62 Drives in Tape Arrays
If the device is not detected on boot up, there is probably a problem with the
physical hardware: cables, termination, connections, power or the host bus
adapter itself. If the device is displayed during boot up but cannot be found in
the operating system, this is more likely to be a software problem.
Problems with the Host Computer
Most modern SCSI host bus adapters locate and display attached devices
when the system is booting up. If the device is not detected at this stage, there
is probably a problem with the physical hardware: cables, termination,
connections, power or the HBA itself.
If your drive is found on system boot up but cannot be found in the operating
system, this is more likely to be a software problem.
Computer does not boot up
Computer boots, but does not recognize the drive
Possible Cause Potential Solution
You have connected the tape drive to an
existing SCSI bus that has other devices
connected to it and the SCSI address of
the 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 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 computer’s boot disk
during the drive installation process.
Check that the cables to all devices are firmly connected.
Possible Cause Potential Solution
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 that it 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.)
