I do have the dimmest memory of IPLing a new LPAR that did not yet have a SYS&SYSCLONE LOGREC. (Disclaimer: all my memories are dim.) Perhaps the system prompted for a usable LOGREC data set, or at least the volser of the named guy. But I think we've established that you will not IPL without some LOGREC data set available.
Note that this is not true for other logstream recording mechanisms like SMF and OPERLOG. A system will limp along with no usable MANx data set; also with no functioning OPERLOG. In fact this happens to us every time we bring up our DR systems for the first time--without any defined logstreams. You can create a logstream only on the exploiting system. So we IPL, then run the log stream creation jobs for SMF, OPERLOG, and RRS. . .
