IBM SG24-5360-00 manual Using Ddsr to Delete a Single Data Set

Page 60

UP (DVCUP) state, the file will be deleted unconditionally and the space returned to the RVA freespace. If the device is DOWN (DVCDN), the command will be rejected and an error message provided. Processing multivolume files is the responsibility of the operator, such that the DDSR command should be repeated for all volumes containing file extents.

NOPROMPT

Prevents decision-type messages from being issued. Some messages require an operator reply before the specified function is initiated. The specification of the NOPROMPT keyword causes the system to bypass this decision-type message and initiates the function without any additional notice.

B.2.2 Using DDSR to Delete a Single Data Set

To show the effects of using DDSR on the RVA, we deleted a single data set from the RVA, using the commands in Figure 29.

Figure 29. Console Log from Releasing the Space of One Data Set on a Volume

B.2.3 Using DDSR to Delete the Contents of a Volume

In Figure 30 on page 51, we used the DDSR option to free the entire volume with serial number PATEV3. After the space was released, all the data and the volume serial number were erased from the volume. The volume must be reinitialized to put the volume label back on the device.
