HP VS160 - StorageWorks DLT Tape Drive Troubleshooting Manual page 32

Testing after installation
Remember that the system recognizes devices during boot-up. If you swap or connect a
product when your system is running, you will need to reboot the system. Rebooting the system
will reset devices and will often resolve problems. It is good practice to reboot every time you
add a driver or install firmware.
Caution Never power off the drive while a cartridge is still loaded or during a firmware upgrade.
The server does not reboot after installation
Possible reason
You have installed an additional SCSI host
bus adapter and its resources are clashing
with an existing adapter.
You have disconnected the power or SCSI
cable from the server's boot disk during the
drive installation process.
The server boots but does not recognize the tape drive
Possible reason
The power or SCSI cable is not connected
properly.
The SCSI bus is not terminated correctly.
The tape drive's SCSI ID address is not
unique.
The tape drive was switched on after the
server booted up. The server only checks for
SCSI devices at power-on.

Recommended action
Remove the new host bus adapter and check the
server documentation.
Check that the cables to all devices are firmly
connected.
Recommended action
Check that the Power LED is on. Check that the
cables to the tape drive are firmly connected. Ensure
that the SCSI cable is LVDS-compliant and does not
have any bent pins. Replace, if necessary.
Check that the SCSI bus is actively terminated. (Refer
also to the documentation for your SCSI controller
and any other SCSI devices you may have.)
Make sure that each device on the SCSI bus has a
unique ID.
We recommend that the tape drive is connected to a
dedicated host bus adapter. Do not attach the drive
to the same SCSI bus as your disk drive, or to a RAID
unless it is a ProLiant server with a
controller,
Smart Array 6i RAID controller
Switch on the tape drive and then reboot the server.
