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: 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: 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. Clearing the FICON management database Perform the following steps to clear RLIR and RNID records from the FICON management database. 1. Connect to the switch and log in as admin. 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. Using FICON CUP Host-based management programs manage switches using CUP protocol by sending commands to an emulated control device in the Fabric OS. An HP StorageWorks switch that supports CUP can be controlled by one or more host-based management programs or the Fabric OS tools provided by HP. A mode register controls the behavior of the switch with respect to CUP itself, and with respect to the behavior of other management interfaces. FICON Management Server mode (fmsmode) must be enabled on the switch to enable CUP management features. When this mode is enabled, Fabric OS prevents local switch commands from interfering with host-based management commands by initiating serialized access to switch parameters.
