Media barcode labels
Make sure the barcode labels are applied in the correct
orientation on the cartridge. See
Labeling
Cartridges
for
the
Barcode
Reader
.
Make sure there
are
no wrinkles on the l
abel.
Make sure that
StorageLibrary
specific labels are used.
If all of the above are OK, replace the label with a new one.
If problem continues, contact your service representative.
Data cartridge incompatible with
drive
Make sure you are using a data cartridge that is compatible
with the drive. See the tape drives reference manuals for
details.
The SW backup application detects if an incompatible data
cartridge is used, and communicates this to the
user
.
Remove the cartridge from the library.
Cannot wr
ite to or read from
tape
Make sure that the cartridge is write enabled (move the write
-
protect switch to the enabled position).
Make sure that the cartridge has not been written using an
incompatible format.
Make sure that the cartridge is an acceptable f
ormat for your
drive type.
See the tape drives reference manuals for details.
Make sure that 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 may have to perform an erase, format, or label
operation on the cartridge.
Make sure you understand any data protection or overwrite
protection schemes that yo
ur backup application may 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

SCSI problems
Changed SCSI ID, but the host
server system does not
recognize the new ID
Make sure that all SCSI devices on the same bus have unique
ID nu
mbers.
If the SCSI bus is narrow (50
-
pin) only SCSI IDs 0 through 7
are available.
Make sure that you reboot the library after changing the SCSI
ID.
Reboot the host server system.
The tape drive does not
respond on the SCSI bus to the
host
Verify that a S
CSI 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
library. See
Connecting
Library
Cables
(SCSI).
