• Make sure the cartridge has not been written using an
incompatible format.
• Make sure the cartridge is an acceptable format for your
drive type. See the tape drive’s reference manuals for
details.
• Make sure the cartridge has not been exposed to harsh
environmental or electrical conditions and is not physically
damaged in any way.
• Many backup applications do not read or write to cartridges
that were created using a different backup application. In
this case, you might have to perform an erase, format, or
label operation on the cartridge.
• Make sure you understand any data protection or overwrite
protection schemes your backup application might be
using, which could prevent you from writing to a given
cartridge.
• Retry the operation with a different, known good tape.
• Clean the tape drive. See the section called “Using the
Cleaning Cartridge” in the User and Installation Guide’s
“Maintenance” chapter.
SCSI problems
Changed drive or loader SCSI
ID, but the host server system
does not recognize the new ID
• Make sure 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 you reboot the autoloader after changing the
SCSI ID.
• Reboot the host server system.
The 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 the SCSI cables are connected to the rear of the
loader. See the section called “Connecting the SCSI Bus
Cable” in the “Installation” chapter.
• Make sure 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 length.
• Verify that the loader SCSI ID and the drive SCSI ID are set
to unique SCSI IDs that are 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.
• Reboot the host system when the loader has completed its
power on sequence.
• Contact your service representative.
