HP Integrity VM Accelerated Virtual I/O Overview

• A4929A and A4926A 1Gbps network interface cards
Migrating LAN NICs Consisting of Only AVIO Supported Device Types
The procedure mentioned in this section can be used to migrate lan NICs to avio_lan, if the virtual
switch is exclusively configured with AVIO supported networking device types. Consult the latest HP
Integrity Virtual Machines Installation, Configuration, and Administration manual at
www.docs.hp.com for a complete list of supported AVIO backing network interfaces.
Use the hpvmmodify(1M) command to migrate lan HBA to avio_lan. For example, to migrate lan NIC
0,5 to avio_lan, use the following command line:
host# hpvmmodify -P guest1 -m network:avio_lan:0,5:vswitch:vswitchname
Note that guests need to be shut down for this command to take effect.
Migrating LAN NICs Containing AVIO Supported and Unsupported
Backing Network Interfaces
To migrate lan NICs to avio_lan in configurations where the virtual switch is configured with both
AVIO supported and unsupported backing networking interfaces, all unsupported networking
interfaces must be removed. This includes configurations where the virtual switch includes a single
NIC or an APA Link Aggregate that contains a NIC that is not supported by AVIO. Consult the latest
HP Integrity Virtual Machines Installation, Configuration, and Administration manual at
www.docs.hp.com for a list of supported AVIO backing network interfaces.
Once the lan NIC is backed exclusively with AVIO supported networking devices, you can then use
the hpvmmodify command described in the section above, Migrating LAN NICs Consisting of Only
AVIO Supported Device Types.
AVIO Storage Integration with the HP-UX 11iv3 Next
Generation Mass Storage Stack
Integrity VM 4.0 and AVIO can now take advantage of several new features in the HP-UX 11iv3 Next
Generation Mass Storage Stack:
• Enhanced Data Integrity and Protection
• Built-in native multi-pathing on the VM Host System
• Persistent DSFs
• Dynamic detection of LUN attribute changes
• Enhanced IO retry and error policies
• Enhanced storage error reporting
• Better storage tuning and diagnostic capabilities
• Support for LUNs greater than 2 TB in size
• Support for 256 TB logical volumes
Enhanced Data Integrity and Protection
Deletion or modification of a device exposed to a guest, by Integrity VM administrator, is prevented
while the device is in use by the guest. This feature helps to prevent accidental modification of a
Guest device by the Integrity VM administrator, while the device is in use by the guest.
After the Integrity VM administrator replaces the backing store of a guest device, guest access to the
device is prevented until the guest administrator validates the replacement of the backing store. This
