active, the old router can be taken out of the setup. Fabric OS 6.2 administrator guide 543
