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.
