Volume Management Commands
Volume management tasks are performed by using three types of commands:
VOLUTIL commands, system commands, and DISCUTIL commands.
VOLUTIL commands are used to create volume sets, create volume
classes, and display volume status (described in
this chapter). The VOLUTIL commands are described
in chapter 5.
System commands are used to create accounts, create groups, and
mount volume sets (described in this chapter). The
system commands that refer to volume management are
described in chapter 5.
DISCUTIL commands are used to recover data from damaged disks
(described in chapter 5).
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.
Starting VOLUTIL.
VOLUTIL can be invoked from the system prompt in two ways:
RUN VOLUTIL.PUB.SYS
or
VOLUTIL
You can use any system command, such as DSTAT, from within VOLUTIL by
first entering a colon (:), then the command.
volutil: :DSTAT
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"
Exiting VOLUTIL.
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).
