Appendix A Migrating to Generation 3 8-Gbps Fibre Channel Switching Modules
Migration Procedures for the MDS 9513 Director
Activating the higher bandwidth capabilities of the MDS 9513 Fabric 2 modules can occur in one of two
ways:
• You can enter the reload command after a nondisruptive installation of the MDS 9513 Fabric 2
modules.
• You can power down the switch, install the MDS 9513 Fabric 2 modules, and then power up the
switch.
Both methods are disruptive. The latter method is a best practice because it requires fewer steps.
Depending on which method you choose, follow the instructions in either the
“Installing the MDS 9513
Fabric 2 Modules and Activating Higher Bandwidth by Reloading the Switch” section on page A-10 or
in the “Installing the MDS 9513 Fabric 2 Modules and Activating Higher Bandwidth by Powering Down
the Switch” section on page A-11.
Installing the MDS 9513 Fabric 2 Modules and Activating Higher Bandwidth by Reloading the Switch
Figure A-3 shows the process flow that occurs when you reload the switch to activate the higher
bandwidth capabilities of the MDS 9513 Fabric 2 modules.
Figure A-3 Strategy 2: Migration Process Flow
To reload the switch to activate the increased bandwidth capabilities of the MDS 9513 Fabric 2 modules,
follow these steps:
Step 1 Upgrade to Cisco NX-OS 4.1(1b). Refer to the upgrade procedure described in the MDS 9000 Family
CLI Configuration Guide.
Step 2 Verify that the switch is running Cisco NX-OS 4.1(1b) by entering the show version command.
Step 3 Enter the copy running-config startup-config command to save a copy of the current switch
configuration.
Step 4 Check the type of fabric modules that are present in the chassis by entering the show module xbar
command.
Step 5 If there are MDS 9513 Fabric 1 modules in the chassis, replace them according to the instructions in
the
“Installing MDS 9513 Fabric 2 Modules and Running Cisco SAN-OS 3.x” section on page A-5.
Step 6 Enter the show hardware fabric-mode command to display information about Generation 3 module
support.
The following example shows the output of the show hardware fabric-mode command, which indicates
that support for the MDS 9000 48-port and 24-port 8-Gbps Generation 3 modules has not been enabled
for the switch.
