FICON SAN configuration and setup has a different set of requirements than distributed systems SANs. Since FICON fabrics are relatively static once configured, many mainframe data centers lack the expertise to configure the SAN switches.


The attached document greatly simplifies FICON SAN configuration with a step-by-step illustrated guide to implementing a FICON SAN. FICON best practices are discussed along with numerous tips for an easy to maintain and trouble free high-performance SAN. These tips include recommended MAPS policies for  FICON environments, common security concerns in mainframe environments, and much more.


Includes instructions for:


  • Basic configuration
  • Virtual fabric
  • Cascaded FICON
  • FICON configuration wizard
  • FICON zoning
  • Recommended MAPS policy for FICON
  • Forward error correction
  • Fabric security policy
  • Insistent Domain ID
  • Device Based Routing (DBR)
  • High integrity fabric (HIF)


For channel path planning, there is a discussion of control units relative to port address and link address. The Excel spreadsheets in the links below provide useful documentation as well as link address planning for DASD, Tape, and FCTC devices.


The planning sheets are especially useful in virtualized (logically partitioned) switch environments. Should manually binding link addresses to a port become necessary, there is a sheet with the Brocade FOS bind commands. There are no macros in the work books. Formulas are used for all calculations of link address and bind commands. They do not replace the CHPID Mapping Tool.
