Thanks, and yes, It does fail without sys1.logrec.
I can't believe the system can't come up without LOGREC. I would think it should issue messages but at least let you IPL. Once you're up you can allocate a new one. Maybe Z/os could even dynamically allocate one and just keep going. From what I can gather so far about Logstreams, it just holds a bunch of different logs like Operlog, LOGREC, etc. but the data is still in it's original form as if it were read directly from the original data set.

I checked our MSTJCLxx, but LOGREC is not named there. It is however named in IEASYSxx, where we have coded LOGREC=SYS1.LOGREC.$SYS&SYSCLONE ever since we moved to sysplex in the mid-90s. I cannot recall trying to IPL without LOGREC, but I imagine it would fail. There are good reasons for moving to logstream, but the ability to IPL is not one of them. . .

Will the logstream still allow me to IPL eve if SYS1.LOGREC is gone?
