What is your MIH timeout value? Steve

First off, PARMLIB content cannot matter because we're talking about early IPL. During NIP OS doesn't even know where PARMLIB is located, let alone CONSOLxx contents. It turns out that we've seen this problem before but did not recognize it this time. After putting the console chpids back online, we got IPLed in the usual way except for this message for each of three different chpids: IOS125I CHPID xx IS EXPERIENCING MULTIPLE I/O TIMEOUTS CAUSING PROLONGED INITIALIZATION. Each of the three chpids connects a large number of Oracle/STK virtual tape units. It appears that some or all of these devices are non-responsive during IPL, causing MIH waits. So we configured the three tape chpids offline and IPLed again. This time (with console chpids back offline) we got NIP messages immediately on OpSysMsg screen. We're left with this puzzle. With console chpids online and tape chpids also online, we still got NIP messages pretty quickly. But with console chpids offline, delay was so bad we thought NIP messages were lost in outer space. So we more or less understand the tape chpid problem. We do not understand the difference in behavior with and without MCS consoles available. That is, after putting tape chpids offline, NIP messages went immediately to HMC. We have opened a PMR with IBM. . . .

I'm testing that practice for the future by configuring off the two chpids that support all MCS/NIP consoles for one LPAR. I have done that in the past when actual NIP device(s) would not work. NIP messages showed up on Operating System Messages and all was fine. Now however we are getting no NIP messages at all. Three HMCs each with an integrated 3270 at z/OS 2.1. We expected NIP messages on either the 3270 or on traditional Op Sys Msg. Nada. Has anyone with a NIPless configuration reached 2.1? Any special considerations? . . .
