Hi,

I created a PDS in WORKDA, work library. It got deleted after a few days. Please let me know if there is a way to recover the deleted dataset?

Please tell me the TSo command if avaiable

You can recover it only if a backup is available!
since we know absolutely nothing about Your environment we cannot tell
ask Your peers or Your storage support group

Only if your site uses ye olde classic DASD subsystems, and even then probably not.
Most modern RAID6 subsytems do not closely map volumes to the internal arrays anymore.

So unless you have taken a backup or two it will unfortunately be a case of bye bye dataset.

First you need to know if the data sets are under HSM control - if so, the HRECOVER command will work for you. If they are not, then you must restore from a back up. There may be a system back up taken that could be used, or an application back up. If there was no back up made, and the data set is not under HSM control, then you cannot recover the deleted data set.

Anuj, Unfortunately the fact that HSM may be installed and processing does not guarantee that everything is backed up. That depends on how the SMS subsystem is defined.

If the user issues from option 6

HRECOVER 'data_set_name'

He will find out fast if any HSM backup exists or not.
