Bill,
A couple questions back. Do you have DFDSS/DFSMS-dss/ADRDSSU? Are you
licensed on your DS8K for flashcopy? Is the target disk volume involved in a
PPRC replication scheme (global mirror or the like) with a secondary array? If
you answer yes to the first 2 questions and no to the third, this is an example
that works for us.
//STEP005 EXEC PGM=ADRDSSU,REGION=0M
//SYSPRINT DD SYSOUT=*
//SYSIN DD *
COPY DATASET( -
INCLUDE( -
PVS.CL.AGENT - <<<< source dataset - is on
a replicated volume but source doesn't matter to FC
)) -
CANCELERROR -
CATALOG -
RENAMEUNCONDITIONAL( -
(PVS.CL.AGENT, -
PVS.C6.AGENT.REX)) - <<<<< my target is on a disk not
being replicated to our secondary site
SPHERE -
TOL(ENQF) -
TGTALLOC(SOURCE) -
FR(REQ) - <<<<<<< I'm telling DFDSS
it has to use flashcopy
WAIT(2,2)
And here's the output of the job.

HIGHEST RETURN CODE IS 0004 FROM:
TASK 001
The reason I asked about the disk replication is that out of the box, flashcopy
is prohibited to send the target dataset to a replicated volume. I believe
there some hoops that can be jumped through to make this happen (at least I
seem to remember reading about this at some point) but normally that's
prohibited. If everything is set up properly, you don't need the FR(REQ) or
FR(anything) and DFDSS will use FC when it can and if it can't it'll do the
copy in the traditional way.

Can anyone provide an example on how to use flashcopy to copy, or backup, an
individual dataset?
thanks
Bill
