Re: Power 6 Host/Guest Question



fixed

For 7.1 you're good. Nothing in there is supported by only 6.1.

As ROb says 7.2 for sure will find stuff that's not supported. His example is perfect as I put up a 7.2 partition at COMMON the day it went GA. That sever is Power6 and has an 0595 drawer with 2844 and 5761 Fiber. Without thinking (in my defense I was sick all the way through COMMON) I moved that to the i 7.2 partition and it did, well, nothing. Nothing at all. After a little more cold medication I then moved the PCIe 5774 fiber card in the system unit to the partition and there it was, good to go.

In my situation no 7.2 yet, but Rob thanks for that information. Is there
a command you can run on POWER6 systems that would roadmap what will not
work if you load 7.2 or is it a MEMO to users document and then print off
your rack config to match it up against. For my situation, I need 6.1 host
with (1) 7.1 guest.

I did host some guest lpar's of 7.2 underneath a 7.1 host lpar. Yes it
still generated some warning messages about the underlying hardware having
some cabling loops that it didn't like but it worked. Best make darn sure
that that whatever hardware you do need by the 7.2 lpar is carefully
thought out. Like, you're not even thinking about using a scsi tape,
right? And if it's fiber it's on an IOPless controller on the main unit,
right? I'll be honest, the ancient hardware I had, and the draconian
restrictions of 7.2, put a serious crimp in my style of having all lpars
on the latest release within 3 months of G/A.

There is a bunch of hardware that IBM i 7.2 will not recognize. Your
Power6 machine likely has some of that hardware. As a result you most
likely cannot upgrade your HOST partition to IBM i 7.2. You CAN have i
7.2 as a guest along with i 7.1 and i 6.1 guest partitions.

Is there a cheat sheet document that would show an overview of what is
allowed. Can you mix and match, I have a HOST LPAR at 6.1 with 6.1

Lpars, can one of the Guest Lpars be 7.1
