Identifying SCSI IDs 2
If your computer already has devices connected to the SCSI bus, you will
need to know their IDs to avoid any conflict with the new tape drive.
Here are some methods of finding out the information:
• Most computers display a list of SCSI devices and IDs during the
boot-up process. This usually scrolls past very fast. If you press the
[
Pause] key, you should be able to halt the scrolling and view the list.
• On Windows systems you can use Device Manager.
• If you have Novell NetWare installed, use its
LIST DEVICES
command.
If none of these is available to you, try the following sources of
information:
• The details of all installed devices and settings may have been written
down and stored with your computer's documentation (for new
computers, this is often done by the supplier).
• Your HBA's documentation should tell you which settings it uses.
• Look at each device to find out its ID. This is usually easy with
external devices. With internal devices, you will probably need the
help of the device's documentation to identify the SCSI ID setting,
which is usually set with jumpers.
Setting the SCSI ID on Quantum DAT Drives 2
See the relevant chapter of this User Guide for more details. Note that
host adapters check SCSI IDs only at power-on, so any changes will not
take effect until the host system is power-cycled.
• On internal Quantum drives, set the SCSI ID by attaching or
removing jumpers at the rear of the drive (see Check the Drive’s SCSI
ID on page 28).
