If you have just installed a SCSI host adapter card in your computer and the computer did not boot up when you switched it on, the new adapter is the likely cause of the problem. Refer to your host adapter documentation to check that the adapter is configured correctly. There may be a loose connection. Turn off the computer's power.

The computer's memory registers may not have cleared properly. Turn off the computer's power for at least 20 seconds, then turn it on again. This process of "cycling power" restarts processes and clears memory. The computer takes a long time to boot up. This can occur when the BIOS on a host adapter card is enabled, but there is no bootable SCSI device connected to it. You may be able to disable the host adapter BIOS to resolve this problem. Check the host adapter manual for instructions on how to disable the BIOS. The computer hangs. Check that you have no hardware conflicts in your hardware or software configuration, such as two devices with the same SCSI ID. Refer to your hardware and software installation documentation. Make sure that no two devices have the same SCSI ID. Check that the SCSI bus is properly terminated. 5-3

Things to Try First
The first step in problem-solving is establishing whether the problem lies with the tape,
the drive, the host computer and its connections, or with the way the system is being
operated. If none of the following advice helps you to solve the problem, call for
service. The HP Customer Support numbers are listed in Appendix B.
TapeAssure
The TapeAssure software provided on the
HP SureStore Tape
CD-ROM can be used
as a diagnostic tool if your computer is up and running. Install TapeAssure from the
CD-ROM and follow the instructions on the screen.
Problems with Your Computer
Problem
Possible Cause
Potential Solution
The computer does not
boot up.
If you have just installed a SCSI host
adapter card in your computer and the
computer did not boot up when you
switched it on, the new adapter is the
likely cause of the problem.
Refer to your host adapter documentation
to check that the adapter is configured
correctly.
There may be a loose connection.
Turn off the computer’s power.
Disconnect and then reconnect all cables
that may have been moved during
installation. Sometimes just reconnecting
a cable aligns it correctly or adjusts the
pins to make the connection.
The computer’s memory registers may
not have cleared properly.
Turn off the computer’s power for at least
20 seconds, then turn it on again. This
process of “cycling power” restarts
processes and clears memory.
The computer takes a long
time to boot up.
This can occur when the BIOS on a host
adapter card is enabled, but there is no
bootable SCSI device connected to it.
You may be able to disable the host
adapter BIOS to resolve this problem.
Check the host adapter manual for
instructions on how to disable the BIOS.
The computer hangs.
Check that you have no hardware
conflicts in your hardware or software
configuration, such as two devices with
the same SCSI ID.
Refer to your hardware and software
installation documentation. Make sure
that no two devices have the same SCSI
ID. Check that the SCSI bus is properly
terminated.
