Using BUILDSA without special authorization

To use the BUILDSA command, you must have the following data-set-level authorization to build the IPL-able core image for card or tape:

READ access to the input data sets used by the SYS1.SADRYLIB target library
UPDATE access to the output card or tape data sets

Without special authorization, you cannot create an IPL-able core image for DASD. Even though you may have UPDATE or ALTER access to the output SYS1.ADR.SAIPLD.Vvolser data set, you are not authorized to update cylinder 0 head 0 of the DASD volume.
