What is Fibre Channel NPIV?

NPIV or N_Port ID Virtualization is a Fibre Channel feature whereby multiple Fibre Channel node port (N_Port) IDs can share a single physical N_Port.

In which situations is NPIV useful select two?

It is used in storage networking techniques that utilize fiber channel-based ports to send and receive data between virtual machines (VM) and virtual storage area networks (SAN).

How do I find my Wwpn number Vios?

To locate the WWPN, complete the following steps:

  1. Log in as root.
  2. Enter lscfg -vl fcs x , where x is the adapter number. The network address is the Fibre Channel adapter port WWPN value. Notes: The lscfg -vl fcsx ROS level identifies the Fibre Channel adapter firmware level.

How do I map a Vfchost?

How to map the virtual FC client adapter to the physical FC (NPIV) port on the VIOS

  1. Login to the VIOS partition name identified in step 4d, as padmin user.
  2. Use lsdev command to determine the virtual FC server device name (vfchost#) configured on the virtual FC server adapter (remote_slot_num), 46.

What is the difference between NPV and NPIV?

While NPIV is primarily a host-based solution, NPV is primarily a switch-based technology. It is designed to reduce switch management and overhead in larger SAN deployments. Consider that every Fibre Channel switch in a fabric needs a different domain ID, and that the total number of domain IDs in a fabric is limited.

What is NPIV in Brocade?

NPIV stands for N_Port ID Virtualization. As you already know, physical server has it’s own HBA card with it’s own private WWN. This WWN can be logged into the Fabric, and (for example) storage array can mask some LUNs only to this WWN. This gives the possibility to provide independent storage access.

How does NPIV work?

NPIV is not limited to virtual server environments, but that is where the technology is best applied. By assigning virtual ports to the virtual machines (VMs) on a host, each VM can access the SAN storage as though accessing it directly through the physical port.

What is WWPN number?

A WWPN is a World Wide Port Name; a unique identifier for each Fibre Channel port presented to a Storage Area Network (SAN).

How do I find my WWPN number?

Issue the GO HARDWARE command from the IBM i operating system command line and select Option 3 to Work with storage resources. Next, type 7 beside the desired adapter (DCXX) to find the location code. The location code will match the location slot on the HMC. Page down, and the WWPN will be listed.

How do I create a virtual Fibre channel adapter in AIX?

From the Tasks menu, click Dynamic partitioning > Virtual Adapters. The Virtual Adapters window is displayed. Click Actions > Create > Fibre Channel Adapter. The Create Virtual Fibre Channel Adapter window is displayed.

What is NPIV switch?

NPIV stands for N-Port ID Virtualization. NPIV allows multiple initiators to logged in to the same physical target port. This feature is most useful in the SAN network where ESX Host, Blade Server, and UCS deployment.

How do I get a WWPN?

To locate the WWPN, perform the steps for the adapter you are using. After installing OneCommand Manager, to launch the application select Start > Programs > Emulex > OCManager. In the left panel, double-click on the host. It will expand to display the WWPN of the HBA installed on the host.
