Gigabytes, or Terabytes from the drop-down list. This sets a maximum size for the 
virtual tapes in the pool.
Note If you select the Cartridge Size unlimited checkbox, VTS can create virtual 
tapes up to 2TB. However, virtual tape sizes may still be limited due to file-system 
constraints. 
7. If you want to set a limit to how long the virtual tapes in the pool are stored, deselect the 
Retention unlimited checkbox and specify a value in the field. Then, select minutes, 
hours, days, weeks, or years from the drop-down list. This retention period governs 
when the virtual tape can be erased to reclaim space in a vault.
8. Select the Autoloading checkbox to enable the pool to automatically load and unload 
virtual tapes as they are used, from the first to the last virtual tape in the pool. 
Note To manually disable autoloading, select a virtual tape drive (host device) on the 
Virtual Media - Operation page and click Unmount.
9. If you select Autoloading, you can then select the Recycle checkbox, which enables the 
pool to autoload indefinitely without user intervention. A pool can automatically cycle 
back to the first virtual tape in the autoloader when the last virtual tape is unloaded. This 
feature provides continuous and unattended operation for almost any application. If this 
checkbox is not selected, the virtual tape drive is unmounted once it reaches the last 
virtual tape in the pool.
10. If the SecureVTS feature is enabled, you can select the Encrypted checkbox to encrypt 
all cartridges that are added to the pool. See 
Using SecureVTS on page 81 for more 
information about this feature.
11. Click APPLY.
