To copy LOADxx members to a backup volume, use either DFDSS (for SMS-managed volumes) or IEBCOPY. To ensure that the system will associate the copied LOADxx member with the proper IODF on a SYSn.IPLPARM volume, do not specify the IODF prefix in the LOADxx member. The system then will default the prefix of the IODF data set to the prefix of the SYSn.IPLPARM data set that contains the LOADxx member.
