Is there any way to recover previous generations of a GDG dataset?
While browsing a dataset, I'm not able to see few earlier generations of a dataset.
How to recover them?

Thanks.

ask Your storage support group,
- if backups are available
- about the recovery strategy for GDGs

a recovery without appropriate dsname assignment
might foul up the generation sequence

Also, if you need to get to generations that have rolled off, you may want to discuss with your storage support group changing the number of generations that are kept -- perhaps it is set too low?

Just to let u know that the dataset has a limit of 10 generations.
I also tried with checking the backup through the following command

Code:
HLIST LEV('<dataset Name>') BCDS.


And found the backup is there from the following message

DSN=MARK07.EXTRACT.SCS218.DAILY.G2179V00 BACK FREQ = *** MAX VERS=***

BDSN=DFHSM.BACK.T505019.MARK07.EXTRACT.J8262 BACKVOL=Z18357 FRVOL=MIZ491
BACKDATE=08/09/18 BACKTIME=19:50:30 CAT=YES GEN=000 VER=001 UNS/RET= NO
RACF IND=NO BACK PROF=NO

But when I tried to recover it through HRECOVER command,its failing with following message:

ARC1001I MARK07.EXTRACT.SCS218.DAILY.G2178V00 RECOVER FAILED, RC=0039,
ARC1001I (CONT.) REAS=0015
ARC1139I ERROR PROCESSING RACF PROTECTED DATA SET, RECOVERY/RECALL/DELETE
ARC1139I (CONT.) TERMINATED
RECOVER REQUEST 00189464 SENT TO DFSMSHSM

The dataset I am trying to recover is a production dataset and therefore its showing Protected in the error message.
Is there any other reason,want to know?

Thanks

I do not understand what this is asking.

To recover the file, your storage management people should be able to help.
