Redhat Server查看HBA和WWN的方法

在RedHat下查看wwn是件麻烦事，有的人说用vendor自带的工具查，有的说可以看/proc/scsi/下的某个目录文件，偏偏我遇到的，这些都看不见，虽然使用的是QLogic，但是系统没安装，未经许可也不方便随便安装这些软件，只能另想办法。

查了很多资料，终于知道有个命令systool可以实现

[ tmp]# systool -c fc_host -v
Class = "fc_host"

  Class Device = "host13"
  Class Device path = "/sys/class/fc_host/host13"
    fabric_name         = "0xxxxxxxxxxxxx"
    issue_lip           =
    node_name           = "0xxxxxxxxxxx"
    port_id             = "0x331400"
    port_name           = "0xxxxxxxxxxx"
    port_state          = "Online"
    port_type           = "NPort (fabric via point-to-point)"
    speed               = "4 Gbit"
    supported_classes   = "Class 3"
    supported_speeds    = "1 Gbit, 2 Gbit, 4 Gbit"
    symbolic_name       = "QLE2460 FW:v4.04.09 DVR:v8.03.01.04.05.05-k"
    system_hostname     = ""
    tgtid_bind_type     = "wwpn (World Wide Port Name)"
    uevent              =

    Device = "host13"
    Device path = "/sys/devices/pci0000:00/0000:00:0a.0/0000:02:00.0/host13"
      ct                  =
      els                 =
      fw_dump             =
      nvram               = "ISP "
      optrom_ctl          =
      optrom              =
      reset               =
      sfp                 = ""
      uevent              =
      vpd                 = "?0"

  Class Device = "host14"
  Class Device path = "/sys/class/fc_host/host14"
    fabric_name         = "0xxxxxxxxxxx"
    issue_lip           =
    node_name           = "0xxxxxxxxxxx"
    port_id             = "0x331400"
    port_name           = "0xxxxxxxxxxx"
    port_state          = "Online"
    port_type           = "NPort (fabric via point-to-point)"
    speed               = "4 Gbit"
    supported_classes   = "Class 3"
    supported_speeds    = "1 Gbit, 2 Gbit, 4 Gbit"
    symbolic_name       = "QLE2460 FW:v4.04.09 DVR:v8.03.01.04.05.05-k"
    system_hostname     = ""
    tgtid_bind_type     = "wwpn (World Wide Port Name)"
    uevent              =

    Device = "host14"
    Device path = "/sys/devices/pci0000:80/0000:80:0b.0/0000:81:00.0/host14"
      ct                  =
      els                 =
      fw_dump             =
      nvram               = "ISP "
      optrom_ctl          =
      optrom              =
      reset               =
      sfp                 = ""
      uevent              =
      vpd                 = "?0"

可以看出os把两个hba识别为host13和host14（嗯~~风格和solaris很不一样）。一般情况下，一个卡
的node_name和port_name 就是指该HBA卡的wwn，他们的值是一样的。速度啊什么的该列的参数都给你列出来了。

还有一个借助systool能看到你的hba卡和哪些设备连接（或者说能看到哪些存储）。

[tmp]# systool -c fc_remote_ports -v|more
Class = "fc_remote_ports"

  Class Device = "0-0"
  Class Device path = "/sys/class/fc_remote_ports/rport-13:0-0"
    dev_loss_tmo        = "60"
    fast_io_fail_tmo    = "off"
    node_name           = "0xxxxxxxxxxxx"
    port_id             = "0x330400"
    port_name           = "0xxxxxxxxxxx"
    port_state          = "Online"
    roles               = "FCP Initiator"
    scsi_target_id      = "-1"
    supported_classes   = "Class 3"
    uevent              =
....
