Cabling the second bridge FC port when adding FibreBridge 7600N bridge to a configuration

To provide multiple paths to the storage stacks, you can cable the second FC port on each FibreBridge 7600N bridge when you have added the FibreBridge 7600N bridge to your configuration.

Before you begin

The zoning must have been adjusted to provide zones for the second FC ports.

  1. Cable the FC2 port of the top bridge to the correct port on FC_switch_A_2.



  2. Cable the FC1 port of the bottom bridge to the correct port on FC_switch_A_1.



  3. Confirm connectivity to the bridge-connected disks: run local sysconfig -v

    The output shows the disks attached to the initiator ports on the controller, and identifies the shelves connected to the FC-to-SAS bridges:

    Example

    node_A_1> run local sysconfig -v
