IBM Support was very responsive. Gave us instructions for gathering doc. Then we could not recreate the problem with any combination of tape and console chpids on or offline. It's now working as expected. With console chpids offline, NIP goes to HMC as desired. It's possible that severely elongated IPL had nothing at all to do with console status. Sort of good news but sort of bad: this could happen again.
