Common FICON issues
5
Symptom Channel path with 2-byte addressing does not come online
Probable cause and recommended action
Ask the operator what CHPID he is attempting to bring online. In FICON environments, only the
egress ports are defined in the IOCDS. The CHPID number of the channel appears in the node list,
but only if the channel path has logged in. If the channel path will not come online, it may not have
completed a Fibre Channel fabric login. If this is the case, you will have to rely on customer
documentation to determine what switch port the channel is connected to.
Next, ask the operator what type of error message they are getting. An IOS error message is
reported when there is an error external to the host; an IEE error message indicates something is
wrong internal to the host.
Fabric Not Configured Properly
• Make sure that the insistent domain ID is set and the domain IDs are unique for all switches in
the fabric.
• Make sure that the same binding method is used on all switches in the fabric.
• Scroll through the node list and make sure there are no invalid attachments.
• Make sure that the re-routing delay is turned off.
Cabling
Validate that cables are connected where intended.
When using multimode fiber, make sure that all fiber is either all 50u or all 62.5u. A common
mistake is to mix 50u and 62.5u fiber cables, which causes errors at patch panels.
Example of a Boxed Channel
In this example, the customer complained that the CHPIDs with 2-byte addressing did not come
online. He was instructed to configure the CHPID offline and then try to configure the CHPID back
online.
