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          = <store method only>
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             = <store method only>

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       = <store method only>
   optrom             =
   reset             = <store method only>
   sfp                = ""
   uevent             = <store method only>
   vpd                = "?0"

  Class Device = "host14"
  Class Device path = "/sys/class/fc_host/host14"
fabric_name       = "0xxxxxxxxxxx"
issue_lip          = <store method only>
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             = <store method only>

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       = <store method only>
   optrom             =
   reset             = <store method only>
   sfp                = ""
   uevent             = <store method only>
   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             = <store method only>
....
