Installing the VIO Server using the HMC

Before Installing the VIO server code, you need to know the metwork configuration data for the server

1. Insert the VIO server CD or DVD into HMC DVD drive
2. Enter installios on the HMC command Line Interface to invoke the installios wizard where you can install the VIO server code by answering the prompts
3. Alternatively, the command listed below will install the code without the wizard prompts. The -n option tells the the installation not to configure the network interface. You will do that manually.
4. When the installation complete, open a terminal window to the partition on the HMC
5. Log in as padmin user and choose a new password.
6. Before using VIO server, you must accepts the Licence
7. To view Licence, Enter licence -ls at the command line
8. To accept the licence, Enter licence -accept
