Text from OA32369 included below.

OA30776 appears to have been intended to resolve some problem related to
timing of LSNCB PU PAB processing and delay that until some other event
had occurred.

OA32369 talks about LSNCB having some value and PAB processing not being
scheduled, which sounds to me like OA30776 may have had some bad side
effects of causing a processing delay in some cases for which the
delayed processing is never resolved.

In any event, the rather nebulous "In certain conditions" description in
OA32369 doesn't give much clue as to whether this is a rare or common
problem, or what kind of devices might be affected other than the
reference to "switched PU".  I don't know if use of OSA FENET SNA is
significant here, but at this point this is the only interface we have
through which we can drive 3174 R controllers, and for us the failure on
these devices was 100% with no circumvention.

Since IBM is offering an APAR fix, I would hope that means they have
already diagnosed and understand the problem.

  ERROR DESCRIPTION:
  In certain conditions, the ACTPU processing for a switched PU
  might fail with the following message:
   IST380I ERROR FOR ID = xxxxxx - REQUEST: ACTPU, SENSE: 08010000
  A display of the switched PU resource will show state of PDISC
  to indicate pending discontact response and the PU fails to
  activate and remains hung.
  The associated LSNCB will show LSNFSM value of x'9C' for
  LSN_SW_CONNECT_REQUESTED state and the RCCRNAA bits in RCCBITAN
  flags for the switched PU control block will show value of x'4'
  for RCCRNAT4 to indicate that CONTACTED x'0A' has been received.
  The VIT trace will show that the switched PU got sidequeued
  (non-zero LSNSIDEQ) and the PAB did not get scheduled to update
  the switched PU to the correct state of CONCT.


  LOCAL FIX:
  None. There is no certainty that forced deactivation and
  re-activation of the switched resources will work.
