Spectra Logic 10000 manual Managing the Split-Bus Configuration

Chapter 3. Preparing the Library

Managing the Split-Bus Configuration

A split logical library appears to the host system as two independent physical libraries. In the example below, the library is configured as two logical libraries, where Logical Library 2 has 10 slots and its SCSI ID is set to 5.

The SCSI ID for Logical Library 2 is set to 5.

Logical Library 2 is allocated 10 slots.

The remaining slots in the library are allocated to Logical Library 1.

Figure 3-3Configuring a library for split-bus mode.

To identify the slots associated with the two logical libraries, the Move Tapes screen shows a blank row between the slots assigned to each library. In the screen shown below, slots 1-30 are assigned to Logical Library 1 (SCSI Port 1) and slots 31-40 are assigned to Logical Library 2 (SCSI Port 2).

Figure 3-4The Move Media screen changes in split-bus mode.

Physical slot numbers retain the original numerical sequence on the front panel interface. In this example, the slots in Logical Library 2 are mapped as 1-10 to the host system, but mapped as 31-40 on the Move Media screen.
