Error description

  • In Spectrum Control, the SVC subsystem port zero buffer credit
    value is received directly from the SVC storage device and has
    certain limitations in terms of what traffic it measures.  For
    example, Spectrum Control customers may notice a difference
    between the switch port metric value & the SVC port metric
    value, as SVC is unable to measure the raw traffic through the
    ports as some of it is hidden by the Emulex hardware.
