    15989
    Multiple INOPDUMPs can be requested when a devices fails, when
    in most cases only the first reason for the failure should be
    dumped.  This is particularly likely when the reason for the
    failure in message IST1578I is module ISTSRIS8, code 100, which
    is a devices internal read error.
    15252
    The DLC is acquiring storage for the entire ICM space when it
    only needs to acquire storage for how much of the space it
    actually uses and backs.
    16036
     PCIE EVENT CODE = 0002 occurs after a failover occurs for a
    link.
    16011
    The  DLC is not retrying temporary failures enough times on the
    datapath.
    

Problem conclusion

  • 15989
    Only take one INOPDUMP when all stacks are made inoperative for
    a single device failure.
    15252
    Acquire only the storage used within the ICM space.
    16036
     Corrected EZBSRUTL to set the the associated staging buffer DMA
    address in the PSAC being modified for the new link.
    Previously, the staging buffer DMA address associated with the
    failing link was left in the PSAC.  This can lead to invalid DMA
    addresses being calculated if the new formatted PSAC is not
    transmitted over the new link.  The invalid DMA address will
    result in a PCIE EVENT CODE 0002 when the adapter reads from the
    invalid DMA address.
    16011
    Retry for an appropriate length of time on the datapath.
