Step 7: Format and Allocate the New Extent

Link to the minidisk that covers cylinder 0 through the end of the new CP DRCT area in read/write mode. Format the new extent and allocate it, using the CPFMTXA command. The command responds with a series of prompts to first format and then allocate the directory space.

When you finish with the format/allocate program, press Enter to return to CMS.

For example, the volume that will contain the new object directory is a 3390, linked at virtual address 100. It has a label of ESA240. The new object directory will be located on cylinders 1 through 50.

Important! Do not re-IPL until you complete Step 10: Change the allocation bit map on the old extent and re–IPL z/VM, in Enlarging the CP Object Directory (Moving It to a Different DASD Volume) in this chapter.
