Changing SCSI IDs as Necessary
Note: Do not change the default SCSI ID settings for the library or the
drives unless they are set to the same value(s) already in use by
other devices on the same SCSI bus or unless required by your
software.
To change the SCSI IDs:
1. After you have confirmed the need to modify the
SCSI IDs of the library and/or the drives, power off
the library, the host computer, and any other
device on the SCSI bus.
2. Locate the SCSI ID switches on the back panel of
the library (see Rear Panel Components on page
34).
3. Determine the correct settings for the SCSI ID
switches. Each tape drive and the library require a
unique SCSI ID number.
4. Using the small screwdriver included with the
library, set the SCSI IDs of the drives and the
library to the correct values.
5. Verify that the SCSI IDs do not match the ID of any
other device on the SCSI bus including the SCSI ID
for the host computer’s controller card (usually 7).
6. Verify the unique settings of every device on the
SCSI bus.
Caution: Incorrectly set SCSI IDs will cause malfunctions.
See Chapter 3 Configuring the Library for further explanation of the use of the
configuration switch.
Figure 2-6 Use a small
screwdriver to set the switch to the
correct SCSI ID (default setting
shown). Do not turn the library
configuration (Config) switch.
