How to view hba and wwn on RedhatServer

Checking wwn under RedHat is troublesome. Some people say that they use tools provided by vendor, and some say they can view a directory file under/proc/scsi, these are invisible. Although QLogic is used, the system is not installed, and it is not convenient to install the software without permission. You can only find another method. Check a lot of information, finally know that there is a command ool can achieve [tmp] # systool-cfc_host-vClass = "fc_host"

I checked a lot of information and finally learned that there is a command systool to implement

[Tmp] # ool OOl-c fc_host-v
Class = "fc_host"

Class Device = "host13"
Class Device path = "/sys/class/fc_host/host13"
Fabric_name = "0 xxxxxxxxxxxxx"
Issue_lip =
Node_name = "0 xxxxxxxxxxx"
Port_id = "0x331400"
Port_name = "0 xxxxxxxxxxx"
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 = "0 xxxxxxxxxxx"
Issue_lip =
Node_name = "0 xxxxxxxxxxx"
Port_id = "0x331400"
Port_name = "0 xxxxxxxxxxx"
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 =

We can see that the OS recognizes two hbas as host13 and host14 (HMM ~~ The style is different from that of solaris ). Generally, a card
Node_name and port_name are the wwn of the HBA, and their values are the same. Speed and other parameters in this column are listed for you.

You can also use the plug-in tool to see which devices your plug-in is connected to (or which storage devices you can see ).

[Tmp] # ool OOl-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 = "0 xxxxxxxxxxxx"
Port_id = "0x330400"
Port_name = "0 xxxxxxxxxxx"
Port_state = "Online"
Roles = "FCP Initiator"
Scsi_target_id = "-1"
Supported_classes = "Class 3"
Uevent =
