Configuring and Operating the DLT4500 Mini-Library
DLT4000/DLT4500/DLT4700 Cartridge Tape Subsytem 4-7
4.4.2 Configuration Guidelines
The mini-library is factory set to SCSI ID 5, unless otherwise specified.
The system uses the SCSI ID to identify, or address, the mini-library. Follow these
guidelines when you configure the mini-library for your system:
If you are installing the mini-
library as ……
Then ……
The only SCSI device on the bus
or one of multiple SCSI devices
on the bus
Be sure to use a SCSI ID that is unique
from any other device or system ID on the
SCSI bus.
If you need to change the SCSI ID, see the
section on setting the SCSI ID, later in this
chapter.
The last or only device on the
SCSI bus
You must terminate the bus by installing a
terminator.
4.4.3 Setting the SCSI ID
Choose an unused SCSI ID between 0 and 7.
To set the SCSI ID via the front panel (See 4.8 Key Lock if the Operator Control Panel
is locked or disabled):
1. Press and hold the Display Mode button (about 5 seconds) until the SCSI ID SEL
message displays including the factory set SCSI ID (See 4.6.3 SCSI ID Select
Mode displays).
Example
SCSI ID SEL
SCSI ID 0
2. Keep pressing the Select button quickly until the ID number you want displays
(Figure 4-5).
3. Press the Display Mode button again. See the display message LDR RDY. At this
point, the mini-library drive cannot yet recognize the SCSI ID.
4. Issue a bus reset or turn the mini-library power off and then on again so the drive
can recognize the new SCSI ID.
