PowerHA for AIX

Originally posted by: garyBennett

Watched Shawn's tube about a NDU to PowerHA 7.2 while on AIX 7.1.4.  Although his title said AIX 7.1.3, his example was actually on 7.1.4.  The AIX/PowerHA support matrix suggests that AIX 7.1.3.5 should work fine for Power 7.2.  Just wanted to confirm the NDU to 7.2 would work for 7.1.3.5.  (currently at 7.1.3.4 and don't feel comfortable upgrading to 7.1.4.0, yet--- too new).

TIA for recommendations.

Hi Gary

If your  present cluster is in PHA version 7.1.3 yes you can perform NDU to PHA 7.2 with AIX level 7.1.3 or later

Please refer this link , I hope this might confirm your doubts.

Actually despite previous reply and what the pub says, you can NOT NDU to PowerHA 7.2 with only "AIX level 7.1.3 or later". The key thing is, you must already be at a level of AIX that supports the level of PowerHA you are trying to NDU to, so yes AIX 7.1.3 SP5 would be a bare min to get there. These two replies show the difference between experience and just rattling off what the pub says.

Btw, my title says "PowerHA for AIX v7.1.3" refers to the PowerHA level, not the AIX level. Just like the upgrade did NOT go to AIX 7.2, but to PowerHA for AIX v7.2. It's a common confusion point because PowerHA and AIX levels are similar.

Though the NDU worked, there were other issues with 7.1.4.0 I encountered so as your wisdom shows, it was a good idea to skip it.
