Overview of the stand-alone version of IOCP

Edit online

Start and control the stand-alone version of IOCP from the CPC console. The CPC console is a logical console available from the Hardware Management Console through the CPC Console task or from the Support Element (SE).

Run the stand-alone version of IOCP to define I/O configuration data when you operate your system before installing z/OS, VM, or z/VSE, or when you operate your system with a control program other than these programs.

Start IOCP by selecting the I/O Configuration task from the Support Element or Hardware Management Console. Briefly, the functions you can request are as follows:
  1. Import a card-image statement file from a USB flash drive or from an FTP location.
  2. Export a card-image statement file to a USB flash drive or to an FTP location.
  3. Edit IOCP card-image data. You can supply card-image data by using the disassemble or import functions, or the stand-alone IOCP editor.
  4. Build an IOCDS read from the I/O configuration source (IOCS) file on the SE hard disk. IOCP writes the IOCDS to the SE after a successful build.
  5. Disassemble an IOCDS from the SE hard disk to create an IOCS file on the SE hard disk.

For a description of the stand-alone version of IOCP, see Running the stand-alone version of IOCP. Figure 1 shows an overview of the processing performed by the stand-alone version of IOCP.

  1. You control IOCP from the Support Element or Hardware Management Console.
  2. The card-image input contains IOCP statements from the Support Element hard disk. You can also load card images into the stand-alone IOCP editor from an I/O configuration source (IOCS) file.
  3. IOCP processes IOCP window commands from the CPC console to control IOCP functions. If wanted, you can use the stand-alone editor to inspect, create, or modify card images from an IOCS file using the CPC console. Use the CPC console to:
    • Import and export card image statements files
    • Disassemble an IOCDS
    • Build an IOCDS
    • Print configuration reports
  4. Configuration reports allow you to check the I/O configuration data as defined in the IOCDSs.
  5. Build a new IOCDS from an IOCS file, or disassemble an existing IOCDS to generate an IOCS file. The IOCDSs and IOCSs reside on the Support Element hard disk. When you perform power-on reset, the IOCDS is loaded into the hardware system area (HSA). (The I/O subsystem uses the data in the HSA to control I/O requests.)
