II08325: VTAM CTC (OR MPC) ACTIVATION FAILS WITH MSGIST380I ACTLINK 081C003C -- RESOLVED AT VTAM 4.3 FOR AHHC (APPN) USERS.

Error description

• When an ESCON CTC SCTC device used for communications by VTAM
  does not come up online during MVS system initialization at IPL,
  any attempt to issue a VTAM VARY NET,ACT,ID=Linename involving
  that device, will fail with MSGIST380I ACTLINK 081C003C.
  The definition for SNA sense 081C003C indicates that the device
  has not been made available by the operating system.
    For the VTAM activate to succeed, the device must be VARY'd
  online using the MVS VARY online command.  Once it is
  accessible, reissue the VTAM VARY NET,ACT command.
  
  CONFIGURATION explained:
    One of the two systems using the SCTC device has it attached
  via a CTC type chpid.  The other system using the SCTC device
  has it attached via a CNC type chpid.  Hereafter, these
  systems will be referred to as the CTC system and the CNC
  system, respectively.
        ______            ____            ______
       |      |   CTC    /    \   CNC    |      |
       | SYSx |<-------->|SCTC|<-------->| SYSy |
       |______|  chpid   \____/  chpid   |______|
  
    The SCTC will not come up online to the CNC system when the
  CTC system does not have a logical path established to the
  device.  This condition will occur, for example, when the
  CTC system has done an I/O Interface Reset (but NOT a System
  Reset).  An I/O Interface Reset would have occurred if a
  recovery action of F1 was selected from the SYSDEF frame and
  the system subsequently entered a disabled wait state.  One
  common circumstance under which a system will enter a disabled
  wait state is when it is partitioned out of a SYSPLEX.
    Other conditions causing the SCTC to not come up online to
  the CNC system are:
    - The processor on the CTC side is powered off.
    - The CTC and CNC chpids attach to an ESCON director
      and either port is blocked, or the path within the
      director is prohibited.
    - The CTC chpid has been configured off from the system
      (hardware) console.
  

Local fix

• If the CTC system is in a disabled wait state, system reset
  it or IPL it before IPL'ing the CNC system.
    If the CNC system has already been IPL'd but the SCTC device
  is offline to it, the device must be MVS VARY'd online in order
  for a VTAM VARY NET to be successful.  It cannot be MVS VARY'd
  online with the CTC system still in the disabled wait state.
  Either system reset the CTC system or IPL it.
