Sarip, if the volume the dataset was on was controlled by DFSMS, then you can try either the RECOVER or RESTORE command in ISMF.
HRECOVER recovers a backup version of an individual cataloged data set from a DFSMShsm-managed volume. When you enter HRECOVER, ISMF displays the HRECOVER Entry Panel. The entry panel is primed with the name of the data set you want to recover. On the entry panel, you can specify the generation number or date of the backup version you want to recover as well as the serial number of the target volume. You can also choose to rename the data set as it is recovered or to replace the existing data set with the backup version.
HRECOVER is performed in the foreground by DFSMShsm. You can wait for the data set to be recovered before you return to the list panel. If you choose to wait for completion, the HRECOVER Entry Panel is displayed until the command has been performed. Otherwise, you return to the list immediately.
RESTORE allows you to restore data sets dumped by DFSMSdss to a DASD volume. RESTORE is performed in the background.
See your installation’s MVS Systems Programmer to find out if the volume was DFSMS controlled.
Good luck. MzVee
