HP StorageWorks Fabric OS 5.X Administrator Guide (AA-RVHWB-TE, September 2005)

Fabric OS 5.x administrator guide 111
FRU failures
To display FRU failure information, connect to the switch, log in as admin, and issue one of the
following commands:
• For the local switch: ficonshow ilir
• For all switches defined in the fabric: ficonshow ilir fabric
Swapping ports
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 ports) without changing the I/O
Configuration Data Set (IOCDS) on the mainframe computer.
To swap ports, perform the following steps (see the example that follows):
1. Connect to the switch and log in as admin.
2. Issue the portSwapEnable command (to enable the command for port swapping).
3. Issue the portDisable command to disable the two ports to be swapped.
4. Issue 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. Reenable the ports using the portEnable command.
6. Issue 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.
See the HP StorageWorks Fabric OS 5.x command reference guide for additional details about the
portSwap command.
Clearing the FICON management database
You can clear RLIR and RNID records from the FICON management database as follows:
1. Connect to the switch and log in as admin.
2. To remove all the RLIR records from the local RLIR database, issue ficonclear rlir.
3. To remove all the RNID records marked not current from the local RNID database, issue
ficonclear rnid.
Using FICON CUP
Host-based management programs manage switches using CUP protocol by sending commands to an
emulated control device in Fabric OS. An HP switch that supports CUP can be controlled by one or more
host-based management programs, as well as by HP tools.
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
