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

Configuring an NPIV HBA with vPar commands

There are no changes to the options available with the vPar commands in order to support NPIV. All that is required

is the use of the new NPIV I/O syntax with the –a option.

The following sections describe how an NPIV resource is specified and the existing vPar commands that can be used

for configuring/managing them.

vparcreate/vparmodify—to add an NPIV resource

An NPIV HBA resource can be specified using vparcreate when the vPar is being created or using vparmodify after

vPar creation. The resource string format presented in the Specifying an NPIV resource section (above) should be

used to specify the vHBA.

Example: To create a vPar, “vPar1”, with four virtual CPUs and a vHBA on /dev/fcd0 using the default bus and

device values, and allowing GUIDMgr to select the virtual WWNs:

vparcreate -p vPar1 –a cpu::4 -a hba:avio_stor::npiv:/dev/fcd0

Example: To add a vHBA on /dev/fcd1 to bus 1, address five on the vPar “vPar1” using a virtual PWWN of

0x50060b00006499a8 and a virtual NWWN of 0x50060b00006499a9:

vparmodify –p vPar1 \

-a hba:avio_stor:1,5,0x50060b00006499a8,0x50060b00006499a9:npiv:/dev/fcd1

NOTE:

The vPar must be in the DOWN state to add an NPIV HBA. The vparmodify

command cannot be used to change any attribute of the NPIV HBA once it is

created.

vparstatus

The vparstatus output now includes the NPIV HBAs. All other vparstatus output is the same as for AVIO devices.

For example:

# vparstatus -vp vPar1
