Generally, you can reference any existing uncataloged dataset by specifing the volser of the device on which the dataset resides.

UNIT=CART,
VOL=SER=(923871,924196,924619,926242,926307,926277)

Hello,

Are these dasd or tape/cart datasets?

If they are tapes that have not been re-used as scratch tapes, you can read them by specifying the volser(s) for the file(s).

If they are dasd, you need to see if there is a backup of them available. If the backups do not exist, the files are gone (unless by some magic, the space hasn't been re-used and there is some tool to "re-find" them - though not likely).

Hi,

Try using HRECOVER in Option 6 of ISPF menu to recover the lost generations.

Howdy,

Use HRECOVER in option 6 in ISPF by giving the lost GDG version number and give newname ('your file name').

Try this
