3. Click Create. The Cartridges tab is only generated after the library is created. The information
on the Interface Information tab is generated automatically.
NOTE: Once the library has been created, you can enable Secure Erase. See “Edit a
library” (page 20) for more information.
Guidelines on creating libraries
The table below illustrates maximum configurations for libraries and drives, but this number may
be limited if you have already created NAS shares and Catalyst stores. For more detailed device
configuration examples see the HP StoreOnce Concepts and Configuration Guidelines.

To edit library details (administrators only)
It is possible to edit some, but not all, device details after creating a library.
• Delete cartridges by reducing the number of slots on the Devices page. This will only remove
the highest-numbered empty slots. Once the Delete operation reaches a slot number that
contains a cartridge, it will not allow further reduction on the Details page, even if previous
slots are empty. To open previous slots first use the Cartridges tab to delete the cartridge from
the slot.
• Changing the cartridge size (by changing the emulation type) on this page will only change
newly-added cartridges; it does not change the size of cartridges that were already created.
• You can reduce the number of drives but, if you go to 0, the port setting will change to "No
Port".
The Number of Drives field can only be edited during library creation. After library creation,
there is a separate button to Add/Remove drives.
• You cannot change the library type to a type that has a smaller set of maximum values (e.g.
number of cartridges) than is currently set.
• You cannot enable or disable deduplication.
• Once the library is created and the correct license is applied, the Secure Erase Mode box
appears on the Device Details tab. The selection box defaults to None, meaning Secure Erase
is disabled. To enable Secure Erase, select the preferred number of Overwrite Passes (1, 3,
5, or 7). If enabled, this feature allows you to securely erase confidential data that may have
