TAPE APPLICATION NOTE
CG00000-016401
CONNECTING THE M2488 TO AN
IBM RISC SYSTEM 6000 RUNNING AIX 3.2
FOREWORD
This application note describes the procedure to use when attaching to an IBM RISC System 6000 running AIX 3.2.
Instructions cover installing the M2488 tape drive hardware and configuring the system to communicate with the
M2488. The system manuals provide detailed descriptions of many of the operations performed in this application
note.
PROCEDURE
You must be superuser to perform the operations in this procedure.
Displays are presented in this typeface: /etc/passwd
User entries are presented in this typeface: boot
STEP ACTION
1 Shut down the IBM RS/6000 and power the unit off.
2 Ensure that the M2488 is properly terminated and connect the M2488 tape drive to the RS/6000’s SCSI
controller. The M2488 Cartridge Tape Drive Product Guide (part number CG00000-0115xx) may be
useful for configuration of the M2488. Set the SCSI target ID to either 4 or 5. Address 4 will be used for
the examples in this application note.
3 Power on the M2488 and wait for the power cycle to complete.
4 Turn the RS/6000 AC power on and reboot the system. The key should be set to the “Normal” position.
5 Log on as root.
6 During the boot sequence, the system adds the M2488 to its customized configuration table as a defined
tape drive. Verify that the system has added the M2488.
From the aixterm command line, type smit, then choose:
• Select Devices
• Select Tape Drive
• Select List All Defined Tape Drives

STEP ACTION
6 (con’t) The system will display the tape drives connected to SCSI I/O controller(s) as in the example shown
below (note that under “status” below, the system may return a status of “Defined” or “Available”:
name status location description
rmt0 Defined 00-00-0S-40 Other SCSI Tape Drive
Where:
name the logical name of the M2488 (rmt0)
status whether the drive is Defined (known, but not ready for use) or Available (ready for use). If the sta-
tus is reported as “Defined” go to Step 7. If the status is reported as “Available” go to Step 9.
location the SCSI id of the M2488 (5 in the sample) and the address of the SCSI I/O controller (the 0 that
follows the 5 in the sample)
description a short description of the tape drive type. The M2488 is added as “Other SCSI tape drive”
If status was returned as “Defined”, the M2488 has been added to the defined tape drive list as
described in Step 6. Now, change the M2488's status from Defined to Available (defined and ready
for use).
When you are ready, select Done
7 From the smit Devices - Tape Drive window select:
•Configure a Defined Tape Drive
The system displays a list of defined tape drives. Select the M2488 by its logical address and loca-
tion. The system responds by reporting the status of your command.
To verify that the system has changed the status of the M2488 from defined to available, select
List All Defined Tape Drives. The system displays:
name status location description
rmt0 Available 00-00-0S-40 Other SCSI Tape Drive
8 If the system has returned a status of “Available,” you may want to change the attributes of the
M2488 to meet the needs of the customer's system. Follow these instructions to change tape drive
attributes.
9 From the smit Devices - Tape Drive window select:
•Change / Show characteristics of a Tape Drive
The system displays a table of all of its defined tape drives. Select the M2488 by its logical address
and location.
10 Setting or changing M2488 Attributes
The system will display the attributes assigned to the M2488 tape drive.You can change the follow-
ing attributes as necessary (recommended settings are in UPPER case)

STEP ACTION
10 (con’t)
BLOCK size (0=variable length) 0
Use DEVICE BUFFERS during writes YES
Use EXTENDED filemarks YES
Do not set to NO
BLOCKSIZE for variable length support 0
DENSITY setting #1 09
DENSITY setting #2 09
Set delay after a FAILED command 10
Set maximum delay for the READ/WRITE command 120
Select DO.
11 To leave smit, select Done,Cancel,Cancel, and Cancel. The smit window will close.
12 To test the M2488 save the “passwd” file to tape using the tar command:
tar -cvf /dev/rmt0 /etc/passwd
The system responds with: a /etc/passwd 1 blocks
Note: depending on the size of the file, a different number of blocks may be reported.
13 Verify that the “passwd” file was saved to tape by executing the following command:
tar tf /dev/rmt0
The system responds with: /etc/passwd
