Step 1: Configuring the IODF

This example shows how to configure two ports of a FICON® or FICON Express feature for FCP.

Procedure

Define two FCP CHPIDs. Both are given the number 50, one for channel subsystem 0 and one for channel subsystem 1:

CHPID PATH=(CSS(0),50),SHARED,                                *
      PARTITION=((LP01,LP02,LP03,LP04,LP05,LP06,LP07,LP08,LP09*
      ,LP10,LP11,LP12,LP13,LP14,LP15),(=)),PCHID=160,TYPE=FCP
CHPID PATH=(CSS(1),50),SHARED,                                *
      PARTITION=((LP16,LP17,LP18,LP19,LP20,LP21,LP22,LP23,LP24*
      ,LP25,LP26,LP27,LP28,LP29,LP30),(=)),PCHID=161,TYPE=FCP

Assign FCP control unit 5402 to the new CHPIDs:

CNTLUNIT CUNUMBR=5402,PATH=((CSS(0),50),(CSS(1),50)),UNIT=FCP

Define several FCP devices starting with device number 5400:

IODEVICE ADDRESS=(5400,002),CUNUMBR=(5402),                   *
      PARTITION=((CSS(0),LP01),(CSS(1),LP16)),UNIT=FCP
IODEVICE ADDRESS=(5402,002),CUNUMBR=(5402),                   *
      PARTITION=((CSS(0),LP02),(CSS(1),LP17)),UNIT=FCP

…

IODEVICE ADDRESS=(5460,144),CUNUMBR=(5402),                   *
      PARTITION=((CSS(0),LP15),(CSS(1),LP30)),UNIT=FCP
