Are they on tape or are they on DASD.

If on tape - Talk to your storage management people to find out the retention criteria for GDS that have expired. Usually a GDS on tape would be defined to return the tape to the scratch pool after it has expired.

If on DASD - Talk to your storage management people as the SMS / HSM set up can easily override any GDG base parameters that have been defined.

I'm not sure what you think UNCATLG means here.

Is an UNCATLG'd GDG file different from any other UNCATLG'd file?

UNCATLG means no longer in the system catalogue, but if a GDG has been bumped due to LIMIT, isn't it also deleted, and therefore no longer on it's volume's VTOC (volume table of contents)?

In which case your system's backup/recovery operation would, again, treat it like any other deleted file, and it's availability for recovery would depend on those parameters.

Let's be really clear about how we throw these terms around, and also be sure to eliminate from technical discussions irrelevant factors.

Hi,

Quote:
NOSCRATCH
- Specifies that the generation data set is not to be
removed from the VTOC of the volume on which it resides
when it is uncataloged or rolled-off.


So if the dataset is SMS managed, then I'm not sure how you managed to UNCATLG without deleting it and if the limit was reached, then the dataset would stll be available but no longer part of the GDG (STATUS--------ROLLED-OFF)

When a GDS gets rolled off it will get blatted regardless of what the GDG base definition has defined if the following is specified in the MGMTCLAS definition.
Code:
ROLLED OFF GDS ACTION ....... EXPIRE
