HP Integrity Virtual Machines 4.2: Installation, Configuration, and Administration

[Network Interface Details]
Physical Storage type :vswitch
Guest Adaptor type :avio_lan
Backing :swlan1
Vswitch Port :5
Bus :0
Device :1
Function :0
Mac Address :2a-2e-5a-05-0a-ba
Physical Storage type :vswitch
Guest Adaptor type :avio_lan
Backing :swlan2
Vswitch port :9
Bus :0
Device :2
Function :0
Mac Address :2a-2e-5a-05-0a-bc
NOTE: The CLI accepts either avio_lan or aviolan and either avio_stor or aviostor.
For example, the following hpvmcreate commands add both an AVIO network and an AVIO
disk to the guest aviotest:
# hpvmcreate -P aviotest -O hpux -a network:aviolan::vswitch:swlan1 \
-a disk:aviostor::disk/dev/rdisk/disk1
# hpvmcreate -P aviotest -O hpux -a network:avio_lan::vswitch:swlan1 \
-a disk:avio_stor::disk/dev/rdisk/disk1
The AVIO network host driver allows simultaneous access to a vswitch from guests configured
with or without AVIO guest drivers for their virtual network interface cards (vNICs). Existing
guests continue to operate correctly and their configurations remain unchanged. Guests configured
to use a common vswitch are allowed to share VLANs that are in use by guests with or without
AVIO configured. Ports remain distinct for each running guest whether or not AVIO is in use.
AVIO networks must use a Supported Host Physical Point Attachment (PPA) network device.
For a list of supported AVIO PPAs, see the HP Integrity Virtual Machines 4.2: Release Notes. A
nonphysical vswitch, such as localnet, is not supported in this release.
AVIO increases the maximum number of devices that can be supported in a guest to 128. The
dynamic addition and deletion of AVIO devices is supported, and the following backing-store
options are supported:
• Disk (such as /dev/rdisk/disk1)
• Null (for DVD devices only)
• File
• Volume (lv)
• Tape
• Burner
• Changer
Null for non-DVD devices is not supported.
NOTE: In general, AVIO devices (that is, avio_lan, aviolan, avio_stor, or aviostor)
are configured and managed the same as VIO devices (that is lan and scsi). However, some
additional Integrity VM command options and limitations on backing devices are noted
throughout this document.
With HP-UX 11i v3, the AVIO storage guest driver can receive events asynchronously from the
VM Host for avio_stor devices whenever the underlying storage, such as lun or target, changes
state, for example, when a new lun or target is added or deleted or when the size of a lun changes.
