  • Closed as program error.

Error description

  • It appears method buildPathsFromPathQueryResult incorrectly
    processes the target WWNN field when the query is issued to a
    target volume. The result of the incorrect processing, is that
    the source WWNN is stored in the target WWNN field in the
    database. Later, when paths are being established, this
    incorrect source WWNN is used on the establish paths command.
    This results in the 0FA1 error, since the source and target WWNN
    are the same.
    

Local fix

Problem summary

  • The WWNN of the DS8000 source and target volumes were not
    correct (they were set to 0) when trying to create the PPRC
    paths to the DS8000s.
    Target WWNN selection is in error while issuing a start command
    while multiple paths exist to a single target LSS.
    

Problem conclusion

  • Prior to this fix, the create PPRC path command may work
    depending on which LSS the path command was issued to. This
    really depends on the order of the LSS's within the path
    mapping. In example, the first LSS within the path mapping will
    get the WWNN of the source box. If the path happens to be a
    loopback path (within the same box), then the "correct" WWNN
    will be returned. Otherwise the LSS's will geturn 0 for the
    WWNN. The code will now choose the correct WWNN.
    

Temporary fix
