Re: V7R1 is SAN bootable on Power 914

Interesting conversation with IBMers that are 'In the Know' on this over the weekend. Summary.

0) It is NOT supported.
1) Yes they know it works, Currently.
2) It is NOT supported.
3) It is NOT likely to continue to work. This is because it is not tested and as firmware updates are applied to POWER9 servers one of them could very easily stop i 7.1 cold, and quite permanently.
4) It is NOT supported.
5) Given the unsupported nature and the fact that it is not tested it was stated that "We're not even sure that changing some setting via the HMC might not crash the partition."
6) It is NOT Supported.
7) "I can't imagine some one putting their, or customer data, at risk in this way!"
8) Oh, and by the way it is NOT supported.

Hi,

It's funny but I was able to also D-mode IPL an LPAR with V7R1 LIC image
and it works fine on the 914 box.

I've even successfully upgraded an LPAR from V7R1 to V7R3 directly on the
Power 914 box. It was funny because I though that the LIC load would fail
in flames.
One thing I haven't try is, to load a V7R1 LPAR from tape on the Power 914
box, but it should work since the V7R1 LIC can be booted from VIOS image.

I think I can say that V7R1 to V7R3 is a completely valid migration path
directly on Power 9.

Regards

There's always a difference between "use it for production" and "we made

I can see you dabbling with this as I have done similar in the past. I

am surprised it even boots up, that's truly unexpected. I would never put
this into production however. 'Unsupported' being the operative word here.

You will never see a mention from IBM that this works because they have

stated that it is unsupported. That is the only statement you will get from
IBM. Bet on it!
