Volume management tasks are performed by using three types of commands: VOLUTIL commands, system commands, and DISCUTIL commands.
Using VOLUTIL |
 |
The volume utility, VOLUTIL, provides commands for manipulating system and nonsystem volume sets. VOLUTIL resides in PUB.SYS. These commands are used to manage and maintain individual volumes, volume sets, and volume classes and to display volume content, availability, and status.

 | NOTE:
VOLUTIL must not be executed simultaneously from two or more sessions,
since many commands assume a single thread of execution on the entire
system. |

VOLUTIL can be invoked from the system prompt in two ways:
or
You can use any system command, such as DSTAT, from within VOLUTIL by first entering a colon (:), then the command.
You can execute VOLUTIL commands from the system prompt by using the INFO parameter of the RUN VOLUTIL command. To use the SHOWSET command, enter:
RUN VOLUTIL.PUB.SYS;INFO="SHOWSET PUB_SET"
|
You can exit VOLUTIL in two ways depending on how you invoked VOLUTIL.
If you invoke VOLUTIL with an ;INFO= string, as above, VOLUTIL automatically terminates after executing the specified command.
If you invoke VOLUTIL without an ;INFO= parameter, you can terminate VOLUTIL by using the VOLUTIL EXIT command. Control then returns to the system (the system prompt is displayed).
