Error description

  • After a storage port reset / imp or adding luns on the
    array
    a pdisc validation from the VIO npiv client may fail and
    result in a LOGO from the storage port. This will cause a
    momentary delay in IO processing as a full re-login will
    be needed. This is due to the NPIV client setting the
    wrong wwn / wwpn in the pdisc payload
