OW01131: FIX FOR SUG APAR OY66486

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• Switched logical units become inactive after RNAA failures.
  When physical unit connection is broken, the LUs are left
  inactive.  Operator intervention is required to recover LUs.
  This is a fix for SUG apar OY66486.

  ****************************************************************
  Current processing of RNAA errors results in the logical unit
  being placed in an inactive status.  This makes it necessary for
  operator intervention to recover the LU.  The processing for
  ACTLU failures places the LU in a connectable (CONCT) status
  after the failure, making operator intervention unnecessary.
  (Apar OY01784 made ACTLU processing work in this manner.)
  The processing for ACTLU and RNAA should be consistent.  So RNAA
  failure processing will be changed to put the LU in CONCT status
  This will make it unnecessary for operator intervention to
  recover the LU after the physical connection with the PU is
  broken.
  It should be noted that while the connection is up that incurred
  the RNAA failure, the LU will be in CONCT status, but will be
  unusable.  If the problem that caused the RNAA failure is
  temporary, a vary activate of the LU will (assuming the next
  RNAA is successful) place the LU in active status (ACTIV),
  and it will be usable.
  

Problem conclusion

• ISTACCSU is changed to make the desired state CONCT for
  switched LUs with RNAA failures.
