FRU failures

Swapping ports
If a port malfunctions, or if you want to connect to different devices without having to re-wire your
infrastructure, you can move a port’s traffic to another port (
swap ports
) without changing the I/O
Configuration Data Set (IOCDS) on the mainframe computer.
To swap ports, perform the following steps (refer to the example that follows):
1. Connect to the switch and log in as
admin
.
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).
In the following example:
• 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.
Refer to the
Fabric OS Command Reference Manual for additional details about the
portSwap
command.

2. To remove all the RLIR records from the local RLIR database, enter
ficonclear rlir
.
3. To remove all the RNID records marked “not current” from the local RNID database, enter
ficonclear rnid
.
