8mm Tape Library Configurations
The following configurations are supported by the tape library.
1. Base library configuration
2. Split library configuration
Base Library Configuration
In the base library configuration, the library elements are only accessible to the host
through the primary port (accessed using the connector on the rear of the library).
The second port is not enabled as a target.
Base Configuration External Cabling Requirements
The base library configuration supports the following SCSI BUS configurations.
Prior to entering the base library configuration ensure the library is cabled in one of
the following SCSI BUS configuration options:
1. Single Drive - Single Host SCSI Configuration
2. Dual Drive - Single Host SCSI Configuration
3. Dual Drive - Dual Host SCSI Configuration
Split Library Configuration
The split library configuration divides the library elements in half. The elements in
the lower magazine and Tape Drive 1 are assigned to the primary port. The
elements in the upper magazine and Tape Drive 2 are assigned to the secondary
port. The bonus slots and picker elements are shared by both ports. Elements are
only accessible through their respective ports.
Split Configuration External Cabling Requirements
The split library configuration supports the following SCSI BUS configurations. Prior
to entering the split library configuration ensure the library is cabled in one of the
following SCSI BUS configuration options:
1. Dual Drive - Single Host SCSI Configuration
2. Dual Drive - Dual Host SCSI Configuration
