Tandberg StorageLibrary T128 User’s Guide 13
Details about licensable features include:
• License keys can be used only once and cannot be transferred to another library.
• License keys do not expire.
• A given license key can encode several features.
• License keys are absolute values that can only increase licensed features.
For example, if you have a 5U control module with 9U expansion module (128 slot) configuration,
and you want to increase the storage capacity of the library from the 82 slots that you activated at
the time of purchase up to the maximum 128 slots for the configuration, you will need a COD license
key with 128 slots licensed.
• Once you install a license key, you cannot remove it without re-initializing the system. However,
entering a new license key does not require re-initializing the library. See
Shutting Down or
Restarting the Library on page 67 for more information on re-initializing the library
• The number of licensed slots can never decrease.
• The license key is associated with the serial number of the 5U control module. If you must replace
your control module for some reason, you will need to request a replacement license key from
Tandberg Data.
• The library control blade (LCB) compact flash card contains information about your library
configuration. If you must replace your LCB flash card, you will need to request a replacement
license key from Tandberg Data.
Capacity-On-Demand (COD)
The library ships with a minimum of 36 active slots. At any time, the COD feature allows you to enable the
inactive storage slots within a library by using COD license keys. COD license keys are available in 46-slot
increments. For information on obtaining a COD license key, see
Obtaining a Capacity-On-Demand License
Key on page 44.
To see your library’s current configuration and slot availability, you can open the Library Configuration
report from the Reports menu of the web client interface. Table 2 on page 14 shows the number of
licensable slots that are available in the different library configurations.
Once you receive the firmware license key, enter the key via the operator panel of the library. When the
license key is entered, the total number of available slots in the library increases. An expansion module may
be required, depending on your configuration. See
Applying License Keys on page 43 for more information
on activating a licensed feature.
CAUTION
While you are entering a license key, backup operations may be
interrupted.
Note
The numbers of licensable slots listed in Table 2 are adjusted for the unusable
slots in each configuration. The number of physical slots in the 5U and 14U
configurations is always ten more than the number of licensable slots.
