Volume management is a facility of MPE used
to manage disk space by creating volume sets and volume classes.
The basic units of volume management are listed below:
- Volume
A volume is a disk pack.
- Volume sets
A volume set is a set of disks.
- Volume classes
A volume class is a
subset of the volumes in a volume set.
Volumes |
 |
A volume is a disk pack. A disk pack can be removable or nonremovable.
For example, in Title not available, six disks are shown connected to a system.
Every disk connected to a system is a volume.
Volume Sets |
|
A volume set is a group of volumes containing one master volume and
optional member volumes.
There are two types of volume sets available on the system,
one system volume set that is initialized when the system is installed
and nonsystem volume sets that
you create. You can create nonsystem volume sets and add
volumes to volume sets
while the system is running.
Volume Classes |
|
A volume class is a subset of the volumes within one volume set.
Volumes can belong to one volume class or
several. Volume classes can be added to the system
while the system is running.
