problems, see Diagnostic Tools and Performance (page 44). We also recommend the detailed

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. Does an error appear during the boot sequence about a change to the RAID configuration?
This error only appears if you have used the supplied cable to replace an existing SAS cable.
Check the cabling between the disks and the SAS controller. If the problem persists, you have
probably disconnected a hard disk drive bay that was in use. See Option 3: Connect cable
to port on host SAS controller and replace existing SAS cable (page 24) for more information.
4. 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.
5. Are appropriate Tape drivers and HBA drivers as well as supported application software
installed on the host?
6. 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 35).
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.
