Larry,
Thanks for the additional information.
There is nothing on this particular partition I need, It was never
used for anything so I do not need to restore anything after
installing 7.1
Thanks
John

So what Larry did not say was take a full system save first. Make
real sure to take the back up so it will restore to the previous
release.
You'll lose a bunch of objects that will not restore to V7R1M0.
Then do
as he instructed.
Next set up the system, with the IP, system name, etc. Basically,
setting up from scratch.
Now restore all the user libraries you need.
Be massively careful with QGPL and QUSRSYS. If you restore any system
objects from the V7R2 system to V7R1 and the file formats are
different you've just issued Barsa's MAKEAMESS command.
Happy restoring.

You have no choice here but to boot an i 7.1 LIC optical media or
tape.
Of course it needs to be sufficiently new to run on POWER8. If you
download from IBM it will be new enough. If you have a tape that
contains SAVSYS from your POWER8 you can use that.
You will get an error that says 'Cannot install LIC over the current
LIC'.
(Option 2 in on the install menu) This is because your only choice is
to completely scratch the partition and install new i 7.1 LIC since
the system is currently at a higher level LIC. Once that's installed
you will add disks, and install the operating system.

No need to ask why I need to do this, trust me I need to do this.
I have a Power 8 with 4 partitions.
All partitions are currently running 7.2
Currently in the process of updating one partition to 7.3
Want to update one partition back to 7.1 (not even sure if this is
called update? rollback? downgrade?)
At one point in the past I had CD's for 7.1 but can't find them now.
I am under SWMA so I can get 7.1 from IBM (download from IBM web
site,
can't find a way to order 7.1 CD's).
My question is: What is the easiest way for me to install 7.1 on one
of the partitions running 7.2?
Thanks in advance for any suggestions or advice
John
