Initializing the residence volume

When you are generating stand-alone dump for residence on a direct access volume using the stage-two JCL, a SYS1.PAGEDUMP.Vvolser data set containing the stand-alone dump program is created, loaded, and IPL text is placed on the volume. If the volume already contains a SYS1.PAGEDUMP.Vvolser data set, the stage-two job fails. While the stage-two job is running, the mount attribute of the volume must be PRIVATE.

Physical output from the assembly part of the initialization step is a listing for the stand-alone dump common communication table (CCT) and devices and dump options (DDO) control blocks that contain information specified at generation time. The remainder of the output consists of informational, error, and action messages from both stand-alone dump and, when the residence volume is direct access, the device utility ICKDSF.

When generating the stand-alone dump program from a Magnetic Tape Subsystem, be aware of which tape format you use or you might not be able to IPL the program. Specifically, IPL processing will end abnormally if you:

Generate stand-alone dump on a 3490E Magnetic Tape Subsystem and use a tape subsystem other than a 3490E for the IPL.
Generate stand-alone dump on a tape subsystem other than a 3490E and use a 3490E Magnetic Tape Subsystem for the IPL.
