HP StoreEver MSL Tape Libraries - Manual (Page 13)

Using the Extender with the Encryption Kit
The HP StorageWorks 1/8 G2 & MSL LTO-4 Encryption Kit provides secure generation and storage
of encryption keys.
An extended library will only access the key server token in the master Library.
NOTE:
The USB port in the lower Library is not active.
The extended library must contain at least one LTO-4 tape drive to use the Encryption Kit. LTO-4 tape
drives can be in any valid drive location in the extended library.
If combining two Libraries that were both using the Encryption Kit, you can copy the keys from one
of the tokens onto the other so the token that will be used in the extended library has the keys to read
tapes from both Libraries. See the section on combining keys from multiple key server tokens in the
HP StorageWorks 1/8 G2 and MSL Encryption Kit user guide for instructions. To download the user
guide from the HP website, see
Related documentation , page 67.
If you separate an extended library that uses the Encryption Kit and will have at least one LTO-4 tape
drive in each of the Libraries, you can copy the encryption keys on the token from the extended library
to a new token so both Libraries have access to all of the keys. See the HP StorageWorks 1/8 G2
and MSL Encryption Kit user guide for instructions. To download the user guide from the HP website,
see
Related documentation , page 67.
Extended libraries and logical libraries
When the Extender is installed, the extended library is configured as a single logical library. An
extended library cannot be partitioned into multiple logical libraries.
If the Libraries are ever separated, each individual Library will become a single logical library until
reconfigured.
Installation overview
Successful installation of the Extender requires performing key steps in the order specified in Chapter
3 , page 27.
1. Obtain the latest firmware for each Library from the HP website and download it into each Library
separately.
2. Enable extended mode on each Library.
3. Power off both Libraries.
4. Position the Libraries in the rack on their own rack rails.
5. Align the two Libraries using the alignment gauge.
