  This PTF introduces a new release of ICP IOCP and is
  VERSION 3 RELEASE 3 LEVEL 0 (3.3.0) of the program.
  ICP IOCP supports the 2827 zEnterprise EC12.
  
  PROBLEM CONCLUSION:
  *
  ICP IOCP VERSION 3 RELEASE 3 LEVEL 0 (3.3.0) provides the
  following support:
    - The 2827 Models (H20, H43, H66, H89, HA1) are supported with
      SYSTEM=(2827,1).  IOCP ignores the MAXDEV keyword on the
      RESOURCE statement and reserves the maximum number of
      devices for this model.  Also, IOCP reserves the maximum
      number of channel subsystems (CSSs) and logical partitions
      for these models.
    - IOCP continues to use a variable amount of storage based
      on the type of IOCDS it is processing.  IOCP requires 130M
      for the 2827 CPC.
    - For 2827 model:
      + ESCON channels CHPID (TYPE=CBY, CVC, CTC, CNC)
        are no longer supported.

  Documentation Changes:
  There is a new publication "Input/Output Configuration
  Program User's Guide for ICP IOCP" which has order number
  SB10-7037-10.  The publication is available using Resource
  Link at http://www.ibm.com/servers/resourcelink by selecting
  section:
  Library > zEnterprise System, EC12
  *
  EC (Engineering Change) Information:
  This PTF level of ICP IOCP contains support for IBM
  zEnterprise EC12 central processor complexes (CPCs).
  See Usage Notes for further information.
  *
  Information on equivalent STAND-ALONE IOCP, z/OS IOCP, z/VM
  IOCP, and z/VSE IOCP follows:
  *
  *
    - Equivalent STAND-ALONE IOCP for ICP IOCP version 3.3.0 is
      in the listed EC's.  The EC's listed are the first levels
      shipped with this release of IOCP.
          EC       MACHINE TYPE
        H09173         2827
  *
    - Equivalent z/OS, z/VM, and VSE IOCP is shipped via the
      listed APARs.

  The EC level of the CPC can be determined from the Hardware
  Management Console or Support Element by doing the following:
    1. Open 'Task List' from the 'Views' area.
    2. Open 'Change Management' from the 'Task List Work Area'.
    3. Open 'Groups' from the 'Views' area.
    4. Open the group that contains the CPC you are interested
       in.
    5. Select the CPC.
    6. Open 'System Information' in the 'Change Management'
       tasks area.
  *
  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 determined from the Hardware Management Console
  or Support Element by doing the following (begin with step 7
  for the Support Element console):
    1. Open 'Task List' from the 'Views' area.
    2. Open 'Recovery' from the 'Task List Work Area'.
    3. Open 'Groups' from the 'Views' area.
    4. Open the group that contains the CPC you are interested
       in.
    5. Select the CPC.
    6. Open 'Single Object Operations' in the 'Recovery'
       tasks area.
    7. Open 'Task List' from the 'Views' area.
    8. Open 'CPC Configuration' from the 'Task List Work Area'.
    9. Open 'Groups' from the 'Views' area.
    10. Open 'Images' from the 'Groups Work Area'.
    11. Select the image to run STAND-ALONE IOCP.
    12. Open 'Input/output (I/O) configuration' in the 'CPC
        Configuration' tasks area.
    13. Select 'View' pull-down.
    14. 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 one of the listed EC's, you can
     still install this PTF and replace your existing ICP IOCP.
     The 2827 model must power-on reset with an IOCDS written by
     the ICP IOCP shipped by this PTF.  The 2084, 2086, 2094,
     2096, 2097, 2098, 2817 and 2818 models can power-on reset
     with an IOCDS written by the ICP IOCP shipped by this PTF.
     Also, the 2084, 2086, 2094, 2096, 2097, 2098, 2817 and
     2818 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. 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.
  3. 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.)
  4. If you are upgrading to a 2827 model, you must power-on
     reset with an IOCDS written for the 2827.  Following an
     upgrade, you cannot power-on reset with an IOCDS that was
     written for the prior CPC unless the 2827 IOCDS was written
     in preparation of an upgrade.
  5. If you are upgrading to a 2827 model, IBM recommends writing
     an IOCDS to your current 2097 or 2817 CPC as described here.
     Use IOCP execution paramenter CHECKCPC=NO or HCD option
     'Write IOCDS in preparation of upgrade'.  The IOCDS will be
     unusable until your CPC has been upgraded to a 2827.  Inform
     the installing service representative that you have
     pre-written a 2827 IOCDS and which IOCDS should be selected
     after the upgrade.
  6. Although FMID HIO1104 also includes support for
     IXPIOCP (3090, 9021, 9121, and 9221 only), IZPIOCP (2003,
     3000, 7060, 9021, 9121, 9672, and 9674 only), and IYPIOCP
     (2064 and 2066), these programs are not affected by this
     PTF.  Program IOPIOCP (3090 only) will be reused at some
     point in the future for a new processor.
