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
The server boots but does not recognize the tape drive
Possible reason Recommended action
You have connected the tape drive to an
existing SCSI bus that has other devices
connected to it and the SCSI address of
your HP StorageWorks Ultrium drive is
identical to the address used by another
device.
Make sure that each device on the SCSI bus has a
unique ID. We recommend that the
HP StorageWorks Ultrium tape drive is connected
to a dedicated host bus adapter. Do not connect
the drive to a disk RAID controller as this is not
supported.
You have installed an additional SCSI
host bus adapter and its resources are
clashing with an existing adapter.
Remove the new host bus adapter and check the
server documentation.
You have disconnected the power or SCSI
cable from the server’s boot disk during
the drive installation process.
Check that the cables to all devices are firmly
connected.
Possible reason Recommended action
The power or SCSI cable is not connected
properly.
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.
The SCSI bus is not terminated correctly. 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.)
The tape drive’s SCSI ID address is not
unique.
Make sure that each device connected to the SCSI
controller has a unique SCSI ID. Remember that 7
is normally reserved for the host bus adapter. (You
can run HP Library & Tape Tools to check the SCSI
IDs of each device attached to the SCSI bus, see
page 33.)
