AIX Down Under
If you're new to AIX, you may not know that AIX 5.3 was officially called AIX 5L. And it's no longer officially supported, unless you have paid for Extended Support or are running versioned WPARs.
"5L" didn't refer to a particular version of AIX 5. The "5L" applied to AIX 5.0, 5.1, 5.2 and 5.3. AIX 5L for Power version 5.0 was first announced back in October 2000. On the technology side:
Why am I mentioning all of this? Because I saw a web site today with a package which includes support for AIX. AIX 5L, that is. And that was the last version of AIX mentioned.
Now I was looking to install this package on a Power7 system that ran AIX 7.1. Would it work? Well, there is the IBM binary compatibility guarantee, and AIX is famously backward compatible. But what about new features? Would the package be able to take advantage of the Virtual I/O Server, Active Memory Sharing, virtual ethernet or NPIV?
Admittedly, for some software, you might be happy if it is going to work without crashing, but with other software, such as for monitoring, management or job scheduling, you'll probably want something which is integrated deeply into the Power Systems architecture. For example, you'd probably want software which could talk to the Hardware Management Console (HMC), and the Power System's hypervisor.
If you're advertising that your software will work on AIX 5L, and make no reference to any developments in AIX since 6.1 came out, for example, then your software is going to look a little dated.
Maybe it's time to update your web site, or go back to your Playstation 2.

There are lots of good reasons for having spare disk for rootvg, as I looked at in the post make way for rootvg. With virtual disks you can resize your volume group on the fly:
Note: this is supported for rootvg and concurrent vgs from AIX 6.1 TL 4. See IBM technote IZ80021 http://bit.ly/cmHjmy
Resizing the rootvg disk
I tried to increase rootvg on an LPAR running AIX 5.3 TL 11 and hit the following error:
Looks like the volume group needed to be varied off and varied on again. For rootvg, that means a reboot.
No reboot on AIX 6.1
In AIX 6.1 (from TL 4 - use oslevel -s to check your AIX level), you can increase rootvg on the fly.
Sounds like yet another reason to migrate to AIX 6.1.

Quick migration to AIX 6.1
Yesterday I used the Virtual Media Library to do a migration of an LPAR from AIX 5.3 TL 11 to AIX 6.1. The migration took under 25 minutes. This included:
I then installed the latest service pack, once again via the VM Library. This took just over 2 minutes. I had downloaded the service pack from the IBM Support Portal.
Fast and painless migrations
All up, the migration was about 25 minutes, including rebooting time. Of course, this doesn't include the preparation time downloading the software or time to take a backup.
This is just a few minutes faster than the migration to AIX 7.1 which I did on a different LPAR last week, but both of them were really very fast and painless. That's how it should be.
