5 Blade swapping 1. Connect to the switch and log in using an account assigned to the admin role. 2. Enter the portSwapEnable command to enable the command for port swapping. 3. Enter the portDisable command to disable the two ports to be swapped. 4. Enter the portSwap command to swap the ports. Any port in the switch can be used as the alternate for any other port within the same switch. 5. Re-enable the ports using the portEnable command. 6. Enter portSwapDisable to disable the command for port swapping. Example of port swapping switch:admin> portswapenable switch:admin> portdisable [slot/] portA [slot/]portB switch:admin> portswap [slot/] portA [slot/]portB switch:admin> portenable [slot/] portA [slot/]portB switch:admin> portswapdisable • slot is the slot number of the port blade for a system with port blades (optional). • portA is the original port number. • portB is the alternate port number. You can use the portSwapShow command to display information about swapped ports in a switch. You can use the portSwap command to disable the portswap feature. You cannot use the portSwap command after this feature is disabled. The enabled state of the portswap feature is persistent across reboots and power cycles. Enabling and disabling the portswap feature does not affect previously executed portswap operations. See the Fabric OS Command Reference for additional details about the portSwap command. Blade swapping Blade swapping allows you to swap one blade with another of the same type; in this way, you can perform a FRU replacement with minimal traffic disruption. The entire operation is accomplished when the bladeSwap command runs on the Fabric OS. The Fabric OS then validates each command before actually implementing the command on the enterprise-class platform. If an error is encountered then blade swap quits without disrupting traffic flowing through the blades. If an unforeseen error does occur during the bladeSwap command, an entry will be made into the RASlog and all ports that have been swapped as part of the blade swap operation will be swapped back. On successful completion of the command, the source and destination blades are left in a disabled state allowing you to complete the cable move. Blade swapping is based on port swapping and has the same restrictions: • Shared area ports cannot be swapped. • Ports that are part of a trunk group cannot be swapped. • GbE ports cannot be swapped. • Swapping ports between different logical switches is not supported. The ports on the source and destination blades need to be in the same logical switch. • Undetermined board types cannot be swapped. For example, a blade swap will fail if the blade type cannot be identified. 60 FICON Administrator's Guide 53-1001771-01
