At one time, I broke open the UTILITY EXEC and used copies of the
commands inside it to build my own version of the utiltape. Mine started
with ICKDSF, then DDR, then the standalone FDR program. With that tape I
could initialize a volume, restore a volume (VM or MVS) and back up a
volume before going home. I used it several times at our Disaster
Recovery site.

You mentioned DDR in your OP. Is this a z/VM system?
Yes, zVM 6.1
AFAIK, a z10 can be IPL'ed from tape, ...z/OS *cannot*.
There are stand alone versions of ICKDSF (to init DASD) and DF/DSS to restore
data. The load parms are different and the activation profile will need to be
changed to ipl the stand alone's.
Check the fine manuals (ICKDSF and df/DSS Storage Admin.) for details.
The UTILITY UTILTAPE command creates a IPLable tape that will start a DDR
session. From there a system can be restored using DDR RESTORE. For my purpose
I only wanted to see if the system would IPL from the tape. If the system IPLs
from tape but not from disk, then I know where to start looking (or directing
IBM to look).
