HP ESL E-series Tape Libraries - Manual (Page 28)

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.
Space requirements
In addition to the space required for standalone libraries, a CLM library requires 52 inches (130 cm)
of clear space to the left of the primary cabinet as you face the front of the cabinets. See the section
called Floor space in HP StorageWorks ESL E-Series Tape Library unpacking and installation guide
for further information.
System components
The primary cabinet of a Cross Linked Library must be an ESL 712e or 630e, or an ESL 322e or 286e
that has already been expanded to full capacity using purchased licenses installed using Command
View TL. Secondary cabinets must be ESL 712e or 630e libraries.
