Cannot write to or read
from tape.
Make sure that the cartridge is write enabled (move the
write-protect switch to the enabled position).
Make sure you have the appropriate data cartridge for your
library model.
Make sure you are using an Ultrium cartridge that has not
been degaussed. Do not degauss Ultrium cartridges.
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 your 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 ”Cleaning the tape drive” on page
52.
Cleaning
Cannot load the cleaning
cartridge
Make sure you are using an Ultrium universal cleaning
cartridge. (See”Cleaning the tape drive” on page 52.)
Contact your service representative.
Errors Displayed on Front Panel
“!” in library operator panel
inventory display
See ”Operator control panel (OCP) overview” on page 40 for
more information.
There is an error code on
the LCD
Look up the error code, try to resolve the failure, and power
cycle (see ”Tape library error codes” on page 68).
SCSI ID
Changed drive SCSI ID, but
the host server does not
recognize the new ID
Make 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 cycle power on the library after
changing the SCSI ID.
Reboot the host server. Tape library Performance The
library is not efficiently backing up data.
Make sure the library and tape drive are on their own SCSI
bus and not daisy-chained to another tape drive or to the
hard drive being backed up.
Make sure the library is connected to a LVDS SCSI bus and
there are no SE devices on the same bus, because this will
cause the entire bus to negotiate down to SE speed.
Use an Ultra320 SCSI bus and high-quality cabling with the
library.
Do not connect the library to a narrow SCSI bus.
