HP Integrity VM 4.3 N-Port ID Virtualization - A brief overview

Configuring an NPIV HBA with HP Integrity VM commands

hpvmcreate / hpvmmodify—to add an NPIV resource

An NPIV HBA resource can be specified using hpvmcreate when the VM is being created or using hpvmmodify after

VM 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 guest, “Guest1”, 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:

hpvmcreate –P Guest1 –c 4 -a hba:avio_stor::npiv:/dev/fcd0

Example: To add a vHBA on /dev/fcd1 to bus 1, address 5 on the guest “Guest1” using a virtual PWWN of

0x50060b00006499a8 and a virtual NWWN of 0x50060b00006499a9:

hpvmmodify –P Guest1 \

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

NOTE:

For this operation to take effect, the VM has to be restarted. Also, the

hpvmmodify command cannot be used to change any attribute of the NPIV HBA

once it is created. The vHBA must be deleted and then recreated with the new

attributes.

hpvmstatus

The hpvmstatus output now includes the NPIV HBA for guests that have it configured. All other hpvmstatus output

remains unchanged.

For example, the following status output will be shown when the command hpvmstatus –P guest1 –d is run:

# hpvmstatus -P guest1 -d
