Virtual Ethernet uses the system processors for all communication functions instead of offloading that load to processors on network adapter cards. Virtual Ethernet is supported on AIX 5L and Linux 2.5 and above. 

Virtual Ethernet can be used within groups of shared OR groups of dedicated processor partitions, but not both simultaneously. Virtual Ethernet comes with AIX 5L, and is supported in AIX 5.2 or AIX 5.3 partitions, but not Linux. 

Virtual Ethernet can be used in both shared and dedicated processor partitions. Virtual Ethernet can run in an AIX 5.3 or Linux 2.6 Kernel, but not AIX 5.2 partitions. Virtual Ethernet can only connect partitions within a single system. 

Virtual Ethernet uses the system processors for all communication functions instead of offloading that load to processors on network adapter cards. Virtual Ethernet can connect partitions between systems if the HMC is shared between systems.

Create two virtual adapters on the client， each one from a separate Virtual IO Server

Enable dead gateway detection on the client so that the network traffic can be rerouted

Have a spare network card on standby in the client in case the Virtual IO Server goes down

Create an etherchannel adapter on the client using one Virtual Ethernet adapter from two  separate Virtual IO Servers

Use micropartitioning for test and QA environment, and CPU pooling for the production applications 

Create standard LPARs for all test, QA, and production applications to keep all partitions separate and isolated. 

Create DLPAR partitions for all test, QA, and production applications to keep test from disturbing production environment. 

Use any Windows 2000 to graphically access the HMC

Load, install, and configure WebSM on the workstation

Telnet to the HMC using Exceed or a GUI emulator product from the workstation

An administrative VLAN with port 1808

Port 657 which must remain open to TCP/IP and UDP traffic

Network addresses are provided by DHCP services on the network

DHCP on the HMC is required to be on to communicate between LPAR and HMC

Use lquerypv to read the drive

Use lspv and look at PP Size value

Look on the outside of the drive itself

Use bootinfo to find the LTG on the drive

Run the test and dev LPARs in an uncapped mode

Activate COD resources if a failover should occur

Use DLPAR to move resources between the test and dev and the HACMP LPAR

Stop the test and dev environments， bring up new profile for HACMP failover

Use alt_disk_install
