Hi,

I am trying to use the following REXX to invoke DFORT to create a backup to tape (copy to disk works) with a name that is managed by the application:

/*  REXX */
PARSE ARG HLQ GEN .
HIST = HLQ||'.HIST.QAFFMQXX.GC'||GEN
BKUP = HLQ||'.BKUP.QAFFMQXX.GC'||GEN
"ALLOC FI(HIST) DA('"HIST"') NEW CATALOG REUSE  " ,
"UNIT(TAPE) RETPD(0) STORCLAS(TAPE) MGMTCLAS (TAPEDC) DATACLAS (VTSDCA)"
"ALLOC FI(BKUP) DA('"BKUP"') NEW CATALOG REUSE  " ,
"UNIT(TAPE) RETPD(0) STORCLAS(TAPE) MGMTCLAS (TAPEDC) DATACLAS (VTSDCA)"
ADDRESS LINKMVS ICEMAN

But I am receiving the following messages, and the tape files are not generated:

READY
TEMP2           TSTBT.I2AA 1627
IKJ56221I DATA SET TSTBT.I2AA.HIST.QAFFMQXX.GC1627 NOT ALLOCATED, VOLUME NOT AVAILABLE+

IRX0255E Abend in host command ICEMAN or address environment routine LINKMVS.
    10 *-* ADDRESS LINKMVS ICEMAN
       +++ RC(16) +++

END

Deeply appreciate any assistance with this matter.

The first thing I'd look at is do you have the authority to mount a tape dynamically from TSO? This is something your security administrator controls.
