I just got my first Power7 machine and when hooking it up to my HMC i
found the "version mismatch" error. That particular HMC is at v7.7.3
and the fw on the p7(al740_110) requires v7.7.4 Taking into account
that my lab has machines ranging from the venerable 150 (which i'm
re-installing to attempt data rescue of a client's tapes) to this
shiny new/used (ibm remarketing) 720 (8202-E4C) i was wondering which
version of HMC code is recommended to support this wide range of
machines (I mean, of course, Power5 to Power7+, not the 150).
I also got a new HMC so i have one CR3 and one CR4 so i could have two
versions running (i know the recommended level for P5 is v7.3..5 but
v7.7.3 worked without problem with them).
To make it short. Do i install v7.7.4 or do i go all the way to
v7.7.8? In the readme i saw some info about partition info taking more
space on .8 which meant that some systems wouldn't be able to upgrade
And that managed systems managed by that version can't be later
managed by older versions (i believe that it only means that partition
info isn't backwards compatible, a full reset of the FSP should make
it work again with any supported HMC level, right?)
Thanks a lot!
PS: What does ECA 331 entail? searching for data on supported HMC
levels for that i found the advice regarding fw update on p7 and that ECA...
