This library can automatically detect host servers in the Storage Area Network
(SAN) and perform periodic self-tests to ensure that the library is fully operational.
If the library detects a problem, it isolates where the problem exists and provides
helpful instructions for resolving the problem. It also supports geographic
addressing, which means that you can install tape drives in any open drive slot,
and the library will automatically update its configuration model without requiring
you to assign the address of the drive yourself.
The control module houses the central intelligence of the library; without it, the
library cannot function. The control module contains several essential components,
including the library control blade and the robotic picker assembly. The library
control blade controls the library’s functions, while the robotic picker assembly is
responsible for physically retrieving data cartridges from the library’s storage slots,
inserting the cartridges into the appropriate tape drive, and returning them to their
appropriate storage slot. The control module also provides a configurable I/O
