What is vmware NPIV?

NPIV stands for N-Port ID Virtualization. It is an ANSI T11 standard that describes how a single Fibre Channel Physical HBA port can register with a fabric using several worldwide port names (WWPNs), what might be considered Virtual WWNs.

What is the use of HBA?

An HBA allows a host system and connected storage devices to communicate with each other. HBAs support specific types of devices, such as Serial ATA (SATA), Serial Attached SCSI (SAS), and Fiber Channel. Not all HBAs support all types of devices.

What is FCoE NPV?

The FCoE NPV feature is an enhanced form of FCoE Initialization. Protocol (FIP) snooping that provides a secure method to connect FCoE-capable hosts to an. FCoE-capable FCoE forwarder (FCF) device.

What does NPIV stand for in VMware?

NPIV stands for N-Port ID Virtualization. It is an ANSI T11 standard that describes how a single Fibre Channel Physical HBA port can register with a fabric using several worldwide port names (WWPNs), what might be considered Virtual WWNs. This in turn means that since there a multiple Virtual HBAs per physical HBA,…

Do you need NPIV for ESXi virtual machine?

The physical HBAs on the ESXi host must support NPIV. If the physical HBAs do not support NPIV, the virtual machines on that host start using the WWNs of the physical HBAs for LUN access. Each virtual machine can have up to 4 virtual ports.

How do I disable NPIV in virtual machine?

Right-click a virtual machine in the inventory and select Edit Settings. Click the VM Options tab and expand Fibre Channel NPIV. (Optional) Select the Temporarily Disable NPIV for this virtual machine check box. Select an option for assigning WWNs. To leave WWNs unchanged, select Leave unchanged.

How to enable NPIV on Fibre Channel VM?

Select the VM that will use NPIV and then go to the VM Properties, select the Options tab, and check the Fibre Channel NPIV setting: As you can see, there are No WWNs currently assigned. Next, we need to map an RDM to the VM in order to enable NPIV.
