This information from the Brocade Fabric OS FICON Administrator's Guide, Fabric OS v7.4.0 should answer your question:
- Addressing mode 1 (zero-based addressing):
- Sequential address binding
- Example scripts for binding ports (Mode 1):
Consider referring to the Brocade Fabric OS Administration Guide, v7.4, too. There, you will find that FICON will require one of the 256-area addressing modes one or two, but not the 10-bit addressing mode zero. Note the dependencies which should be taken into account for identifying the preferred addressing mode for your environment…
- 10-bit addressing
- 256-area addressing (mode 1 and mode 2)
- Zero-based addressing (mode 1)
I hope this will help you to find your answer?
Did you have noticed, that the most current Brocade FOS v8.1 will provide a powerful FICON logical switch feature which will include auto-configuration?
The information from the Brocade FOS 8.1 Admin Guide is:
FICON logical switch provides auto-configuration of the following, which simplifies the process of establishing a logical switch in the FICON environment:
- Insistent Domain ID (IDID) mode is set to on
- Routing policy is set to device-based routing
- Area mode is set to zero-based addressing
- SCC security policy is auto-defined with only its own WWN
- The created SCC policy is activated
- The fabric-wide consistency policy is set to strict SCC policy
- High Integrity Fabric (HIF) mode is enabled
- FMS mode is enabled if FICON CUP license is installed on the chassis
After the FICON mode logical switch is created, each port migrating into the logical switch must be bound to an address. Use the portaddress command to bind addresses. Any port that is not bound is kept disabled in the switch until it is bound to an address.
Please refer to the Brocade FOS Admin Guide 8.1.0 for more detailed information.
If you are using FOS bellow 8.1, consider to manually configure the same settings...
