HP-UX vPars 6.0 N-Port ID Virtualization (NPIV) - A brief overview

ManualsBrandsHP ManualsSoftwareHP-UX Virtual Partitions (vPars) Software

Note that the ioscan output listing of targets and LUNs on the vHBA in the vPar is the same as a listing of SAN LUNs

on a standalone system (other than the driver used to access the device):

Identifying the VFC Controller’s creation in a virtual environment

If a vPar with NPIV is not started, no VFC controllers will be shown in the “ioscan –kfnNd fcd” output on the VSP.

Below is an example where the vPar is down as shown by vparstatus command and the output of “ioscan –kfnNd

fcd” run on the VSP.

If a vPar with NPIV entries is started, you can identify if the VFC is created on the VSP as follows:
