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

Setting up a vPar to use NPIV HBAs

Configuring storage for a vPar with vHBAs

Storage can be provisioned for a vPar with a vHBA either before or after it starts up. In both cases, the vPar boots

successfully if it has a non-NPIV boot LUN configured. If it doesn’t have a boot LUN yet, then the vPar halts at EFI.

Once a virtual environment starts, the virtual port instance corresponding to the vHBA(s) assigned to it logs into the FC

fabric to which the physical HBA is connected. The port WWN assigned to the vHBA can be obtained using the

vparstatus command on the VSP. Once the port WWN has been noted, the server administrator should work with the

storage administrator to get the required storage provisioned. Present the LUNs to the port WWN corresponding to

the vHBA.

Note:

The steps for storage provisioning are exactly the same as those used for a

standalone system, except that in this case, the HBA and the WWN involved

are virtual in nature.

The vWWNs are highlighted in the output. These vWWNs can be used for LUN masking or fabric zoning.

Identifying vHBAs and LUNs in a vPar

The ioscan command, when run in a virtual environment, can be used to identify the NPIV HBA from the set of HBAs

seen in the vPar:

# ioscan -kfNd gvsd
