Installing a DLTtape or Super DLTtape
Drive into an AIX System
1. Introduction
This document provides instructions for integrating a Quantum®DLTtape™ or
Super DLTtape™ drive into an IBM®RISC System/6000 running AIX®3.2, 4, or 5L.
1.1 Purpose and Scope
This document pertains to the following products:
•Tape drives: DLT 2000, DLT 2000XT, DLT 4000, DLT 7000, DLT 8000, SDLT 220,
SDLT 320, and SDLT 600. (The SDLT 220 tape drive was formerly known as the
Super DLT1.)
Note: The instructions in this document do not apply to DLT 7000 and DLT
8000 series tape drives and all Super DLTtape products, if being used
on AIX 3.2. In this case, you need to obtain a specific patch from IBM
in order install the tape drives. The patch will allow you to attach wide
SCSI devices such as the DLT 7000 and the DLT 8000 to narrow host
adapters on RS/6000. To obtain the patch (PTF U429285), go to IBM’s
Tech Support web site: http://service.software.ibm.com.
•Mini-libraries: DLT 2500, DLT 2500XT, DLT 2700, DLT 2700XT, DLT 4500,
and DLT 4700.

Note: Some of these library products are no longer supported by Quantum.
Information on such products is included for historical purposes only.
This document includes the following sections:
•“Installation” on page 4 describes how to install a DLTtape drive in an IBM RS/6000
running AIX 3.2, 4, or 5L.
•“Optional Attribute Settings” on page 8 provides information about setting the
DLTtape device attributes.
•“Special Device Files” on page 10 provides a list of special device files that can be
used to select tape drive options (re-tensioning, rewinding, and density settings).
•“Tape Cartridge Compatibility” on page 11 provides information about SDLT and
DLTtape cartridge and tape drive compatibility.
•“Using a DLTtape Mini-Library” on page 12 provides information about using a
DLTtape mini-library.
2. Installation
This section describes how to install the tape drive and how to configure the AIX
operating system to recognize and communicate with the tape drive.
2.1 Before You Begin
Before you install the tape drive, follow these steps:
1. If you have a DLT 2000, DLT 2500, or DLT 2700 product, make sure it uses version
V10 (or higher) controller firmware.

6464181-01 Rev B September 2004 5
Installing a DLTtape or Super DLTtape Drive into an AIX System
Note: The DLT 2000XT, DLT 2500XT, DLT 2700XT, DLT 4000, DLT 7000,
DLT 8000, SDLT 220, SDLT 320, and SDLT 600 tape drives do not
have firmware revision restrictions.
2. Make sure that the hardware has the appropriate SCSI interface for the tape drive. If
you have a SCSI single-ended (SE) tape drive, you need a SCSI SE interface; if you
have a SCSI low-voltage differential (LVD) or high-voltage differential (HVD) tape
drive, you need a SCSI LVD or HVD interface.
3. Obtain the appropriate manual for your tape drive as listed in Table 1. These manuals
provide detailed hardware installation instructions, including switch and jumper
settings and information about SCSI bus termination.
Note: To view these manuals online, go to: http://www.quantum.com/am/
service_support/downloads/default.htm.
2.2 Installing the Tape Drive
To install the tape drive, follow these steps:
1. Shut down the AIX system and disconnect the system AC power cable.
2. Connect the tape drive to the SCSI interface.
3. Power on the tape drive.

table as a Defined tape drive. To verify that the tape drive has successfully connected to
your operating system, follow these steps:
1. At the command line, type smit and press Enter.
2. Select Devices.
3. Select Tape Drives.
4. Select List All Supported Tape Drives.
5. The Output window displays a list of tape drives similar to the following table:
6. Select Done to return to the previous Tape Drive menu.

8. If the status is reported as Available, the installation is complete.
If the status of your tape drive is not yet listed as Available, and is still listed as Defined,
your tape drive is not ready for use. Follow these steps to make your tape drive available:
1. In the smit utility, select Devices.
2. Select Tape Drive.
3. Select Configure a Defined Tape Drive. A list of defined tape drives will be
displayed similar to the following table:
4. Select the tape drive that you are installing from the displayed list. You should be
able to identify your tape drive by its location code.
For example, in the sample list of tape drives above, rmt2 would be the tape drive at
Drawer 30, I/O Bus 58, Adapter Connector 00 and SCSI ID 6.

3. Optional Attribute Settings
The following information describes optional DLTtape drive attribute settings. These
optional settings include attributes such as Fixed vs. Variable Blocks, Variable
Length Block Size, Device Buffer Usage and Density Settings. To examine
and/or modify these attributes, follow these steps:
1. Under Devices, Tape drive selection in smit, select Change/Show
Characteristics of a Tape Drive. The system displays a table of defined tape
drives.
2. Select the tape drive via its logical address and location. The system displays the
attributes assigned to the tape drive. The tape drive attributes may be changed from

5. Tape Cartridge Compatibility
Table 4 and Table 5 provide information about tape cartridge and tape drive compatibility.
Use this matrix when determining which tape cartridges to use in your tape drive.
Note: The SDLT 220 and SDLT 320 tape drives can read, but not append
data to, DLTtape IV cartridges that were previously written by a
DLT 4000, DLT 7000, or DLT 8000 tape drive. The SDLT 600 tape
drive can read, but not append data to, Super DLTtape I and DLTtape
VS1 cartridges.

6. Using a DLTtape Mini-Library
The IBM AIX operating system does not support DLTtape media library device
commands. Therefore, you cannot use a DLT 2500, DLT 2500XT, DLT 2700,
DLT 2700XT, DLT 4500, or DLT 4700 in random access mode. You can access
the mini-library in sequential mode only.
For a detailed description of these access modes, refer to the appropriate product manual
for your DLTtape mini-library.
