Swapping port area IDs
If a port malfunctions, or if you want to connect to different devices without having to rewire your
infrastructure, you can move a port’s traffic to another port (swap port area ID ) without changing the I/O
Configuration Data Set (IOCDS) on the mainframe computer.
To swap port area IDs, refer to the "Swapping port area IDs" procedure in the Fabric OS Administrator's
Guide.
For more detail on the following commands that you will use to swap port area IDs, refer to the Fabric
OS Command Reference Manual:
• portSwapEnable
• portDisable
• portSwap
• portSwapShow
• PortSwapDisable
Important notes
Consider the following when swapping port area IDs:
• Ports that have been swapped cannot be moved to another logical switch.
• Ports with area OxFE or OxFF addresses cannot be swapped when FMS mode is enabled.
• You can use the portSwapShow command to display information about swapped ports in a switch.
• You can use the portSwap command to disable the port swapping feature. You cannot use the
portSwap command after this feature is disabled. The enabled state of the port swapping feature is
persistent across reboots and power cycles. Enabling and disabling the port swapping feature does
not affect previously executed port swapping operations.
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 Fabric OS. Fabric OS then validates each command before actually
implementing the command on the platform. If an error is encountered, the blade swap quits without
disrupting traffic flowing through the blades. If an unforeseen error does occur during the running of 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.
• Faulty blades cannot be swapped.
• Ports or blades with area OxFE or OxFF addresses cannot be swapped when FMS mode is
enabled.
• 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 must be in the same logical switch.
