What is HBA card Linux?

Fibre Channel (FC) Host Bus Adapters(HBA) are interface cards that connects the host system to a fibre channel network or devices. The two major manufacturers of FC HBAs are QLogic and Emulex and the drivers for many HBAs are distributed in-box with the Operating Systems.

How do I find my WWN number in Linux?

Here is a solution to find WWN number of HBA and scan the FC Luns.

  1. Identify the number of HBA adapters.
  2. To get the WWNN (World Wide Node Number) of HBA or FC card in Linux.
  3. To get the WWPN (World Wide Port Number) of HBA or FC card in Linux.
  4. Scan the newly added or rescan the existing LUNs in Linux.

What is Lun in 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 by Storage Area Network protocols that encapsulate SCSI, such as Fibre Channel or iSCSI.

What is difference between WWN and Wwpn?

A WWPN (World Wide Port Name) is physically assigned to a part in a Fibre Channel device, such as a FC HBA or SAN. … The difference between a node WWN (WWNN), is it can be shared by some or all ports of a device, and a port WWN (WWPN), is one which is necessarily unique to each port.

How do I replace my HBA card in Linux?

Planning Steps:

  1. Locate the failed HBA adapter on the physical machine.
  2. Note the WWPN of the HBA that will be replaced.

Where is HBA WWN on Windows?

How to check WWN and Multipathing on Windows Server? then, run “fcinfo” command in Command Prompt. It will show up HBA connected to the server with WWN.

What is WWN storage?

A World Wide Name (WWN) is a unique identifier that is assigned to a manufacturer by the Institute of Electrical and Electronic Engineers (IEEE) and hard-coded into a Fibre Channel (FC) device. WWNs are important when setting up a storage area network (SAN).

What is the difference between HBA and NIC?

The main difference is the type of storage/switch you are connecting to. HBA stands for Host Bus Adapter and is used to connect to block level storage such as Fibre Channel, SATA or SCSI. … NIC stands for Network Interface Adapter and is used to connect ethernet storage to a switch or server.

How does HBA card works?

An HBA relies on the speed of the individual devices connected to it for its performance. A RAID adapter, on the other hand, is an add-in card that takes the physical devices connected to it and turns them into a logical device (or RAID array), which the operating system then sees as a single physical drive.

Where is San storage in Linux?

If you want to check the LUNs that are provisioned to the server, run “fdisk -l” or “cat /proc/scsi/scsi”. Keep in mind that you may see duplicates if you have multiple paths to the SAN.
