AIX - stupid question 2

[MarkR800]

Can more than one version of AIX be run on the same server, i.e. if running in separate LPARs? Sounds like a very silly question, but I can't help thinking I'm seconds of giving an even sillier answer if I don't check!

Until someone asked me, I didn't occur to me that I've never come across a situation so far that has required it.

Not a stupid question. Don't know unless you ask, right?

Yes, multiple version can run on a single managed system as LPAR's. This is the whole point of LPAR'ing, to have the ability and them some.

As an example, let's say you have a p740. You can have it divvy'd up with LPAR's running different version of AIX and also different OSes all together such as VIO Servers, AIX 6.1, AIX 7.1 and Linux for PPC for example.

And if you have some old AIX 5.2 systems you cannot do without but that could do with a newer place to live then don't forget that POWER7 machines can host AIX 5.2 in AIX 7.1 WPARs:

Cheers guys! Great responses!

Previously, all the AIX boxes I've had to consider have been all the same flavour regardless of the number of LPARs they hosted, i.e. all 5.3, all 6.1, etc.

DukeSSD - thanks for the link. Had seen something about old versions running in WPARs but that just confirms it.
