In the last few days I've had lots of fun with migrations to AIX 6 and 7. And when I say "fun", I don't mean it in its usual technical sense within IT (insurmountable problems, unrelenting stress, obscure workarounds and chronic sleep deprivation).
I mean "fun" according to its (almost obsolete) usage:
Over the last few days, I have
All of the upgrades went smoothly, with no challenges or what IT people mean when they say "fun".
Making a fresh start
My last feather in the AIX 7 cap was to do a "New and complete overwrite" installation of AIX 7.1. You might do this instead of migrating your system from an earlier release. If your LPARs are full of inconsistencies and undocumented workarounds, maybe it's better to build a system from scratch.
If you want to (or need to) make a fresh start, so that you can clean out the soul of your system from the sins of the past, it's good to know that AIX 7.1 is fully binary compatible with AIX 6 and AIX 5. Building a shiny new LPAR is especially useful if you decide to create an AIX Standard Operating Environment (SOE) LPAR.
Half an hour to AIX 7.1
The fresh install of AIX 7.1 took around 25 minutes, using the VIO Server Virtual Media Library, which is how I did the other AIX migrations. The new and complete overwrite installed 591 filesets as the main course, and then another 4 for dessert.
Here you see the creation of the boot image at the end:
The reboot time took around 3 minutes. I've yet to install the mandatory AIX 7.1 service pack but I expect it will be all over red rover in about 5 minutes. It can be downloaded from the IBM Fix Central web site.
As with the other installations, the VM Library was running off internal SAS disk allocated to the VIO Server. The target LPAR boots from SAN, using vscsi disk which is passing through two VIO servers using MPIO.
AIX 7.1 is fun
I'm enjoying these AIX installations and migrations but they were so straightforward that it's getting a little quiet around here.
I wonder when AIX 8 will be ready.
