Enabling and disabling oversubscription
Because the VLS dynamically allocates storage space as data is written to virtual media, the VLS allows
you to allocate more cartridge capacity than is physically installed. This oversubscription feature permits
configuring your system for anticipated storage growth.
By default, oversubscription is disabled.
To enable oversubscription:
1. O pen a Command View VLS session and log in as the administrator. See Opening a Command
View VLS session from Command View TL.
2. Click the System tab.
