    I've had a number of issues with Entitlement downloads and/or general installation problems.  Problems that should not be. I have several examples and recent problems have me even more concerned.  I don't want to dig through emails to try and detail every one of them.  My point it trotting this out here is two-fold.  First, to point out that simple testing is not being performed prior to sticking ISOs out there.   Secondly, to try to encourage a raising of the game.  I want to speak to three specific examples.  First, in December 2012 (yes, I'm going back for this one, but this one is so brain dead as to be boggling) I downloaded AIX 6.1 TL8 SP0 ISOs from Entitlement.  Used it to perform an update.  bos.aso was missing from that distribution and left me with a bunch of broken filesets as bos.aso was a pre-req for quite a few.  I figured my way out ot that.  A few first thoughts were along the lines of "how did this even go out the door?"

    Recently, I've had a lot of not-so-fun with VIO 2.2.3.0 distro.  As we've seen a recent flash with FC 5899 (4 port 1 gig card) , you can't create Etherchannel aggregate nor NIB (AIX 6.1 TL9 and 2.2.3.0 , by the way).  I then applied 2.2.3.1, same thing.  At the time, google lead me here:  http://www-01.ibm.com/support/docview.wss?uid=isg1IV52695  , which in turn pointed here:  http://www-01.ibm.com/support/docview.wss?uid=isg1fixinfo145795  that link talked about a fix , but wasn't pointing to anything.  A co-worker told me when he ran into this , a call to IBM and was sent "IV52695s1a.131216.epkg.Z" which fixed it.  I had no time to chase and chase so a way out for me, was to drop back to 2.2.2.2 and go to 2.2.2.4, SCA-REW 2.2.3.0.  Thoughts with this are how does a long stable driver get broken (FC 5899 has been out quite a while)?  Why wouldn't a common operation (LACP and NIB) not be tested prior to stamping a distro?  Why links that point no where?

    That same 2.2.3.0 distro caused me additional pain and delays.  While installing that same DVD on a p460 a week later (10 gbit infra, maybe 10 gbit isn't broken, client request of 2.2.3.x.. nervousness washes over me) , I was getting a 0518 on boot and a hang.  0518 in the googleples shows "mount /usr failed" - this is the same DVD that a week earlier booted (but I couldn't create a LACP group, nor NIB).  So thinking maybe I had some kind of corruption, downloaded 2.2.3.0 again, burned new DVDs,  booted ... wait for it ... same error 0518 and a hang on the p460.  Way out of the forest here was to use the trusty 2.2.2.2 and work my way to 2.2.3.x.  First thought here is:  "This freakin' 2.2.3.0 build was never booted on a p460"

    Questions: 

    - What kind of regression testing is being performed prior to stamping an ISO?  Is that test suite constantly growing?  If not, why not?

    - Are all current and common configurations re: hardware and typical implementations being tested prior to stamping an ISO?  If not, why not?

    I find this rather annoying and embarrassing to spend hours in front of clients trying to perform common operations, losing my mind wondering if I am not doing something correctly (age) and then coming to the conclusion "oh, another distro issue... whew, I thought I was losing it!"

    I would recommend you to read this: http://www14.software.ibm.com/webapp/set2/sas/f/best/aix_service_strategy.pdf

    When a new Technology Level is released, testing continues both internally and externally, and the first Service Pack is usually mandatory.
    IBM will generally mark a Technology Level recommended 90 days after its first Service Pack has been released.

     

    Also you can subscribe to IBM mailing list that report you issues encountered and their interim fix / official fixes.

     

    In my case, I usually wait until SP3 before migrating to a new TL.

    We were using AIX 6.1 TL7 SP7 and AIX 7.1 TL1 SP7 before migrating to AIX 6.1 TL8 SP3 and AIX 7.1 TL2 SP3.

    We try to keep our VIOS on a similar level than our AIX systems. We are currently using 2.2.2.4 which is equivalent to AIX 6.1 TL8 SP4.

    AIX 6.1 TL9 SP3 and AIX 7.1 TL3 SP3 is planned soon I believe but we don't see any rush to migrate yet. We might only do it somewhere between October 2014 and February 2015.

    Folks should have a strategy and I go into details about that.  But many folks want to get to a point and not touch it as long as possible - ESPECIALLY VIO.  Customer demands, etc.   And no, I would never leave anyone at SP0, that makes no sense.
