4. If you want to modify VOLSER ranges and assign the required static construct names to the logical volume ranges through the change logical volume function, select Logical Volumes →  Modify Logical Volumes . 

Define groups of logical volumes with the same construct names that are assigned and during insert processing. Direct them to separate volume categories so that all volumes in one LM volume category include identical constructs that are assigned. 

Host control is given by using the appropriate scratch pool. By requesting a scratch mount from a specific scratch category, the actions that are defined for the constructs that are assigned to the logical volumes in this category are run at the Rewind Unload (RUN) of the logical volume.
