Issue:
A generation data set, which already exists in DEFERRED status can't be restored with PREALLOCY.
The RESTORE fails with

ADSUT176 2546 CATALOG RETURN CODE IS 8 - REASON CODE IS 42
ADSUT176 NO RECORD FOUND IN AN ICF CATALOG
ADSDM069 2187 DSNAME = data.set.G0054V00 WAS NOT RESTORED DUE TO PREVIOUS ERRORS DURING DASD ALLOCATION
ADSDM069 3706 DEFAULT POOL = TEST IS NOW BEING PROCESSED.
ADSDM197*0007 data.set.G0054V00 NOT ALLOCATED POOL TEST NOT DEFINED
ADSDM069 2187 DSNAME = data.set.G0054V00 WAS NOT RESTORED DUE TO PREVIOUS ERRORS DURING DASD ALLOCATION
ADSDM069 4177 DATA SET INFORMATION => LRECL= 180 BLKSZ= 27,900 DSORG=PS RECFM=FB TOTAL TRACKS= 15
ADSDM077*0450 data.set.G0054V00 WAS NOT RESTORED DUE TO PREVIOUS ERROR(S)

and the data set is deleted. The next RESTORE will work, since the data set no longer exists.
