Chapter 2 — Architecture Overview
The component identifier for each drive is based on its location relative to
the frame and the DBA where it is installed, as viewed from the back of the
library (see Figure 16 on page 57). The component identifier for a drive is
shown as FRx/DBAx/fTYPE-DRVx, where:
 FRx is the number of the frame from left to right when viewed from the
 DBAx is the number of the DBA containing the drive.

 DRVx is the number of the drive bay in the DBA, as viewed from the
For example, Figure 18 shows the component identifier for a half‐height
Fibre Channel LTO drive installed in drive bay 1 of DBA 3 in Frame 2 
(FR2/DBA3/fLTO‐DRV1A) on the Drives screen. The Drive Type descriptor
indicates that the drive is an IBM LTO‐8 half‐height Fibre Channel drive.

The library's robotics and the library's drives connect to the host system
over a Fibre Channel arbitrated loop or fabric or a SAS fabric. These
connections carry two types of information:
 The commands from the storage management software that control the
 The data being transferred to and from a drive by the host.
The following sections describe Fibre Channel connectivity for the library's
robotics and the drives.
