Short answer is No. I installed VIOS using Defaults, built Raid6 across 20
used the HMC to Create and Assign vSCSI drives ( 20 x 100GB ). Installed
Added the other 19 vSCSI to the ASP ans tried to install 7.1 from DVD.
TOPAS showed the hdisk virtually running at 100% Busy. I will review the
url you sent.
BTW basically spent 6+ hours on the phone with support HW, SW collecting
this and that. Total waste of the day, got no where finally wiped VIOS and
started doen the IBMi on IBMi path. After long waits for RAID6 to built and
then the vSCSI builds and adding to the ASP I am just now installing from a
Save 21 and it is running fine.

This is the only way to get reasonable performance when
using the POWER8 high function backplane or features 5913, ESA3, & EJ0L
I suspect on POWER7 you were using either its CEC high function backplane
or the feature 5903 adapters.

VIOS with3cores an d16GB Mem
Created 20 100GB vSCSI Drives for IBM i ( sees 95.5GB each )
10 each on 2 vSCSi Controllers
IBM i LIC install 8-10min ( normal is 3 to 5min )
IBM i Group1 DVD just took over 3.5hrs to install
VIOS TOPAS shows Disk at or near 100% Busy
Spent almost 3hrs on the phone with IBM and best thay could do
is have me collect snap and a perf collection and send it.
They tell that from VIOS or AIX they can't tell if the Disk
Cache is working or not. Best I can Tell from smit is it look
like the controllers are working, but I can't get IBM to help
look and tell if what I see is right , wrong or ??
Any Help or ideas would be of great in trying to diagnose this
