More precisely, allocations from the Cylinder-managed space on an EAV are rounded up to the next multiple of 21 cylinders. Allocations from the track-managed space area up to cylinder 65520 continue to be allocated as before. The boundary between them is cylinder 65520. I don't know if there are any restrictions for using an EAV for an IPL volume. -- Tom Marchant ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
