8.1 Before You Begin

Currently there are two types of SCSI tape drive assemblies available. See
page 8-1. LTO3 models, which require termination at both ends of the SCSI bus and
LTO4 models, which are self terminating in the tape drive assembly itself.
8.1 Before You Begin
Before installing the tape drive assemblies, create a map of where each tape drive should
go. See Figure 8-10 on page 8-11

8.1.1 Guidelines for Tape Drive Installation
When determining where to install the tape drives, consider the following rules and
guidelines:
• Drive filler assemblies. For safety and UL compliance, a drive filler assembly
(see
empty tape drive slots, the handler will be prevented from moving when power is
applied to the library.

• Logical libraries. To simplify logical library definition and maintenance, use
side-by-side locations within a drive bay when installing the tape drives for a
logical library. As required, you can install drive filler assemblies to reserve
specific tape drive locations for future growth. Or, you can install the tape drives
for more than one logical library in a single bay.
• Tape drive interface. Although you can install SCSI and Fibre Channel tape
drives in a single bay, you may want to use the lowermost bays for SCSI tape
drives. This will help minimize cable length issues if you connect the HBA and
