HP-UX Virtual Partitions 6.0 Administrator Guide

To add an NPIV resource – vparcreate and vparmodify
You can specify an NPIV HBA resource using vparcreate while creating the vPar or using the
vparmodify command after the vPar is created. For information about the resource string format
used to specify the NPIV HBA, see the “Specifying an NPIV HBA resource” (page 18) section.
IMPORTANT: Before creating an NPIV HBA, ensure that the physical HBAs on the system support
NPIV. You can use the fcmsutil command to determine whether NPIV is supported. An alternate
way to determine which card supports NPIV is to add the product number of the card that currently
supports NPIV or point them to quickspec if it is available for vPars v6.0.

Create a vPar named vPar1 with 4 virtual CPUs and an NPIV HBA created on /dev/fcd0 using
the GUID server to assign port and node WWNs.
vparcreate -P vPar1 -c 4 -a hba:avio_stor::npiv:/dev/fcd0
Add an NPIV HBA created on /dev/fcd1 using a virtual port WWN of 0x50060b00006499b9
and virtual node WWN of 0x50060b00006499ba to the vPar named vPar1. Obtain the port
and node WWNs from your storage administrator or other source.
vparmodify -P vPar1 -a hba:avio_stor:,,0x50060b00006499b9,
0x50060b00006499ba:npiv:/dev/fcd1
NOTE: The vparmodify command cannot be used to change any attribute of the NPIV HBA
after it is created.
To view – vparstatus
The vparstatus command output includes the NPIV HBA in the I/O details for vPars that have
the NPIV HBA configured. All other vparstatus output remains unchanged.
To delete a NPIV resource – vparmodify
The vparmodify command is used to delete an NPIV HBA from a vPar. For the deletion to take
effect, you must stop and start the vPar.
