Solution Problem
Make sure you are using data and cleaning cartridges that are
compatible with the drive and model of your device (see “
Tape
cartridges ” on page 43) and that you are using the correct cartridge
type for the operation. The device automatically unloads incompatible
cartridges, the
Attention LED flashes, and an exclamation point (!) displays
in the inventory display for the indicated slot number. Export the media
to clear the state.
Cleaning or data cartridge
incompatible with drive.
• Make sure that the cartridge is not a WORM cartridge that has
already been used.
• Make sure that the cartridge is write enabled (move the write-protect
switch to the enabled position).
• Make sure the data cartridge is compatible with the drive model. LTO
tape drives can read data cartridges from two generations back and
write to data cartridges one generation back. (See “
Backward read
compatibility ” on page 47.)
• Make sure you are using an Ultrium cartridge that has not been de-
gaussed.
Do not degauss Ultrium cartridges!
• Make sure that the cartridge has not been exposed to harsh environ-
mental 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 tape drive ” on page 79.)
Cannot write to or read from tape.
