The window that is shown in Figure B-2 opens. Use the window to insert virtual volumes.  Select the  Set Constructs  option and enter the construct names. 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 feature identical constructs 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.  This section describes two host environments that enable you to use an IBM TS7700 while  running it as a guest host system under z/VM. Tip:  When z/OS is installed as a z/VM guest on a virtual machine, you must specify the  following statement in the virtual machine directory entry for the z/VM user ID under which  the z/OS guest operating system is started for the first time:  STDEVOPT LIBRARY CTL z/VM guest support Appendix B.
