Re: PowerVM - running AIX and IBMi

I suspect that the AIX migration from POWER 6 to POWER 10 will not be a
simple migration.
That's a pretty big jump, you might need to update AIX versions first..

According to this doc https://www.ibm.com/downloads/cas/O1YP5RYZ
AIX 7.3 supports POWER 10 nativity
While 7.2 supports it in "POWER 9" mode ¯\_(ツ)_/¯
and 7.1 supports it in "POWER 8" mode ¯\_(ツ)_/¯

For that matter what version of IBM i are you running on your POWER 8?
If not 7.3 or higher ...then that also won't be "easy".
An upgrade to 7.4 first should make things easier.

That’s a no brainer. AIX and IBM i happily coexist on the same platform.
AIX is just another partition. VIOS will virtualize AIX and IBM i together
both storage and Ethernet. Just requires doing a little work on the HMC
to create the partition, and virtual storage devices, add the host on the
SAN, create LUNs and you’re done. You can do that on your P8 now if you
wish. As long as you have sufficient CPU/Memory/Storage, 90% of what you
need is already there. Add those LUNS to your replication scheme, and
that’s done too, although you don’t need to if you don’t want to.

Need to upgrade our primary server running iBMi and probably will go to

Power 10 S1022.
Currently running a Power 8 using IBM Storwize V5030 SANS.

I was asked by another part of the business who run AIX on Power 6, if we
are getting new kit, could we host them also to save buying two new

servers

(production and DR). Looking around it seems we could use PowerVM and

run

both AIX and IBMi LPARs and share the fibre channel cards to the SAN (SAN
has enough storage).

There is a 900 page Red Book on PowerVM but that's a difficult read :-(
Hoping to know if any people on the mailing list are doing this and what
their experiences are. Thanks
