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 LED should be illuminated. If it is not, check that the power cord is connected
correctly to the tape drive. If the Ready LED 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.
4.
Are appropriate Tape 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 chapter on
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.

4.
Has the cartridge been write-protected, see
5.
Clean the tape heads with the cleaning cartridge, see
sure you are using the Ultrium Universal cleaning cartridge.
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.
9.
If the problem is still there, the problem probably lies with the drive or the host computer.
