Let that user own all full pack minidisks. You don't need any other statements in that user's directory except USER and MDISK for each full pack. Then link from a worker machine to perform backups. > Can I perform a restore with IPL from tape and just typing new dasd in > output command for restore or it can be done only from z/VM ? > You can restore by IPLing the tape with DDRXA program on it first, and then mounting data tapes. To create the tape with ICKDSF, DDRXA and DIRECTXA on it, do UTILITY UTILTAPE ALL or UTILITY UTILTAPE DDR for just DDR after accessing MAINT 193. Tape needs to be attached as 181 for this. You may also put the DDR program at the start of your first backup tape using MOVEFILE: 1. Mount scratch tape and attach it to your machine as 181 2. Do the following commands: REW 181 FILEDEF IN DISK IPL DDRXA S FILEDEF OUT TAP1 (RECF F LRECL 80 BLOCK 80 MOVEFILE IN OUT You may then IPL this tape in your virtual machine for practice or on a real processor.
