    From PdAt, "link_speed" attribute shows that this adapter
    supports 4G speed as well. It does not match with what
    "port_speed_supp" attribute is set to.   This need to be
    fixed.
    
    PdAt:
            uniquetype = "adapter/pci/77102224"
            attribute = "link_speed"
            deflt = "auto"
            values = "auto,1G,2G,4G"
            width = ""
            type = "R"
            generic = "DU"
            rep = "sl"
            nls_index = 18
    
    PdAt:
            uniquetype = "adapter/pci/77102224"
            attribute = "port_speed_supp"
            deflt = "100000"
            values = "100000"
            width = ""
            type = "R"
            generic = ""
            rep = "nr"
            nls_index = 0
    

Local fix

Problem summary

  • Qlogic FC Adapter(uniquetype=adapter/pci/77102224) which is
    running with a link speed of 4 gbit however the fcstat command
    is reporting a supported port speed of 1 gbit.
    

Problem conclusion

  • Modified the filelds "deflt" and "values" to 400000 of
     PdAt attribute "port_speed_supp" for Qlogic 4G adapter.
