1. Run IOS commands as root

According to IBM you should never work as root on VIO servers. However, if you login as user padmin and type

 oem_setup_env

you get the root credentials (without even been asked for a password).

By default the ioscli commands are not available for the root user. All ioscli commands are in fact calls of /usr/ios/cli/ioscli with the command as argument. You see this if you list the aliases of the padmin user.

Knowing this you can use all ioscli commands as user root by appending /usr/ios/cli/ioscli. Instead of »lsmap -all« you would type

 root@vios# /usr/ios/cli/ioscli lsmap -all

If you set an alias

 alias i=/usr/ios/cli/ioscli

you could even type

 root@vios# i lsmap -all

1. Introduction

IOS version 1.5 introduced virtual optical drives. This small article shows how to make use of this feature when installing an LPAR. This might be handy if you want to upgrade a NIM server without the need to spend a day in the datacenter or when there is no CD drive available to assign to an LPAR.

2. Getting the ISO Image

Before we can start creating our virtual optical device we need an ISO image.

Sometimes ISO images can be found on the web - in this case you can simply download the image and copy it to some space on your VIO server. But we want to install from an AIX installation DVD - the AIX 6.1 installation ISO of course cannot be found on the web - so we have to create an ISO image from our physical AIX installation CD or DVD.

There are multiple ways to create ISO images. The easiest way to create an ISO image from the AIX Installation CD or DVD is to insert it in the DVD drive of a Linux box and just dump the CD/DVD to a file:
