Re: V7R1 is SAN bootable on Power 914

Did you change the processor emulation on that partition to P8, or P7? That might explain why it boots.

Unsupported does not mean won't work, however, and a big one, it's highly likely that there is base code missing in V7R1 that is needed on P9 and that partition is soon to have a spectacular crash. That will most likely be non recoverable.

Larry and I proved long ago that unsupported does not mean it won't work. Mostly it means IBM did not test that therefore unsupported. But it's also possible that there is a software/hardware limitation that is not apparent that will cause a real problem.

I remember Larry putting some drives into an enclosure they were not meant to be in. When our contact at IBM found out he said something to the effect of, " those are not still in there are they", meaning a meltdown was about to occur. In that case a hardware limitation (cooling) would cause the problem.

For me, messing around with it is OK. The moment you put a production load on it, you've put the business and your employment at risk. That's unacceptable.

Hi,

I’ve just managed to get a V7R1 LPAR running on Power 914( Unsupported OS level for Power 914). Basically I did a Full system Flash copy from the same LPAR on a Power 8 box and booted the V7R1 LPAR on the Power 914 connected to the same Storwize and it works fine. So far, no problems reported or anything wrong.

Has anyone else noticed the same thing? Never seen a mention from IBM that this works.

Do we have someone from IBM on the list who can comment?

Regards,
Tsvetan
