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 packageClass = "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_statesys/class/fc_host/host10/port_state:Linkdownsys/class/fc_host/host11/port_state:Onlinesys/class/fc_host/host12/port_state:Onlinesys/class/fc_host/host8/port_state:Onlinesys/class/fc_host/host9/port_state:Online
