To recover a volume from a DFSMShsm dump with DFSMSdss, use the LIST command to find the volser of the dump tape volume that contains the dump you want to recover. See The DFSMShsm LIST command on how to use the LIST command. You can search the output data set for the volser of the volume you want to recover. Once you find the dump that you want to recover in the output data set, you will find the volser of the dump volume and the data set name of your dump. If you recover the dump to an alternate volume, DFSMSdss does not change the volser to that of the volume that the dump was created from. You need to submit JCL to use DFSMSdss. Once you have the information that you need from the output data set, you can submit a job like the following to recover your volume.
The following JCL recovers the dump data set DFHSM.DMP.DAILY.VLNX300.D01244.T072510 to volume LNX300 from dump tape A02001.
