That's the correct process. The key point is to ensure that the entire disk is CP-formatted with the CPVOL FORMAT command in ICKDSF (CPFMTXA calls DSF under the covers) before you let CP try to page to it. The cyl 0 vs 1 discussion is just a safety measure; CP is usually smart enough not to shoot itself in the head by paging onto the volume label & allocation bitmap that tells it where it paged stuff...8-)
