Here is an example of using DSS to create a FlashCopy consistent clone. Note
that for active data, this is considered a 'crash consistent' copy because the
consistency is at a physical i/o level, not a logical transaction level.

Thank you for the hint.
Actually I saw the example, but I don't understand it.
|//SYSIN COPY FULL INDYNAM(SRC101) OUTDYNAM(TGT101) ADMIN DUMPCOND
FCFREEZE PARALLEL COPY FULL INDYNAM(SRC102) OUTDYNAM(TGT102) ADMIN
DUMPCOND FCFREEZE COPY FULL INDYNAM(SRC203) OUTDYNAM(TGT203) ADMIN
DUMPCOND FCFREEZE SERIAL CGCREATED FCCGVFY(SRC101) ACCVOL(SRC101,SRC203) /*|
I don't understand why the PARALLEL is not the first command. I think
all three COPY command should be performed in parallel.
I guess FCFREEZE means "wait until..."
Then SERIAL - that's OK as far as I understand.
Then CGCREATED - I understand it as "start a copy of consistency group".
However I don't see SRC102 in the command. Is it a typo in ACCVOL()?
Regards
