HP vPars and Integrity Virtual Machines V6.1 Administrator Guide

# hpvmmodify -P vpar -m lan:dio:b,d,macAddr:hwpath:new-hwpath
◦ Modify the MAC address:
# hpvmmodify -P vpar -m lan:dio:b,d,new-macAddr:hwpath:hwpath
• The hpvmstatus command — allows you to:
See vPar and VM configurations. The direct I/O network functions are included in the
#NETs count.
# hpvmstatus
◦
◦ See specific vPar or VM I/O details:
# hpvmstatus -P vm -d
NOTE: There are no new switches specific to direct I/O for the hpvmstatus command.
• The hpvmstart command — allows you to:
◦ Start a vPar or VM with direct I/O:
# hpvmstart -P vm
NOTE: Two vPars or two VMs cannot start if they are using the same direct I/O function.
Also, two vPars or two VMs cannot start if they are using the same device level assignment
(DLA) device.
• The hpvmstop command — allows you to:
◦ Stop a vPar or VM that is using direct I/O:
# hpvmstop -P vpar
NOTE: There are no new switches specific to direct I/O for the hpvmstart or
hpvmstop commands.
To map direct I/O devices between the VSP and the vPars or VMs:
• From the VSP:
# hpvmdevinfo -P vm
• From the vPar or VM:
# hpvmdevinfo
To restrict DIO-capable devices to the VSP, use the following command:
hpvmdevmgmt -a rdev:hwpath
NOTE: Note: if the hwpath is for a DLA function, all functions will be added.
The hwpath must be assigned to the VSP in order for it to be restricted for VSP use. If the hwpath
is already in use by a vPar/VMt, the -a add will fail.
HP recommends that administrators manually restrict all functions that are used by the VSP for VSP
networking, because that is not currently done automatically. HP also recommends that administrators
manually restrict all functions that are assigned to vPars and VMs for use with AVIO, to avoid
conflicts at vPar/VM boot time, because those functions will not appear to be in use until the vPars
and VMs are booted.
To view the NICs that support DIO on a VSP, use the command: vparhwmgmt -l -p dio (or
hpvmhwmgmt -l -p dio ), which shows the DIO supported cards and the assignment level
they support (device or function):
# vparhwmgmt -l -p dio
