Have acquired new customer p570 to manage and review of server shows 2 VIO lpars.

Can log into them with acct/pw supplied by customer, however the OS seems not to be AIX.

Is there a different version of AIX which runs on VIO lpars?

Not sure I understand correctly, but the VIOS is a secured version of AIX. There are special command to run in this shell to setup the VIOS env. To get to the AIX prompt, you have to run 'oem_setup_env'.

Will aix commands run in that shell after I set up that environment ?

Yes but not all AIX filesets are part of the VIO image so you might not have certain commands. You should be able to do most stuff there as padmin but root sometimes is needed.

I hope you are not thinking about making changes to the VIO LPAR since that might not be a good thing. You should think of it as sort of a HMC which is a more restricted version of RedHat Linux.

I think you chould get your hands on this Redbook. You need to understand the basics about what a VIOS, Power5 and HMC are all about.

I think this Redbbok is more Power6 oriented, but it should do the trick. You can search for Power5 Redbooks also.

VIO means your client LPARs are probably using virtual resources (network / scsi), and you absolutely need to do some reading or training to support them.

In a VIO setup, the client LPAR, VIO servers and HMC all conspire to provide IO, and it's trivial to destroy your configuration, and it's not all intuitive.

The VIO servers are running an AIX 'appliance'. It's AIX under the hood, but custom code on top. You should do everything from the shell (padmin user), and some commands look like AIX but take different options and give different output.
