Description
Partitions
Partitions are virtual sections within a library that present the appearance of multiple, separate libraries for
purposes of file management, access by multiple users, or dedication to one or more host applications.
Organizing the library into partitions divides the resources into virtual sections. If one of the resources is not
available due to a failure or other cause, the other partitions and their assigned components are still
available. Partitions can also be used to control access to portions of the library by granting permissions to
user accounts to access certain partitions.
For more information on partitions, see
Working With Partitions
on page 34.
Logical Unit Numbering (LUN)
Logical unit numbering (LUN) is the means by which the tape drives send medium changer commands from
a host to the library controller via the tape drive’s Library Drive Interface (LDI) port and its sled’s Controller
Area Network (CAN) interface. The purpose of the LUN interface is to eliminate the requirement for a host
interface on the library control blade, thereby reducing system cost.
User Interface
The operator panel is located on the front door of the control module and allows users to work locally on the
library via the user interface. The web client interface allows users to view and perform library functions from
remote sites and is accessible through a browser. The operator panel and web client interface contain a
similar user interface and functionality.
See
Understanding the User Interface
on page 21 for more information about the operator panel and the
web client interface.
Control Path Modification
The control path tape drive is used to connect a partition to a host application. Only one tape drive can be
selected as the control path at one time. By default, the first tape drive assigned to a partition is designated
the control path. In the event that the control path connection to the host application fails, you can select a
new control path for the partition.
Support for WORM
Tandberg StorageLibrary T128 tape libraries support WORM (write once, read many) technology in LTO-3
tape drives. WORM allows non-rewriteable and non-erasable data to be written and provides extra data
security by prohibiting accidental data erasure. The WORM feature is supported whenever you use WORM
cartridges.
