7 Troubleshooting
General Procedure
If a problem occurs, the first step is to try to establish whether the problem lies with the cartridge, the
drive, the host computer and connections, or the way the system is being operated.
Has the system just been installed?
There could be an installation problem:
1. Check through the information in the relevant installation chapter of this guide.
2. Has the system booted? If not, check that all hard disks are correctly seated in the hard disk bay
and then check the cabling between the disks and the SAS controller.
3. Has the system booted but the operating system has not seen the tape drive? Check that the drive
has power, the READY light should be illuminated. If it is not, check that the power cord is
connected correctly to the tape drive. If READY is illuminated, check the cabling between the
tape drive and the SAS controller. Ensure that the HBA port to which the drive is connected is
enabled. If an external drive was powered on after the server, power cycle the server.
4. Are appropriate Tape drivers and HBA drivers as well as supported application software installed
on the host?
5. Check the environmental conditions against the specified limits.

Are you using new cartridges or a different brand of cartridge? Have you been using the particular
cartridge for a very long time?
The problem could lie with the cartridge:
1. Check through the media information in Use the correct media (page 21).
2. Check that you are using an Ultrium cartridge. Compatible media can be recognized by the Ultrium
logo, which is the same as the logo on the front of your drive.
3. Use the correct media type: LTO-6 Ultrium 6.25 TB RW and LTO-6 Ultrium 6.25 TB WORM
cartridges for use with LTO–6 tape drives.
4. Has the cartridge been write-protected, see Write protecting cartridges (page 24)?
5. Clean the tape heads with the cleaning cartridge, see Cleaning cartridges (page 21). Make sure
you are using the Ultrium Universal cleaning cartridge, MR-LUCQN-01.
6. If the Tape LED is flashing, the cartridge is probably faulty. Try using a different cartridge.
7. Try the operation again.
8. If the problem still occurs and you have not yet replaced the cartridge, try using a different cartridge.
