RE: HMC code update from the grave

Another great example of the need to keep current. Now, a simple upgrade turns into multiple upgrades keeping both sides compatible.

Don't forget, after you upgrade to 6.1.2, there are a bunch of additional fixes that have to be put on before you do the V7 upgrade. Make sure you read the "read-me Notes".

Subject: Re: HMC code update from the grave

ohhh, i knew i was asking for a reason.
n°1 is the culprit that i have to install v6r1.2 before v7, v7 doesnt like any fw below 240_382 or so, and v5 doesnt like anything higher than it already has, so i have to use v6r1 to update the fw and only then can i go to v7r3.5M4

I'll pencil n° 2 in big red letters in my procedure. It should be the default password (i have yet to see a client that changes the hmc/asmi password, many dont even change the DST ones).
In any case, i may end up re-partitioning the machine, since they have
2 partitions but in the time i've been in charge of maintenance, they havent even started the second one.

Best regards and thanks!

Two things to keep in mind:

1) Watch for the relationship between the firmware and HMC. That is,
don't update the HMC too far all at once so that you loose connection
to the FSP.

-and more importantly-

2) Make sure you have the HMC access password. If you completely
reload the HMC then it will 're-introduce itself' to the FSP and the
FSP will require that password.  (Yes you can reset the FSP with the
magical switches but then it kinda forgets everything it knows.)

I had to make the same upgrade a while back.  I hired an expert to do it.  He ended up wiping the HMC and discarding the backup data.  He reloaded the one server with one partition back from the service processor with no loss of production data.  Your plan sounds valid and about what we did over a fuzzy and busy year ago.
