Re: Install (or rollback) to previous version of OS

[DrFranken <midrange@xxxxxxxxxxxx>]

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.
