volser: Specifying the volume you are deleting
Explanation: volser is a required positional parameter for which you substitute the serial number of the volume you want to delete.
Defaults: None.
Note:
- Because volser is a required positional parameter, you must specify it immediately after the command name.
- Intermittent DELVOLs of active SMS-managed volumes have little effect, because the list of volumes is obtained prior to each automatic function, and MVT and MCV records for the volumes are built at that time.
