>Isn't "fall back to the CP" because one would typically want one's work to run *somewhere* even if a zIIP were not available but perhaps a CP was?
If you meant no zIIPs are available to the LPAR (not configured or the CEC does not have some), then there is no fall-back. Work units get queue on CP work queues initially; the zIIP work queue is not being used. At least this is how I understand it. If you meant no free zIIP capacity is available, then part of the decision might have been that initially you could have only half as many zIIPs as you had CPs. -- Peter Hunkeler ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
