HP-UX vPars and Integrity VM V6.3 Administrator Guide

conflicts at vPar or VM guest boot time, because those functions will not appear to be in use until
the vPars and VM guests are booted.
Use hpvmhwmgmt or vparhwmgmt command to view the DIO supported cards on a VSP and also
the assignment level the NICs support (device or function):
# vparhwmgmt -l -p dio

Use the hpvmhwmgmt -p dio –a path command to assign the card or function to the DIO
pool. For DLA cards, you can use the path of any port on the card. All functions of the card are
assigned to the DIO pool. After the function or device is added to the DIO pool, the hpvmhwmgmt
command shows the owner as hpvm and not host.
NOTE: If you use the –L label option when adding a DLA card to the DIO pool, only the
function (path) that was specified in the command line will be labeled, other ports of the DLA card
must be labeled individually.
# hpvmhwmgmt -p dio -a 0/0/0/4/0/0/1 -L DLA1
# hpvmhwmgmt -l -p dio

When a DIO device is added to the DIO pool, ioscan shows the device is claimed by the hpvmdio

You cannot add a function to the pool if it is in use by the VSP:
