What is the difference between vSCSI and Npiv?

Compared to VSCSI, an NPIV storage environment typically requires less effort to be configured and maintained as there is no multipath device driver, virtual target device creation, and administration of corresponding volume device mappings required on the VIOS instance.

What is NPIV in VIOS?

This document explains how to configure NPIV (N-Port ID Virtualization also known as Virtual Fibre). To configure NPIV, you need to create a Server Fibre Channel Adapter in the VIOS partition and a Client Fibre Channel Adapter in the client partition.

What is vSCSI?

A virtual SCSI (vSCSI) disk is a resource which can be a SCSI disk, or a volume or file in a VIO Server that is exported to a virtual IO client. IBM vSCSI LUNs implement a sub-set of the SCSI protocol. The two main limitations are: Persistent reservations (SCSI3 – PGR) are not implemented.

What is the correct definition of 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 Vscsi in AIX?

Virtual SCSI is based on a client/server relationship. The Virtual I/O Server owns the physical resources and acts as server or, in SCSI terms, target device. The client logical partitions access the virtual SCSI backing storage devices provided by the Virtual I/O Server as clients.

How do I uninstall Vscsi disk?

In the case where the virtual scsi disk to be replaced is the only physical volume in the volume group, then remove the volume group, via:

1. # exportvg
2. This will deallocate the physical partitions and will free up the virtual disk.
3. In the case where there are more than one physical volumes.
