A doubt :

What will happen to a generation (G0001V00) of GDG (limit 10 scrath and noempty) that was created with expdt==99000 when the G0011V00 is created.

Will the G0001V00 be scratched or will be left till life long.

Similar doubt...what will happen if the G0001V00 was created with the RETAIN parameter = 45 and the generations get created daily. Will it be retained for 45 days irrespective of the gdg limit getting exceeded?

thanks....

See 3.10 Chapter 29. Processing Generation Data Groups for the rules.

Talk to your storage people and find out how they have set up the parameters for tape retention.
