RE: V7R3 to V7R1 rollback plan

Geez between us has the previous release thing been made obvious?

Seriously both Larry and I have been there. Stepped on the landmines and
managed to recover. We avoid most of the landmines now but there's always
one that was not defused properly........

Once you 'Initialize System' you must initialize the disks. Note that RAID
will still be in place but if Mirroring is in use you will re-establish
that. Note that installing the LIC will take longer if it is part of a RAID
set as that initializes the load source disk. With RAID or SAN storage when
you add the disks to the ASP you will watch the numbers crawl. But at least
RAID is already there so you don't have to rebuild that.

Clearly you would not install your user data from the i 7.1 save you'll
restore from the save you did on i 7.3 with Target Release parameter set to
V7R1M0!!! Oh please do not forget that or you will hate the next couple
days!!

Here's what IBM is stating.

"A scratch install is the Install of LIC and Initialize System. The disks

will be initialized.

This is covered in App C Recovering your system in the Recovery manual....

eps.htm Step 7 is the "scratch" - Install LIC and Initialize."

I was not expecting to have to "initialize the disks" , this will add

several hours.

Also, on the restore, I was hoping to only restore IBM V7R1 files.
I was planning to restore V7R3 user data from tonight's current save.
No need to restore user data twice, correct.

Hopefully not needed, but will this be the plan.

Remember to set the previous release to V7R1.

I know there will be several object types that will not save to previous

release. Security data is one of the big ones.
