94 Troubleshooting
Solution
The Autoloader was unable to complete the requested operation with the
selected tape cartridge.
Use only cartridges that are compatible with the drive type (see
cartridges (page 30)).
Use the correct type of cartridges for the operation. For example, use a
cleaning cartridge for cleaning.
Make sure you are using an Ultrium Universal cleaning cartridge (see
cartridges (page 30)).
The cleaning cartridge is expired. A cleaning cartridge will expire after 50
cleaning cycles.
If the Media Attention LED is cleared and the drive has been cleaned, and then
immediately re-displays each time a particular cartridge is reloaded, that
cartridge should be suspected as being defective.
If this occurs, export the cartridge and load a known good cartridge. In
some cases, a cartridge can be worn out, have a defective Cartridge
Memory, or have been formatted as a Firmware Upgrade Cartridge.
Any cartridge that is suspected of being defective or contaminated should
NOT be reused in any drive.
If the bad cartridge is a cleaning cartridge, it might be expired.
