Hi Abhishek,

From subject line,

Hi,

are you saying the dataset is migrated ?

if so HRECALL will do it.

If the dataset does not exist at all, you will need to use HRECOVER as long as the dataset has been backed up by HSM or you will need to restore from whatever medium it was backed up to.

If no back up exists, then I'm afraid unless you can rebuild the file, the GDG is lost.

Hi Gnanas,

I mean..I need it on DASD to view that version of GDG.Basically its making that version available to be viewed which is possibly on Tape right now.

Thaks,
Abhishek

Again, if that generation is migrated to TAPE, please use HRECALL to move it to DASD.

If that generation was created on TAPE, please use SORT or IEBGENER to copy it to DASD.

Hi All,

Sorry for the delay in respose....Actually HRECALL and HRECOVER are not working for me.

Again, I say.

HRECALL is for recalling migrated datasets.
HRECOVER is for recovering dataset from backup version.

Please clarify your things here.

Hi,

My requirement is to recover a GDG version which is in Tape to DASD.
So,I tried using HRECALL, but it doesn't work....

Thanks,
Abhishek

Hi Abhishek,

Here, HRECOVER won't work. It's for recovering deleted datasets.

Please use SORT or IEBGENER or any other copy utility for the same.

Note that if a dataset is migrated to TAPE, you can see its volume as MIGRAT/MIGRAT1. This time only, you can use HRECALL.

I hope everything is clear now

GDG management is a murky and painful issue
work closely with Your storage support to avoid troubles

RECALLING does not have any issues , the GDG generations are cataloged considered as existing
and the recall will NOT clobber the generation sequence and LIMIT

RECOVERING is a completely different beast, a careless RECOVERY will certainly disrupt the generation sequence

recover with a rename and evaluate with attention where the recovered dataset should be place in the generation sequence

- I have seen big men cry for a careless HRECOVER

Hi,

my experience with HRECOVER with GDG's is that if does not already reside on DASD, the HRECOVER version will come back as
ARC0770I SMS GDS XXXX.IOA.LOG.BACKUP.G6025V00 RECOVERED AS DEFERRED GDS but personally I would go along with Enrico and recover with a rename.
