CHAPTER 5: Using Your Tape Drive SDLT 220 and SDLT 320 Product Manual
5-18 March 2004 81-85002-01
System does not
recognize the tape
system. (cont.) SCSI bus may not be terminated
correctly. If tape system is last or only device on
bus (except for adapter), make sure
terminator is installed on tape system.
If tape system is not the last or only
device on the bus, check the cable
connections and ensure that the bus is
properly terminated at each end.
SCSI terminator may not be at end
of bus or more than two terminators
may be present. Ensure that a terminator is installed at
each end of the bus. One terminator is
usually installed at the host end of the
bus.
SCSI bus may be too long. Limit bus length to ANSI SCSI standard
for the SCSI interface being used.
Too many devices on the bus. Limit the number of devices on the bus
(including the SCSI adapter) to match the
limits of the interface being used.
A device may not have been turned
on and a valid SCSI ID may not
have been configured prior to the
system powering on and loading
BIOS. Turn drive power on first, and then turn
on power to the system. Do this so that
the drive is properly recognized by the
system.
The tape system does
not power up. No power is reaching the tape
system. Check the tape system’s power cable
connection at the back of the system.
Nonfatal or fatal errors
have occurred for
which the cause
cannot be determined. SCSI bus termination or the SCSI
bus cable connections may be
incorrect.
The AC power source grounding
may be incorrect (tabletop version).
Ensure the SCSI bus is terminated and
that all connections are secure. Use an
AC outlet for the tabletop tape unit on the
same AC line used by the host system.
