IBM 4560SLX Label Maker User Manual


 
library control software as a single library. For multi-module applications, the top
library module becomes the primary master module and all other libraries become
slave modules.
The library robotics pick up and place tape cartridges into an elevator so that
individual tapes can be passed up or down between libraries in a multi-unit
library configuration.
The 4560SLX Tape Library supports fail-over protection for multi-unit library
configurations. In the event of a master module failure, a pre-selected slave
module can become the fail over master. For example, if the primary master library
fails, you can invoke the library system fail-over mode. In this mode, one of the
connected slave units serves as the secondary master library, communicating with
the host system through the SCSI interface. The source of power to the cartridge
elevator drive motor is switched from the original primary master library to the
newly-assigned secondary master library.
