NOTE:
If you are running Command View TL version 2.0 or later, you can install Command View TL on multiple
servers (management stations) and manage the library with more than one management station at the
same time. If you are running an earlier version of Command View TL, HP recommends that you install
Command View TL on a single dedicated server (management station) on the LAN. However, it is
possible to install Command View TL on multiple servers. In this scenario, if one management station
claims a library for management, then that same library cannot be managed by any other management
station. A library can only be managed by one management station at a time.
Cross Linked libraries
A Cross Linked library is two to five library cabinets joined together by hardware, software, and firmware
to function as a single high-capacity library. The Cross Link Kit connects a designated primary cabinet
with another cabinet, which is called a secondary cabinet. Each Cross Link Expansion kit connects
another secondary cabinet to the system. The entire system is then referred to as a library. Specific
differences between primary and secondary cabinets are explained in this section.
Cross Link cabinets functionality
The primary cabinet controls the robotics of the secondary cabinets. The primary cabinet functions much
like a normal tape library, but it also retrieves data tapes from, sends data tapes to, and assigns storage
locations in the secondary cabinets. To do this, the OCP of a primary cabinet has functionality in
addition to that of a standalone library.
Secondary cabinets function mainly as storage units for the Cross Linked library. Their robotics are
controlled by the primary cabinet. Secondary cabinets have very limited options on the OCP.
OCPs for all three types of cabinets (standalone, primary, and secondary) are presented in
Operator
control panel (OCP) .
NOTE:
In all other ways, the Cross Linked library has the same capabilities as a standalone system. Any
differences in the operation of a Cross Linked library are noted in this guide.
