SCSI problems
Changed drive or loader SCSI
ID, but the host server system
does not recognize the new ID
• M ake sure that all SCSI devices on the same bus have
unique ID numbers.
• If the SCSI bus is narrow (50 - pin) only SCSI IDs 0 through
7 are available.
• Make sure that you reboot the autoloader after changing
the SCSI ID.
• Reboot the host server system.
Th e tape drive responds on the
SCSI bus to the host, but the
loader does not respond
•Verify that a SCSI terminator is attached to both the last and
first SCSI device on the SCSI bus.
• Verify that the SCSI cables are connected to the rear of the
loader. See chapter “Installation”, section “connecting the
SCSI bus cable”.
• Make sure that the correct host controller card is installed.
• Verify that the SCSI cables are not damaged and that the
total SCSI cable length is not exceeding the maximum
required lengt h.
• Verify that the loader SCSI ID and the drive SCSI ID are set
to unique SCSI IDs that is not used by any other SCSI
device on the same bus.
• Verify that the host application and the device drivers are
installed with the most resent patches to support the loader
• Reboot the loader by turning power off from the rear of the
loader and then on.
