  Documentation Changes:
  There is a new publication "Input/Output Configuration
  Program User's Guide for ICP IOCP" which has order number
  SB10-7183-00.  The publication is available at
  https://www.ibm.com/docs/en/systems-hardware/zsystems
  by selecting the appropriate IBM Z model and then
  section Library Overview.
  *
  EC (Engineering Change) Information:
  This PTF level of ICP IOCP contains support for IBM z17
  central processor complexes (CPCs).
  See Usage Notes for further information.
  *
  Information on equivalent STAND-ALONE IOCP, z/OS IOCP, and z/VM
  IOCP follows:
  *
  *
    - Equivalent STAND-ALONE IOCP for ICP IOCP version 7.1.0 is
      in the listed EC's.  The EC's listed are the first levels
      shipped with this release of IOCP.
            EC      MACHINE TYPE
        P30924.007      9175
  *
    - Equivalent z/OS and z/VM IOCP is shipped via the
      listed APARs.
        OPERATING SYSTEM       APAR
             z/OS            OA67614
             z/VM 7.3        VM66898
             z/VM 7.4        VM66899

  The EC level of the CPC can be determined from the Hardware
  Management Console or Support Element by doing the following:
    1. From Navigation pane, select 'Systems Management' on
       HMC or 'System Management' on Support Element.
    2. Select 'Systems' on HMC.
    3. Select the CPC you are interested in.
    4. Expand the 'Change Management' tasks area.
    5. Open 'System Information' in the 'Change Management'
       tasks area and look for Description 'Input/Output
       Configuration Program' to identify the appropriate EC
       level.
  *
  The STAND-ALONE IOCP version and release can be determined by
  looking at the header lines of the IOCP reports produced by
  STAND-ALONE IOCP.  The STAND-ALONE IOCP version and release can
  also be found in IOCP message ICP073I in an I/O Configuration
  Source file that was processed by STAND-ALONE IOCP.  The
  STAND-ALONE IOCP version and release can also be determined
  from the Hardware Management Console or Support Element by
  doing the following (begin with step 6 for the Support Element
  Console):
    1. Select 'Systems Management' from Navigation pane.
    2. Select 'Systems'.
    3. Select the CPC you are interested in.
    4. Expand the 'Recovery' tasks area.
    5. Open 'Single Object Operations' in the 'Recovery'
       tasks area to connect to the Support Element.
    6. Select 'System Management' from Navigation pane.
    7. Select the CPC or an activated partition.  (Note that
       an activated partition is required to write an IOCDS.)
    8. Expand 'Configuration' from the tasks area.
    9. Open 'Input/output (I/O) Configuration' in the
       'Configuration' tasks area.
    10. Select 'View' pull-down.
    11. Select 'Configuration Program Level'.

  Usage Notes:
  1. If you are currently using a release of ICP IOCP and you do
     not plan on upgrading to the listed EC level, you can
     still install this PTF and replace your existing ICP IOCP.
     The 2827, 2828, 2964, 2965, 3906, 3907, 8561, 8562, 3931, and
     3932 models can power-on reset with an IOCDS written by the
     ICP IOCP shipped by this PTF.  Also, the 2827, 2828, 2964,
     2965, 3906, 3907, 8561, 8562, 3931, and 3932 models can still
     power-on reset with an IOCDS that was written by your
     previous release of ICP IOCP.  There is no requirement that
     you write an IOCDS with the ICP IOCP shipped by this PTF and
     perform a power-on reset after the PTF has been installed.
  2. If you are currently using a release of ICP IOCP for a 9175
     model but do not plan on upgrading to the listed EC level,
     you can still install this PTF and replace your existing ICP
     IOCP.  There is no requirement that you write an IOCDS with
     the ICP IOCP shipped by this PTF and perform a power-on reset
     after the PTF has been installed.
  3. Any IOCDS previously created by an ICP version of IOCP
     (z/OS, VM, VSE, or STAND-ALONE) can be reported on by the
     ICP version of IOCP shipped by this PTF.
  4. Any IOCDS previously created by another version of IOCP
     (e.g. IYP IOCP) cannot be reported on by the ICP version of
     IOCP shipped by this PTF or by the STAND-ALONE equivalent
     version of the ICP IOCP program.  (For HCD users, HCD manages
     the correlation of IOCP versions to CPC model for you.)
  5. If you are upgrading to a 9175 model, you MUST write a 9175
     IOCDS to your current 8561 or 3931 CPC as described here or
     write a 9175 IOCDS after the upgrade is completed.  Prior
     to the upgrade, use IOCP execution parameter CHECKCPC=NO or
     HCD option 'Write IOCDS in preparation of upgrade'.  The
     IOCDS will be unusable until your CPC has been upgraded to
     a 9175.  Inform the installing service representative that
     you have pre-written a 9175 IOCDS and which IOCDS should be
     selected after the upgrade.
