Redhat Server檢視HBA和WWN的方法 (2011-01-30 18:13)


在redhat下檢視wwn是件麻煩事，有的人說用vendor自帶的工具查，有的說可以看/proc/scsi/下的某個目錄檔案，偏偏我遇到的，這些都看不見，雖然使用的是QLogic，但是系統沒安裝，未經許可也不方便隨便安裝這些軟體，只能另想辦法。

查了很多資料，終於知道有個命令systool可以實現

[ 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把兩個hba識別為host13和host14（嗯~~風格和solaris很不一樣）。一般情況下，一個卡
的node_name和port_name 就是指該HBA卡的wwn，他們的值是一樣的。速度啊什麼的該列的引數都給你列出來了。

還有一個藉助systool能看到你的hba卡和哪些裝置連線（或者說能看到哪些儲存）。


[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              =
