Here is the output of the vparstatus command related to the AVIO adapters of a single vPar:
[IO Details]
hba:avio_stor:0,0,0x50014C2000000002,0x50014C2800000002:npiv:/dev/fcd0
network:avio_lan:0,1,0xb28c71e0a57b:vswitch:sitelan:portid:2
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 VSP driver allows simultaneous access to a vswitch from vPar/VMs configured
with or without AVIO vPar/VM drivers for their virtual network interface cards (vNICs). Existing
vPar/VMs continue to operate correctly, and their configurations remain unchanged. Virtual clients
configured to use a common vswitch are allowed to share VLANs that are in use by vPar/VMs
with or without AVIO configured. Ports remain distinct for each running a vPar/VM 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-UX vPars and Integrity VM V6.1 Release
Notes.
NOTE: When using AVIO networking devices for guests that are configured as Serviceguard
Packages, be sure that all Serviceguard standby lans are configured using PPA devices supported
by AVIO. Failure to do so causes network connectivity to be lost even if the standby link is up.
AVIO increases the maximum number of devices that can be supported in a vPar/VM to 256
storage devices. The dynamic addition and deletion of AVIO storage devices is supported, and
the following backing-store options are supported:
• HBA (such as /dev/fcd0) See “Configuring an NPIV HBA (vHBA)” (page 55)
• Disk (such as /dev/rdisk/disk1)
• Null (for DVD devices only)
• File
• Volume (lv)
• Tape
• Burner
• Changer
NOTE: Null for non-DVD devices is not supported.
With HP-UX 11i v3, the AVIO storage vPar/VM driver can receive events asynchronously from
the VSP 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.
The asynchronous event generation occurs in addition to any notifications issued using the SCSI
programming model, such as CHECK CONDITION on a subsequent I/O.
When the AVIO storage driver on the vPar/VM detects the events, it takes the appropriate actions,
such as discovering the new targets. For example, if new targets are added using the hpvmmodify
-a command, then the vPar/VM driver automatically detects the new device without the manual
scan. The vPar/VM automatically detects any modification of the underlying backing storage.
