Hot-swapping FibreBridge 6500N bridges to create a pair of FibreBridge 7600N bridge

To hot-swap one or two FibreBridge 6500N bridges to create a configuration with a pair of FibreBridge 7600N bridge, you must replace the bridges one at a time and follow the correct cabling procedure. The new cabling is different from the original cabling.

About this task

You can also use this procedure if the following conditions are true:

• You are replacing a pair of FibreBridge 6500N bridges that are both connected to the same stack of SAS storage.

• You previously replaced one FibreBridge 6500N bridge in the pair, and your storage stack is configured with one FibreBridge 6500N bridge and one FibreBridge 7600N bridge.

  In this case, you should begin with Step 3.

The following diagram shows an example of the initial configuration, in which four FibreBridge 6500N bridges are connecting two SAS storage stacks:

1. Using the following guidelines, hot-swap the top FibreBridge 6500N bridge with a FibreBridge 7600N bridge using the procedure in Hot-swapping a FibreBridge 6500N bridge with a FibreBridge 7600N bridge:

   • Connect the FibreBridge 7600N bridge FC1 port to the switch or controller.

     This is the same connection that was made to the FibreBridge 6500N bridge FC1 port.

   • Do not connect the FibreBridge 7600N bridge FC2 port at this time.

   The following diagram shows that bridge_A_1a has been replaced and is now a FibreBridge 7600N bridge:

   
   
   
2. Confirm connectivity to the bridge-connected disks and that the new FibreBridge 7600N is visible in the configuration: run local sysconfig -v

   Example

   node_A_1> run local sysconfig -v

3. Using the following guidelines, hot-swap the bottom FibreBridge 6500N bridge with a FibreBridge 7600N bridge using the procedure in Hot-swapping a FibreBridge 6500N bridge with a FibreBridge 7600N bridge:

   • Connect the FibreBridge 7600N bridge FC2 port to the switch or controller.

     This is the same connection that was made to the FibreBridge 6500N bridge FC1 port.

   • Do not connect the FibreBridge 7600N bridge FC1 port at this time.

   
4. 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:
