Need to check the port status of my fibre channel HBA

决议

The state of the port can be checked within the /sys/class directory either via

$ systool -c fc_host -v    from sysfsutils package
Class = "fc_host"

  Class Device = "host10"
  Class Device path = "/sys/class/fc_host/host10"
    fabric_name         = "0x200000e08b8068ae"
    issue_lip           = 
    node_name           = "0x200000e08b8068ae"
    port_id             = "0x000000"
    port_name           = "0x210000e08b8068ae"
    port_state          = "Linkdown"
    port_type           = "Unknown"
    speed               = "unknown"
    supported_classes   = "Class 3"
    supported_speeds    = "1 Gbit, 2 Gbit, 4 Gbit"
    symbolic_name       = "QLE2460 FW:v5.06.03 DVR:v8.03.07.15.05.09-k"
    system_hostname     = ""
    tgtid_bind_type     = "wwpn (World Wide Port Name)"
    uevent              = 

    Device = "host10"
    Device path = "/sys/devices/pci0000:00/0000:00:04.0/0000:08:00.0/host10"
      optrom_ctl          = 
      reset               = 
      uevent              = 
:
.

or if sysfsutils package is not installed

$ grep -v "zZzZ" -H /sys/class/fc_host/host*/port_state
sys/class/fc_host/host10/port_state:Linkdown
sys/class/fc_host/host11/port_state:Online
sys/class/fc_host/host12/port_state:Online
sys/class/fc_host/host8/port_state:Online
sys/class/fc_host/host9/port_state:Online
