How do I find my HBA WWN number on Linux?
How to find the HBA card and WWN port on Linux?
The HBA card number can be identified manually by filtering the associated files under the /sys file system. Files under sysfs provide information about devices, kernel modules, file systems, and other kernel components that are normally automatically mounted in /sys by the system.
How to find HBA details in Linux?
Re: FIND HBA DETAILS ON LINUX
You can probably find your HBA module in /etc/modprobe. Conf. There you can see with “modinfo” whether the module is for QLOGIC or EMULEX. Then use SanSurfer (qlogic) or HBA Anywhere (emulex) to get detailed and accurate information.
What is HBA WWN?
The term host bus adapter (HBA) is often used to refer to a Fiber Channel interface card. …Each Fiber Channel HBA has a Globally Distinguished Name (WWN) that is similar to an Ethernet MAC address in that it uses an IEEE-assigned OUI.
How do I find my WWN ID on Linux?
Here is a solution to find the WWN number of the HBA and scan the FC Luns.
What is the WWN number?
A World Wide Name (WWN) or Worldwide Identifier (WWID) is a unique identifier used in storage technologies such as Fiber Channel, Parallel ATA, Serial ATA, NVM Express, SCSI, and Serial Attached SCSI (SAS).
What is Lun on Linux?
In computer storage, a logical unit number, or LUN, is a number used to identify a logical unit, which is a device addressed by the SCSI protocol or storage area network protocols that encapsulate SCSI, such as B. Fiber Channel or iSCSI.
How to find LUN ID on Linux?
So the first device in the ls -ld /sys/block/sd*/device command matches the first device scene in the cat /proc/scsi/scsi command above. ie Host: scsi2 Channel: 00 Id: 00 Mon: 29 is 2:0:0:29. Check the highlighted part in the two commands to correlate. Another way is to use the sg_map command.
What is the difference between WWN and Wwpn?
A WWPN (World Wide Port Name) is physically assigned to a part of a Fiber Channel device, e.g. B. an FC HBA or SAN. … The difference between a WWN (WWNN) node is that it can be shared by some or all ports on a device, and a WWN (WWPN) port is a port that is necessarily unique to each port.
How to find wwpn number on linux?
Method 2: On Redhat 4 and earlier (including OEL and CentOS) the file is /proc/scsi/[adapter-type]/[n] contains HBA WWPN information. adapter-type: This can be qlaxxxx for QLogic adapters (or) lpfc for Emulex adapters. n refers to the number of HBAs available in the system.
How to Check HBA Speed on Linux?

Where is HBA WWN in Windows?
How do I check WWN and multipathing on Windows Server? Then run the “fcinfo” command in the command prompt. It shows that the HBA is connected to the server via WWN.
How does the HBA board work?
An HBA relies on the speed of each attached device for its performance. A RAID adapter, on the other hand, is an expansion card that turns the physical devices attached to it into a logical device (or RAID array) that the operating system then treats as a single physical drive.
How do I get my WWN number from the ILO?
