suse 15sp1 not install for ibm power

I want to install suse 15sp1 for IBM power 9, but when installed to no operating system installed, but installed versions for ibm’s p-series, get 1 0.633gb version. But the 1.023gb and 5.17gb versions are also not good. Previously, the 5.17gb 15sp1 version was successfully installed by me, but recently I have downloaded this version on suse’s homepage.
