Overview of the Conversational Monitor System (CMS)
Just as you can interact with Linux or UNIX
can interact with z/VM through CMS. Like a shell, you can use CMS to edit files,
run EXECs (script-like executable files) or programs, modify the virtual machine
environment, or modify z/VM itself. CMS is to z/VM as a shell is to Linux or
UNIX.
Minidisks and the CMS access mode
CMS, like other operating systems running in a virtual machine, can access
minidisks to store and retrieve files. For CMS, each minidisk has an access mode
environment as well as run some REXX
set up Linux. After changing the environment, you can load Linux into the
virtual machine.

Is the disk type of the real disk; typically 3390.
start_cyl
Is the real disk starting location of the first cylinder of the minidisk.

Is the minidisk size in cylinders.
vol_label
Is the volume label of the real disk.
