Chapter 5. Troubleshooting
This chapter provides suggestions for troubleshooting your drives in the unlikely
event you encounter a problem with them.
SCSI ID problems
Each SCSI device on the same SCSI bus must have a unique SCSI ID. The default
SCSI ID for internal and external drives is 6. You should leave this default SCSI ID
unchanged unless another device on the SCSI bus is already using this ID.
If the default SCSI ID is already in use, you can change the default SCSI ID on the
drive using either jumpers on the back of the internal tape drives or the SCSI ID
Selector switch on the back of the external SCSI drives.
SCSI termination problems
The DDS Gen 5 drive does not provide SCSI termination. Termination is provided
by the included SCSI cable.
Mounting hardware problems
The internal drives are designed to install in most servers using the hardware
accompanying the drives, without requiring additional items. However, if your
server requires additional items to install the internal drives, or if any original
server components are damaged or lost, contact IBM Technical Support.
Drive does not work
If the internal tape drive does not work:
1. Check the power connection to the drive.
2. If the connection is secure, replace the power cable with one that is known to
3. If the drive still does not work, contact IBM Technical Support
Power-On Self-Test fails
If the drive fails its Power-On Self-Test:
1. Check for a cartridge in the drive. If you find one, eject it.
2. Power-down the drive and power it up again.
3. If the drive still fails its Power-On Self-Test, contact IBM Technical Support.
Computer does not boot
If the computer does not boot after you install the drive:
1. You forgot to reattach the computer's power cable, which you removed when
