Figure 11 Library Extender installed with two MSL4048 tape libraries
The extender occupies the lower half-height drive bay of the upper library and the top half-height
drive bay of the lower library.
The upper library controls the extended library and is called the
master
library. The extended
library uses only the master library OCP, USB port, and Ethernet connection.
The lower library is controlled by the master library. The lower library OCP, USB port, and Ethernet
connection are not used by the extended library.

If you are using the encryption kit with both libraries and then install the extender, you will need
to combine the encryption keys onto a single key server token. The extended library only uses
the USB port and key server token in the master library; the USB port in the lower library is
inactive. See the encryption kit user guide for instructions on combining the encryption keys from
both key server tokens onto a single token. If the number of keys on the two tokens is greater
than 100, use the
Number of Keys to Backup
option to generate a backup file with a subset of
the keys from one of the tokens to restore to the other token.
Command View TL TapeAssure
HPE Command View TL software provides a browser-based GUI for remote management and
monitoring of most Hewlett Packard Enterprise libraries through a LAN. With Command View
TL, you can view and analyze the performance and health of the LTO-4 and later generation
tape drives and media in multiple HPE MSL2024, MSL4048, MSL8048, and MSL8096 Tape
Libraries and 1/8 G2 Tape Autoloaders at the same time. In addition, TapeAssure displays more
extensive drive and media health information than is visible in the RMI.
Command View TL software is installed on a management station. The management station can
also be used to manage HPE EML and ESL Tape Libraries. For best performance, the
